Rename the macros defining values for the DAC status register to avoid
CamelCase, and to make it clear which register they are associated with.
Refactor the macros defining the regular DAC channel "busy" bits into a
single macro that takes the DAC channel number as a parameter.

Add a macro to define the offset of the read-only DAC status register.
It is the same offset as the DAC control register, which is write-only.

The code in `daqboard2000_ao_eoc()` that checks the status for
completion of the DAC conversion looks wrong.  The register has a "busy"
bit for each channel, but the existing code only works for channels 0
and 1.  The driver only supports two DAC channels at the moment, so the
bug is currently harmless, but fix it so we can support four DAC
channels on some board models.

staging: comedi: dt2811: simplify analog input range options

The A/D ranges are not programmable but the gain is. Currently this driver
uses a configuration option to select the comedi_lrange that will be used
for the analog input subdevice. This requires that the user makes sure the
correct option value is used.

The user space library uses the range information to convert between raw
values and physical units. If the user passed an incorrect option when
attaching the driver the conversion will be incorrect.

A previous patch allowed the gain to be set based on the chanspec range.
Prior to that the gain was always set to 1 so any conversion with a gain
that is not 1 would be incorrect anyway.

Simplify the analog input ranges by providing a range_table for the pgh and
pgl boards that contain all the possible range/gain options. The user can
then select the correct range (and gain) when converting values or reading

staging: comedi: das16m1: remove unnecessary ai 'cancel' operations

The comedi core will only call the (*insn_read) and (*do_cmd) functions
if the subdevice is not "busy". All async commands are terminated by
a (*cancel) operation which clears the INTE and PACER_MASK bits in the
interrupt control register. These bits are also cleared when the driver
first attaches. There is no need for the (*insn_read) or (*do_cmd) to
duplicate the cancel.

Merge tag 'iio-for-4.8a' of git://git./linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First round of IIO new device support, features and cleanups for the 4.8 cycle.

New device support
* ads1015
  - add ads1115 support
* bma220 accelerometer
  - new driver
  - triggered buffer support.
* bmc150
  - add bmm150 support.
* bmp280
  - bme280 support with addition of humidity channel.
* max5487 potentiometer
  - new driver
* MMA7660FC accelerometer.
  - New driver
* st-pressure
  - support for the lps22hb
* loop trigger.
  - This one is *nasty* but we have real applications (parrot drones) where
  it is useful.  The trigger basically spins as hard as it can firing off
  a new trigger each time all triggered devices come back to say they are
  done.  It doesn't hang a machine even when doing it on a dummy driver.
  A lot nicer than having this implemented within lots of device drivers
  anyway.

Core stuff
* Add support to create IIO devices via configfs (similar to we did for
triggers a while back) + docs.
* New channel types
  - IIO_ELECTRICAL_CONDUCTIVITY
* Couple of MAINTAINERS patches to list the device tree bindings.
* Make trigger ops structure non optional (comment fix). It hasn't been for
an awful long time, but that's not what the description said.

New features
* ak8975
  - support adapters that are limited to byte data only by allowing the
  emulated block read i2c function that was recently introduced.
* atlas-ph
  - support atlas-ec (electrical conductivity sensor)
* bmi160
  - add available frequency and scale attributes to make the driver
  more user friendly (and avoid having to read the datasheet to know
  what will work).
* dummy
  - move creation to configfs interface.  It's not real hardware so we
  are not that worried about the ABI breakage ;)
* mma8452
  - oversampling ration support
* nau7802
  - expose available gains to make life easier for userspace.
* st-sensors
  - allow use of emulation for SMBus block reads as all the st parts support
  it.
* ti-ads1015
  - list datasheet names to allow their use by inkernel consumers.
* Various module alias additions to help auto probing.  Drop one redundant one
as well.

Cleanups
* ad7266, ad7476, ad7887, ad7923, ad799x
  - use direct mode claim function rather than open coding it during sensor
  read (prevents switching on buffers mid read).
* ad7793, ad7791
  - use direct mode claim to prevent frequency changes when buffers running.
* afe440x - These are ABI breaking but the driver requires custom userspace
  code to do anything useful anyway and that is still being written and under
  control of TI.  Ultimately we may have other libraries to do pulse
  oximetry with these devices but we aren't aware of any yet.
  - kernel-doc format fixes
  - drop ifdef fun around of_match_ptr - it's not worth the mess to save
  a tiny amount of space.
  - drop some unnecessary register initializations.
  - drop the weird locked gain modes as they gain us nothing (can just set
  all gains separately).
  - remove handling of offset attributes seeing as no channels actually have
  them (oops)
  - Drop the LED3 input channel as it's an alias for ALED2.
  - *big one* remove channel names - an experiment that turned out to not
  make sense - see patch for details.
  - use regmap fields to clean up code.
  - tie the tia gain stages to appropriate channels in the ABI as that is
  what they really effect. Same with the LED currents.
  - cleanout some unused defines and fix a missnamed one.
* atlas-ph
  - reorganise to allow support of other similar parts.
* bmc150
  - document supported chips in kconfig help.
* jsa1212
  - drop an unneeded i2c functionality check for functionality the driver
  doesn't use.
* mxs-lradc
  - simply touch screen registration code.
  - remove the touch screen unregister as all devm based now.
  - disable only those channels that are masked in hardware stop (others
  are already dealt with elsewhere)
* st-sensors
  - unexport st_sensors_get_buffer_element as nothing outside the st-sensors
  core driver uses it.
  - fix handling of failure to start up regulators.
* tpl0102
  - drop an i2c functionality test for features that aren't needed.
* ti-am335x
  - use variable name rather than type in sizeof for clarity.
  - use SIMPLE_DEV_PM_OPS helper macro to tidy up a bit.

Tools
* Add install / uninstall to makefile.  Someone cares, so presumably
some people will find it useful!
*  generic_buffer
   - rename to iio_generic_buffer to line up with other tools.
   - handle cleanup when receiving signals
   - Add a --device-num option and a --trigger-num option rather than
   relying on naming which doesn't work if you have two of the same part.

staging: unisys: visorhba: simplify and enhance debugfs interface

debugfs info for each visorhba device is now presented by a file named of
the following form within the debugfs tree:

    visorhba/vbus<x>:dev<y>/info

where <x> is the vbus number, and <y> is the relative device number.

Also, the debugfs presentation function was converted to use the seq_file
interface, so that it could access the device context without resorting to
a global array.  This also simplified the function.

staging: unisys: visorhba: remove unused (and broken) logic

The handling of CMD_NOTIFYGUEST_TYPE messages from the IO partition appears
to be only partially implemented, but fortunately it is never used in our
current environment.  This patch deletes the unused code.

staging: unisys: visorhba: correct scsi task mgmt completion handling

This patch is necessary to enable ANY task mgmt command to complete
successfully via visorhba.

When issuing a task mgmt command (CMD_SCSITASKMGMT_TYPE) to the IO
partition (back-end), forward_taskmgmt_command() includes pointers
within the command area that will be used to wake up the issuing
process and provide the result when the command completes:

    cmdrsp->scsitaskmgmt.notify_handle = (u64)&notifyevent;
    cmdrsp->scsitaskmgmt.notifyresult_handle = (u64)&notifyresult;

'notify_handle' is a pointer to a 'wait_queue_head_t' variable, and
'notifyresult' is a pointer to an int.  Both of these are just local
stack variables in the issuing process.

The way it's supposed to happen is that when the IO partition completes
the command, in our completion handling we get copies of those pointers
back from the IO partition, where we stash the result of the command at
'*notifyresult' (which should not be 0xffff, because that is the initial
value that the caller is looking to see a change in), and wake up the
wait queue at '*notify_handle'.  There are several places we do that dance,
but prior to this patch, we always do it WRONG, like:

    cmdrsp->scsitaskmgmt.notifyresult_handle = TASK_MGMT_FAILED;
    wake_up_all((wait_queue_head_t *)cmdrsp->scsitaskmgmt.notify_handle);

The wake_up_all() part is correct (albeit with the help of the sloppy
pointer casting, but that's irrelevant to the bug), but the assignment of
'notifyresult_handle' is WRONG, and SHOULD read:

    *(int *)(cmdrsp->scsitaskmgmt.notifyresult_handle) = TASK_MGMT_FAILED;

Without this change, the caller is NEVER going to notice a change in his
local value of 'notifyresult' when he does the:

    if (!wait_event_timeout(notifyevent, notifyresult != 0xffff,
                            msecs_to_jiffies(45000)))

and hence will be timing out EVERY taskmgmt command.

This patch also eliminates the need for sloppy casting of pointers
back-and-forth between u64 values, with the help of idr_alloc() to provide
handles for us.  It is the generated int handles we pass to the IO
partition to denote our completion context, and these are validated and
converted back to the required pointers when the task mgmt commands are
returned back to us by the IO partition.

== Testing ==

You must enable dynamic debugging in visorhba (build kernel with
'CONFIG_DYNAMIC_DEBUG=y', provide kernel parameter 'visorhba.dyndbg=+p')
to see kernel messages involved with visorhba scsi task mgmt commands,
which were added in this patch in the form of a few dev_dbg() / pr_debug()
messages.

In order to inject faults necessary to get visorhba to actully issue scsi
task mgmt commands, you will need to compile a kernel with
CONFIG_FAIL_IO_TIMEOUT and friends, in the "Kernel hacking" section:
* Enable "Fault-injection framework"
  * Enable "Fault-injection capability for disk IO"
  * Enable "Fault-injection capability for faking disk interrupts"
* Enable "Debugfs entries for fault-injection capabilities"

When running a kernel with those options, you can manually inject a fault
that will force a scsi task mgmt command to be issued like this:

    # mount -t debugfs nodev /sys/kernel/debug
    # cd /sys/kernel/debug/fail_io_timeout
    # cat interval
    1
    # cat probability
    0
    # cat times
    1
    # echo 100 >probability
    # cd /sys/block/sda
    # l | grep fail
    -rw-r--r--  1 root root 4096 May  5 10:53 io-timeout-fail
    -rw-r--r--  1 root root 4096 May  5 10:54 make-it-fail
    # echo 1 >io-timeout-fail
    # echo 1 >make-it-fail

To test this patch, after performing the above steps, I did something to
force a block device i/o, then shortly afterwards examined the kernel log.
There I found evidence that visorhba had successfully issued a task mgmt
command, and that it completed successfully:
