-+ help
-+ Saying Y here includes support for SquashFS 3.0 (a Compressed Read-Only File
-+ System). Squashfs is a highly compressed read-only filesystem for Linux.
-+ It uses zlib compression to compress both files, inodes and directories.
-+ Inodes in the system are very small and all blocks are packed to minimise
-+ data overhead. Block sizes greater than 4K are supported up to a maximum of 64K.
-+ SquashFS 3.0 supports 64 bit filesystems and files (larger than 4GB), full
-+ uid/gid information, hard links and timestamps.
-+
-+ Squashfs is intended for general read-only filesystem use, for archival
-+ use (i.e. in cases where a .tar.gz file may be used), and in embedded
-+ systems where low overhead is needed. Further information and filesystem tools
-+ are available from http://squashfs.sourceforge.net.
-+
-+ If you want to compile this as a module ( = code which can be
-+ inserted in and removed from the running kernel whenever you want),
-+ say M here and read <file:Documentation/modules.txt>. The module
-+ will be called squashfs. Note that the root file system (the one

-+ has to re-read fragments less often from disk, at the expense
-+ of extra system memory. Decreasing this amount will mean
-+ SquashFS uses less memory at the expense of extra reads from disk.

-+ Kmalloc memory is the standard kernel allocator, but it can fail
-+ on memory constrained systems. Because of the way Vmalloc works,
-+ Vmalloc can succeed when kmalloc fails. Specifying this option
-+ will make SquashFS always use Vmalloc to allocate the
-+ fragment cache memory.

-+ *
-+ * Authors: Patrick McHardy, <kaber@trash.net>
-+ *
-+ * The first version was written by Martin Devera, <devik@cdi.cz>
-+ *
-+ * Credits: Jan Rafaj <imq2t@cedric.vabo.cz>
-+ * - Update patch to 2.4.21
-+ * Sebastian Strollo <sstrollo@nortelnetworks.com>
-+ * - Fix "Dead-loop on netdevice imq"-issue
-+ * Marcel Sebek <sebek64@post.cz>
-+ * - Update to 2.6.2-rc1
-+ *
-+ * After some time of inactivity there is a group taking care
-+ * of IMQ again: http://www.linuximq.net
-+ *
-+ *
-+ * 2004/06/30 - New version of IMQ patch to kernels <=2.6.7
-+ * including the following changes:
-+ *
-+ * - Correction of ipv6 support "+"s issue (Hasso Tepper)
-+ * - Correction of imq_init_devs() issue that resulted in
-+ * kernel OOPS unloading IMQ as module (Norbert Buchmuller)
-+ * - Addition of functionality to choose number of IMQ devices
-+ * during kernel config (Andre Correa)
-+ * - Addition of functionality to choose how IMQ hooks on
-+ * PRE and POSTROUTING (after or before NAT) (Andre Correa)
-+ * - Cosmetic corrections (Norbert Buchmuller) (Andre Correa)
-+ *
-+ *
-+ * 2005/12/16 - IMQ versions between 2.6.7 and 2.6.13 were
-+ * released with almost no problems. 2.6.14-x was released
-+ * with some important changes: nfcache was removed; After
-+ * some weeks of trouble we figured out that some IMQ fields
-+ * in skb were missing in skbuff.c - skb_clone and copy_skb_header.
-+ * These functions are correctly patched by this new patch version.
-+ *
-+ * Thanks for all who helped to figure out all the problems with
-+ * 2.6.14.x: Patrick McHardy, Rune Kock, VeNoMouS, Max CtRiX,
-+ * Kevin Shanahan, Richard Lucassen, Valery Dachev (hopefully
-+ * I didn't forget anybody). I apologize again for my lack of time.
-+ *
-+ *
-+ * 2008/06/17 - 2.6.25 - Changed imq.c to use qdisc_run() instead
-+ * of qdisc_restart() and moved qdisc_run() to tasklet to avoid
-+ * recursive locking. New initialization routines to fix 'rmmod' not
-+ * working anymore. Used code from ifb.c. (Jussi Kivilinna)
-+ *
-+ * 2008/08/06 - 2.6.26 - (JK)
-+ * - Replaced tasklet with 'netif_schedule()'.
-+ * - Cleaned up and added comments for imq_nf_queue().
-+ *
-+ * 2009/05/02 - Backported 2.6.27 fixes to 2.6.26 (Jussi Kivilinna)
-+ * - Add skb_save_cb/skb_restore_cb helper functions for backuping
-+ * control buffer. This is needed because some networking layers
-+ * on kernels before 2.6.27 overwrite control buffer when they
-+ * should not. These errornous uses (wireless for example) of cb
-+ * were found when qdisc-layer started using cb in 2.6.27. As we
-+ * don't want to break up any code, even if it's buggy, use
-+ * same backup-cb trick as used with 2.6.27-patch.
-+ * - Add better locking for IMQ device by using spin_lock_bh
-+ * instead of spin_lock. There was problem where NIC-interrupt
-+ * would happen while IMQ-spin_lock was held which could lead to
-+ * deadlock. Hopefully this will solve the SMP issues.
-+ * - Fix rmmod not working.
-+ * - Use netdevice feature flags to avoid extra packet handling
-+ * by core networking layer and possibly increase performance.
-+ *
-+ * Also, many thanks to pablo Sebastian Greco for making the initial
-+ * patch and to those who helped the testing.
-+ *
-+ * More info at: http://www.linuximq.net/ (Andre Correa)

-+ The IMQ device(s) is used as placeholder for QoS queueing
-+ disciplines. Every packet entering/leaving the IP stack can be
-+ directed through the IMQ device where it's enqueued/dequeued to the
-+ attached qdisc. This allows you to treat network devices as classes
-+ and distribute bandwidth among them. Iptables is used to specify
-+ through which IMQ device, if any, packets travel.

-+ * mangle the client_port. If none is specified, it is autodetected. It

-+
-+2005-09-21 Klaus Wenninger <klaus.wenninger@siemens.com>
-+
-+ * file.c: readdir: fix for a bug that caused directory entries
-+ to show up twice when using storage filesystems such as
-+ minixfs or pramfs.
-+
-+2005-06-30 Eric Lammerts <eric@lammerts.org>
-+
-+ * fix for an oops when overwriting a binary thats beeing
-+ executed.
-+
-+2005-06-09 <mk@mary>
-+
-+ * Renamed overlay to mini_fo-overlay.
-+
-+ * Added mini_fo-merge script to allow merging of storage and base
-+ after making modifications.
-+
-+2005-05-22 root <mk@mary>
-+
-+ * Added overlay script that allows to easily mount mini_fo ontop
-+ of a given base directory
-+
-+2005-05-10 <mk@mary>
-+
-+ * inode.c: xattr functions return -EOPNOSUPP instead of
-+ -ENOSUPP, what confuses "ls -l"
-+
-+ * Changed license from LGPL to GPL.
-+
-+2005-05-08 root <mk@mary>
-+
-+ * Makefile: clean it up and added make install and make
-+ uninstall.
-+
-+2005-05-06 <mk@mary>
-+
-+ * merged devel branch back to main. [v0-6-0-pre3]
-+
-+ * removed unused files print.c and fist_ioctl. [devel-0-0-18]
-+
-+ * ioctl: removed fist_ioctl stuff, that is not needed for
-+ now.
-+
-+2005-05-03 <mk@mary>
-+
-+ * file.c: simplified mini_fo_open and mini_fo_setattr using
-+ new state changing functions. [devel-0-0-17]
-+
-+ * inode.c: Fixed getattr state bug (see below) in 2.4 function
-+ mini_fo_inode revalidate.
-+
-+ * inode.c: found an other bug in mini_fo_getattr. States are not
-+ reliable in this function, as a file can be opened, unlinked and
-+ the getattr function called. This results in a deleted dentry
-+ with an inode. Fix is to ignore states and simply use the inode
-+ available.
-+
-+2005-04-29 <mk@mary>
-+
-+ * file.c: Bugfix and cleanup in fasync and fsync. [devel-0-0-16]
-+
-+ * file.c: do not use mini_fo_lock so the generic version is
-+ used (I guess).
-+
-+ * inode.c: getattr, never call getattr on lower files, as this
-+ will cause the inum to change.
-+
-+ * inode.c: rename_reg_file renamed to rename_nondir, as it
-+ doesn't matter as long it't not a dir. Removed all
-+ rename_dev_file etc.
-+
-+ * tagged as devel-0-0-15
-+
-+ * inode.c: added support for chosing support for extended
-+ attrs at compile time by XATTR define in mini_fo.h .
-+
-+ * inode.c: fixed mini_fo_getattr to use mini_fo inode and not
-+ lower again, what avoids inode number changes that confused
-+ rm again. This is the proper solution.
-+
-+2005-04-24 <mk@mary>
-+
-+ * all files: updated Copyright notive to 2005. [devel-0-0-14]
-+
-+ * inode.c: fixed mini_fo_getattr to not change the inode
-+ number, even if lower files change.
-+
-+ * super.c: fixed a bug that caused deleted base file to show
-+ up suddenly after some time, or after creating a special
-+ file. The problem was that after some time or after special
-+ file creating sync_sb_inodes is called by the vfs, that
-+ called our mini_fo_put_inode. There was (wrongly) called
-+ __meta_put_lists, that nuked the lists, although the inode
-+ was going to continue its life. Moving __meta_put_lists to
-+ mini_fo_clear_inode, where an inode is really destroyed,
-+ solved the problem.
-+
-+
-+2005-04-23 <mk@mary>
-+
-+ * state.c, aux.c: more cleaning up and
-+ simplifications. [devel-0-0-13]
-+
-+ * inode.c: implemented mini_fo_getattr, that was required for
-+ 2.6 because inode_revalidate has been remove there, and the
-+ old "du" bug returned.
-+
-+
-+2005-04-20 <mk@mary>
-+
-+ * aux.c: get_neg_sto_dentry(): allow to be called for dentries
-+ in state UNMODIFIED, NON_EXISTANT _and_ DELETED.
-+
-+2005-04-19 <mk@mary>
-+
-+ * Fixed a bug under 2.6 that caused files deleted via mini_fo
-+ not to be deleted properly and therefore the fs filled up
-+ untill no memory was left. [devel-0-0-12]
-+
-+ * Added basic hard link support. This means that creating
-+ hardlinks will work, but existing ones will be treated as
-+ individual files. [devel-0-0-11]
-+
-+2005-04-17 <mk@mary>
-+
-+ * Bugfixes
-+
-+2005-04-13 root <mk@mary>
-+
-+ * Added file state.c for the state transition
-+ functions. Doesn't work very well yet, though...
-+
-+2005-04-12 <mk@mary>
-+
-+ * Porting to 2.6 started, which is easier than expected, also
-+ due to Olivier previous work.
-+
-+2005-04-08 <mk@mary>
-+
-+ * Fixed the bug that caused du to return invalid sizes of
-+ directory trees. The problem was that
-+ mini_fo_inode_revalidate didn't always copy the attributes
-+ from the base inode properly.
-+
-+2005-04-01 Markus Klotzbuecher <mk@chasey>
-+
-+ * Merged devel branch back to main trunk and updated the
-+ RELEASE notes. This will be 0-6-0-pre1.
-+
-+2005-03-31 Markus Klotzbuecher <mk@chasey>
-+
-+ * Fixed some bugs in rename_reg_file, that only showed up in
-+ the kernel compile test. Kernel compiles cleanly ontop of
-+ mini_fo, now also make mrproper etc. work. Seems pretty stable.
-+
-+2005-03-28 Markus Klotzbuecher <mk@chasey>
-+
-+ * Many, many directory renaming bugfixes and a lot of other
-+ cleanup. Dir renaming seems to work relatively stable.
-+
-+2005-03-22 Markus Klotzbuecher <mk@chasey>
-+
-+ * Finished implementing lightweight directory renaming. Some
-+ basic testing indicates it works fine.
-+ Next is to implement testcases for the testsuite and confirm
-+ everything is really working ok.
-+
-+2005-03-18 Markus Klotzbuecher <mk@chasey>
-+
-+ * Finished implementing meta.c stuff required for directory
-+ renaming.
-+
-+2005-03-17 Markus Klotzbuecher <mk@chasey>
-+
-+ * Fixed all compile warnings + an extremly old bug that
-+ somehow crept in while reworking the wol stuff to the META
-+ system. Turning on -Werror again... :-)
-+
-+ * Fixed some bugs in the new rename_reg_file function.
-+
-+ * Rewrote mini_fo rename and split it into several
-+ subfunctions, that handle the different types
-+ seperately. Rewrote the regular file function aswell, as it
-+ was implemented somewhat inefficient.
-+
-+2005-03-16 Markus Klotzbuecher <mk@chasey>
-+
-+ * Implemented new META subsystem, removed old WOL stuff in favor
-+ if it.
-+
-+ * After some basic testing everything seems ok...
-+
-+2005-03-11 Markus Klotzbuecher <mk@chasey>
-+
-+ * Renaming a non regular file caused trouble because I always
-+ tried to copy the contents. Now I only do this for regular
-+ files. mini_fo_rename still isn't implemented properly, renaming
-+ of device files, symlinks etc. results in a empty regular file
-+ instead of the proper type.
-+
-+ * Directory renaming suddenly works! What a surprise! I guess
-+ this is because renaming is implemented as making a copy and
-+ removing the original. Still this might not work
-+ everywhere...
-+
-+2005-03-09 Markus Klotzbuecher <mk@chasey>
-+
-+ * Bugfix, when a mini_fo directory that exists in storage
-+ (state: MODIFIED, CREATED and DEL_REWRITTEN) is deleted, a
-+ possibly existing WOL file contained in it needs to be
-+ deleted too.
-+
-+ * Starting cleanup: defined state names in order to get rid of
-+ the state numbers.
-+
-+2005-03-08 Markus Klotzbuecher <mk@chasey>
-+
-+ * Makefile fix, fist_ioctl was built against wrong sources if ARCH=um
-+
-+ * Fixed a bug in dentry.c, mini_fo_d_hash. In state 4 =
-+ DEL_REWRITTEN the hash was calculated from the base dentry,
-+ which was wrong and and caused assertions in
-+ __mini_fo_hidden_dentry to fail.
-+
-+2005-02-21 <mk@mary>
-+
-+ * Implemented directory deleting (inode.c)
-+
-+ * main.c: made mini_fo_parse_options a little more robust.
-+
-+2004-12-22 <mk@mary>
-+
-+ * Makefile cleanup and uml stuff, removed unneccessary files
-+
-+ * Created a new and hopefully more informative README
-+
-+ * CHANGELOG: created a new CHANGELOG and added old entries reversely
-+
-+
-+2004-10-24 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Fix: owner and group where not correctly copied from base to
-+ storage.
-+
-+
-+2004-10-05 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Implementation of fsync, fasync and lock mini_fo functions.
-+
-+
-+2004-09-29 Bob Lee <bob@pantasys.com>
-+
-+ * Fix of a serious pointer bug
-+
-+
-+2004-09-28 Gleb Natapov <gleb@nbase.co.il>
-+
-+ * Implementation of mini_fo_mknod and mini_fo_rename, support
-+ for device files.

-+README for the mini_fo overlay file system
-+=========================================
-+
-+
-+WHAT IS MINI_FO?
-+----------------
-+
-+mini_fo is a virtual kernel file system that can make read-only
-+file systems writable. This is done by redirecting modifying operations
-+to a writeable location called "storage directory", and leaving the
-+original data in the "base directory" untouched. When reading, the
-+file system merges the modifed and original data so that only the
-+newest versions will appear. This occurs transparently to the user,
-+who can access the data like on any other read-write file system.
-+
-+Base and storage directories may be located on the same or on
-+different partitions and may be of different file system types. While
-+the storage directory obviously needs to be writable, the base may or
-+may not be writable, what doesn't matter as it will no be modified
-+anyway.
-+
-+
-+WHAT IS GOOD FOR?
-+-----------------
-+
-+The primary purpose of the mini_fo file system is to allow easy
-+software updates to embedded systems, that often store their root
-+file system in a read-only flash file system, but there are many
-+more as for example sandboxing, or for allowing live-cds to
-+permanently store information.
-+
-+
-+BUILDING
-+--------
-+This should be simple. Adjust the Makefile to point to the correct
-+kernel headers you want to build the module for. Then:
-+
-+ # make
-+
-+should build "mini_fo.o" for a 2.4 kernel or "mini_fo.ko" for a 2.6
-+kernel.
-+
-+If you are building the module for you current kernel, you can install
-+the module (as root):
-+
-+ # make install
-+
-+or uninstall with
-+
-+ # make uninstall
-+
-+
-+USING THE FILE SYSTEM
-+--------------------
-+
-+the general mount syntax is:
-+
-+ mount -t mini_fo -o base=<base directory>,sto=<storage directory>\
-+ <base directory> <mount point>
-+
-+Example:
-+
-+You have mounted a cdrom to /mnt/cdrom and want to modifiy some files
-+on it:
-+
-+load the module (as root)
-+
-+ # insmod mini_fo.o for a 2.4 kernel or
-+
-+ # insmod mini_fo.ko for a 2.6 kernel
-+
-+
-+create a storage dir in tmp and a mountpoint for mini_fo:
-+
-+ # mkdir /tmp/sto
-+ # mkdir /mnt/mini_fo
-+
-+and mount the mini_fo file system:
-+
-+ # mount -t mini_fo -o base=/mnt/cdrom,sto=/tmp/sto /mnt/cdrom /mnt/mini_fo
-+
-+
-+Now the data stored on the cd can be accessed via the mini_fo
-+mountpoint just like any read-write file system, files can be modified
-+and deleted, new ones can be created and so on. When done unmount the
-+file system:
-+
-+ # unmount /mnt/mini_fo
-+
-+Note that if the file system is mounted again using the same storage
-+file system, of course it will appear in the modified state again. If
-+you remount it using an new empty storage directory, it will be
-+unmodified. Therefore by executing:
-+
-+ # cd /tmp/sto
-+ # rm -rf *
-+
-+you can nuke all the changes you made to the original file system. But
-+ remember NEVER do this while the mini_fo file system is mounted!
-+
-+
-+Alternatively you can use the mini_fo-overlay bash script, that
-+simplifies managing mini_fo mounts. See TOOLS Section.
-+
-+
-+TOOLS
-+-----
-+
-+mini_fo-merge (experimental):
-+
-+This is a bash script that will merge changes contained in the storage
-+directory back to the base directory. This allows mini_fo to function
-+as a cache file system by overlaying a slow (network, ...) file system
-+and using a fast (ramdisk, ...) as storage. When done, changes can be
-+merged back to the (slow) base with mini_fo-merge. See "mini_fo-merge
-+-h" for details.
-+
-+It can be usefull for merging changes back after a successfull test
-+(patches, software updates...)
-+
-+
-+mini_fo-overlay:
-+
-+This bash script simplifies managing one or more mini_fo mounts. For
-+overlaying a directory called "basedir1", you can just call:
-+
-+ # mini_fo-overlay basedir1
-+
-+This will mount mini_fo with "basedir1" as base, "/tmp/sto-basedir1/"
-+as storage to "/mnt/mini_fo-basedir1/". It has more options though,
-+type "mini_fo-overlay -h" for details.
-+
-+
-+DOCUMENTATION, REPORTING BUGS, GETTING HELP
-+-------------------------------------------
-+
-+Please visit the mini_fo project page at:
-+
-+http://www.denx.de/twiki/bin/view/Know/MiniFOHome
-+
-+
-+WARNINGS
-+--------
-+
-+Never modify the base or the storage directorys while the mini_fo
-+file system is mounted, or you might crash you system. Simply accessing
-+and reading should not cause any trouble.
-+
-+Exporting a mini_fo mount point via NFS has not been tested, and may
-+or may not work.
-+
-+Check the RELEASE_NOTES for details on bugs and features.

-+Date: 21.09.2005
-+
-+
-+Changes:
-+--------
-+v0-6-1:
-+
-+- bugfixes (see ChangeLog)
-+
-+- two helper scripts "mini_fo_merge" and "mini_fo_overlay" (see
-+ README for details).
-+
-+v0-6-0:
-+
-+- Support for 2.4 and 2.6 (see Makefile)
-+
-+- Partial hard link support (creating works as expected, but already
-+ existing links in the base file system will be treated as if they
-+ were individual files).
-+
-+- Various bugfixes and cleanups.
-+
-+
-+v0-6-0-pre1:
-+
-+- This is mini_fo-0-6-0-pre1! This release is a complete rewrite of
-+ many vital mini_fo parts such as the old whiteout list code which
-+ has been replaced by the new META subsystem.
-+
-+- Light weight directory renaming implemented. This means if a
-+ directory is renamed via the mini_fo filesystem this will no longer
-+ result in a complete copy in storage, instead only one empty
-+ directory will be created. All base filed contained in the original
-+ directory stay there until modified.
-+
-+- Special files (creating, renaming, deleting etc.) now working.
-+
-+- Many bugfixes and cleanup, mini_fo is now a lot more stable.
-+
-+
-+v0-5-10:
-+
-+- Final release of the 0-5-* versions. Next will be a complete rewrite
-+ of many features. This release contains several bugfixes related to
-+ directory renaming.
-+
-+
-+v0-5-10-pre6:
-+
-+- Lots of cleanup and several bugfixes related to directory deleting
-+
-+- Directory renaming suddenly works, what is most likely due to the
-+ fact tha that "mv" is smart: if the classic rename doesn't work it
-+ will assume that source and target file are on different fs and will
-+ copy the directory and try to remove the source directory. Until
-+ directory removing wasn't implemented, it would fail to do this and
-+ rollback.
-+ So, directory renaming works for now, but it doesn't yet do what you
-+ would expect from a overlay fs, so use with care.
-+
-+
-+v0-5-10-pre5:
-+
-+- implemented directory deleting
-+- made parsing of mount options more stable
-+- New format of mount options! (See README)
-+- I can't reproduce the unknown panic with 2.4.25 anymore, so I'll
-+ happily assume it never existed!
-+
-+
-+Implemented features:
-+---------------------
-+
-+- creating hard links (see BUGS on already existing hard links)
-+- lightweight directory renaming
-+- renaming device files, pipes, sockets, etc.
-+- creating, renaming, deleting of special files
-+- deleting directorys
-+- general directory reading (simple "ls" )
-+- creating files in existing directorys
-+- creating directorys
-+- renaming files.
-+- reading and writing files (involves opening)
-+- appending to files (creates copy in storage)
-+- deleting files
-+- llseek works too, what allows editors to work
-+- persistency (a deleted file stay deleted over remounts)
-+- use of symbolic links
-+- creating of device files
-+
-+
-+Not (yet) implemented features:
-+-------------------------------
-+
-+- full hard link support.
-+
-+
-+
-+BUGS:
-+-----
-+
-+Hard links in the base file system will be treated as individual
-+files, not as links to one inode.
-+
-+The main problem with hard links isn't allowing to create them, but
-+their pure existence. If you modify a base hard link, the changes made
-+will only show up on this link, the other link will remain in the
-+original state. I hope to fix this someday. Please note that this does
-+not effect the special hard links '.' and '..', that are handled
-+seperately by the lower fs.

-HSO: add option hso driver
-
-This driver is for a number of different Option devices. Originally
-written by Option and Andrew Bird, but cleaned up massivly for
-acceptance into mainline by me and others.
-
-Many thanks to the following for their help in cleaning up the driver by
-providing feedback and patches to it:
- - Paulius Zaleckas <paulius.zaleckas@teltonika.lt>
- - Oliver Neukum <oliver@neukum.org>
- - Alan Cox <alan@lxorguk.ukuu.org.uk>

-+GPIOMMC - Driver for an MMC/SD card on a bitbanging GPIO SPI bus
-+================================================================
-+
-+The gpiommc module hooks up the mmc_spi and spi_gpio modules for running an
-+MMC or SD card on GPIO pins.
-+
-+Two interfaces for registering a new MMC/SD card device are provided:
-+A static platform-device based mechanism and a dynamic configfs based interface.
-+
-+
-+Registering devices via platform-device
-+=======================================
-+
-+The platform-device interface is used for registering MMC/SD devices that are
-+part of the hardware platform. This is most useful only for embedded machines
-+with MMC/SD devices statically connected to the platform GPIO bus.
-+
-+The data structures are declared in <linux/mmc/gpiommc.h>.
-+
-+To register a new device, define an instance of struct gpiommc_platform_data.
-+This structure holds any information about how the device is hooked up to the
-+GPIO pins and what hardware modes the device supports. See the docbook-style
-+documentation in the header file for more information on the struct fields.
-+
-+Then allocate a new instance of a platform device by doing:
-+
-+ pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id());
-+
-+This will allocate the platform device data structures and hook it up to the
-+gpiommc driver.
-+Then add the gpiommc_platform_data to the platform device.
-+
-+ err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data));
-+
-+You may free the local instance of struct gpiommc_platform_data now. (So the
-+struct may be allocated on the stack, too).
-+Now simply register the platform device.
-+
-+ err = platform_device_add(pdev);
-+
-+Done. The gpiommc probe routine will be invoked now and you should see a kernel
-+log message for the added device.
-+
-+
-+Registering devices via configfs
-+================================
-+
-+MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example
-+selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded
-+hardware are a common situation.
-+So we provide a dynamic interface to conveniently handle adding and removing
-+devices from userspace, without the need to recompile the kernel.
-+
-+The "gpiommc" subdirectory at the configfs mountpoint is used for handling
-+the dynamic configuration.
-+
-+To create a new device, it must first be allocated with mkdir.
-+The following command will allocate a device named "my_mmc":
-+ mkdir /config/gpiommc/my_mmc
-+
-+There are several configuration files available in the new
-+/config/gpiommc/my_mmc/ directory:
-+
-+gpio_data_in = The SPI data-IN GPIO pin number.
-+gpio_data_out = The SPI data-OUT GPIO pin number.
-+gpio_clock = The SPI Clock GPIO pin number.
-+gpio_chipselect = The SPI Chipselect GPIO pin number.
-+gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH.
-+ If 1, Chipselect is active-LOW.
-+spi_mode = The SPI data mode. Can be 0-3.
-+spi_delay = Enable all delays in the lowlevel bitbanging.
-+max_bus_speed = The maximum SPI bus speed. In Hertz.
-+
-+register = Not a configuration parameter.
-+ Used to register the configured card
-+ with the kernel.
-+
-+The device must first get configured and then registered by writing "1" to
-+the "register" file.
-+The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock"
-+and "gpio_chipselect" are essential and _must_ be configured before writing
-+"1" to the "register" file. The registration will fail, otherwise.
-+
-+The default values for the other parameters are:
-+gpio_chipselect_activelow = 1 (CS active-LOW)
-+spi_mode = 0 (SPI_MODE_0)
-+spi_delay = 1 (enabled)
-+max_bus_speed = 5000000 (5 Mhz)
-+
-+Configuration values can not be changed after registration. To unregister
-+the device, write a "0" to the "register" file. The configuration can be
-+changed again after unregistering.
-+
-+To completely remove the device, simply rmdir the directory
-+(/config/gpiommc/my_mmc in this example).
-+There's no need to first unregister the device before removing it. That will
-+be done automatically.

-A similar patch for ppc64 made it upstream with your big ppc64 merge.
-This one is still sitting in http://patchwork.ozlabs.org/linuxppc/

-Subject: gpio: sysfs interface
-X-Git-Tag: v2.6.27-rc1~449
-X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=d8f388d8dc8d4f36539dd37c1fff62cc404ea0fc

-gpio: sysfs interface
-
-This adds a simple sysfs interface for GPIOs.
-
- /sys/class/gpio
- /export ... asks the kernel to export a GPIO to userspace
- /unexport ... to return a GPIO to the kernel
- /gpioN ... for each exported GPIO #N
- /value ... always readable, writes fail for input GPIOs
- /direction ... r/w as: in, out (default low); write high, low
- /gpiochipN ... for each gpiochip; #N is its first GPIO
- /base ... (r/o) same as N
- /label ... (r/o) descriptive, not necessarily unique
- /ngpio ... (r/o) number of GPIOs; numbered N .. N+(ngpio - 1)
-
-GPIOs claimed by kernel code may be exported by its owner using a new
-gpio_export() call, which should be most useful for driver debugging.
-Such exports may optionally be done without a "direction" attribute.
-
-Userspace may ask to take over a GPIO by writing to a sysfs control file,
-helping to cope with incomplete board support or other "one-off"
-requirements that don't merit full kernel support:
-
- echo 23 > /sys/class/gpio/export
- ... will gpio_request(23, "sysfs") and gpio_export(23);
- use /sys/class/gpio/gpio-23/direction to (re)configure it,
- when that GPIO can be used as both input and output.
- echo 23 > /sys/class/gpio/unexport
- ... will gpio_free(23), when it was exported as above
-
-The extra D-space footprint is a few hundred bytes, except for the sysfs
-resources associated with each exported GPIO. The additional I-space
-footprint is about two thirds of the current size of gpiolib (!). Since
-no /dev node creation is involved, no "udev" support is needed.
-
-Related changes:
-
- * This adds a device pointer to "struct gpio_chip". When GPIO
- providers initialize that, sysfs gpio class devices become children of
- that device instead of being "virtual" devices.
-
- * The (few) gpio_chip providers which have such a device node have
- been updated.
-
- * Some gpio_chip drivers also needed to update their module "owner"
- field ... for which missing kerneldoc was added.
-
- * Some gpio_chips don't support input GPIOs. Those GPIOs are now
- flagged appropriately when the chip is registered.
-
-Based on previous patches, and discussion both on and off LKML.
-
-A Documentation/ABI/testing/sysfs-gpio update is ready to submit once this
-merges to mainline.

-+once all the necessary resources are available, and remove them later when

-+
-+
-+Sysfs Interface for Userspace (OPTIONAL)
-+========================================
-+Platforms which use the "gpiolib" implementors framework may choose to
-+configure a sysfs user interface to GPIOs. This is different from the
-+debugfs interface, since it provides control over GPIO direction and
-+value instead of just showing a gpio state summary. Plus, it could be
-+present on production systems without debugging support.
-+
-+Given approprate hardware documentation for the system, userspace could
-+know for example that GPIO #23 controls the write protect line used to
-+protect boot loader segments in flash memory. System upgrade procedures
-+may need to temporarily remove that protection, first importing a GPIO,
-+then changing its output state, then updating the code before re-enabling
-+the write protection. In normal use, GPIO #23 would never be touched,
-+and the kernel would have no need to know about it.
-+
-+Again depending on appropriate hardware documentation, on some systems
-+userspace GPIO can be used to determine system configuration data that
-+standard kernels won't know about. And for some tasks, simple userspace
-+GPIO drivers could be all that the system really needs.
-+
-+Note that standard kernel drivers exist for common "LEDs and Buttons"
-+GPIO tasks: "leds-gpio" and "gpio_keys", respectively. Use those
-+instead of talking directly to the GPIOs; they integrate with kernel
-+frameworks better than your userspace code could.
-+
-+
-+Paths in Sysfs
-+--------------
-+There are three kinds of entry in /sys/class/gpio:
-+
-+ - Control interfaces used to get userspace control over GPIOs;
-+
-+ - GPIOs themselves; and
-+
-+ - GPIO controllers ("gpio_chip" instances).
-+
-+That's in addition to standard files including the "device" symlink.
-+
-+The control interfaces are write-only:
-+
-+ /sys/class/gpio/
-+
-+ "export" ... Userspace may ask the kernel to export control of
-+ a GPIO to userspace by writing its number to this file.
-+
-+ Example: "echo 19 > export" will create a "gpio19" node
-+ for GPIO #19, if that's not requested by kernel code.
-+
-+ "unexport" ... Reverses the effect of exporting to userspace.
-+
-+ Example: "echo 19 > unexport" will remove a "gpio19"
-+ node exported using the "export" file.
-+
-+GPIO signals have paths like /sys/class/gpio/gpio42/ (for GPIO #42)
-+and have the following read/write attributes:
-+
-+ /sys/class/gpio/gpioN/
-+
-+ "direction" ... reads as either "in" or "out". This value may
-+ normally be written. Writing as "out" defaults to
-+ initializing the value as low. To ensure glitch free
-+ operation, values "low" and "high" may be written to
-+ configure the GPIO as an output with that initial value.
-+
-+ Note that this attribute *will not exist* if the kernel
-+ doesn't support changing the direction of a GPIO, or
-+ it was exported by kernel code that didn't explicitly
-+ allow userspace to reconfigure this GPIO's direction.
-+
-+ "value" ... reads as either 0 (low) or 1 (high). If the GPIO
-+ is configured as an output, this value may be written;
-+ any nonzero value is treated as high.
-+
-+GPIO controllers have paths like /sys/class/gpio/chipchip42/ (for the
-+controller implementing GPIOs starting at #42) and have the following
-+read-only attributes:
-+
-+ /sys/class/gpio/gpiochipN/
-+
-+ "base" ... same as N, the first GPIO managed by this chip
-+
-+ "label" ... provided for diagnostics (not always unique)
-+
-+ "ngpio" ... how many GPIOs this manges (N to N + ngpio - 1)
-+
-+Board documentation should in most cases cover what GPIOs are used for
-+what purposes. However, those numbers are not always stable; GPIOs on
-+a daughtercard might be different depending on the base board being used,
-+or other cards in the stack. In such cases, you may need to use the
-+gpiochip nodes (possibly in conjunction with schematics) to determine
-+the correct GPIO number to use for a given signal.
-+
-+
-+Exporting from Kernel code
-+--------------------------
-+Kernel code can explicitly manage exports of GPIOs which have already been
-+requested using gpio_request():
-+
-+ /* export the GPIO to userspace */
-+ int gpio_export(unsigned gpio, bool direction_may_change);
-+
-+ /* reverse gpio_export() */
-+ void gpio_unexport();
-+
-+After a kernel driver requests a GPIO, it may only be made available in
-+the sysfs interface by gpio_export(). The driver can control whether the
-+signal direction may change. This helps drivers prevent userspace code
-+from accidentally clobbering important system state.
-+
-+This explicit exporting can help with debugging (by making some kinds
-+of experiments easier), or can provide an always-there interface that's
-+suitable for documenting as part of a board support package.
