For the PLX local address space range registers, LAS0RR and LAS1RR, bit
0 indicates whether the local address space will be mapped to memory
space or I/O space. If mapped to I/O space, bit 1 must be set to 0, and
bits 31 to 2 form the address decoding mask, which should be -2^N mod
2^32 for a range of length 2^N.
The `LRNG_IO_MASK` macro is supposed to specify the address decoding
bits for I/O space. It currently has the value `0xfffffffa`, but should
be `0xfffffffc`, or possibly `0xfffffffe` (it doesn't really matter,
since bit 1 is required to be set to 0). Change it to `0xfffffffc`.
Similarly, for the PLX local address space local base address (remap)
registers, LAS0BA and LAS1BA, bits 31 to 2, masked with the
corresponding "range" register form the local base address for the local
address space. The `LMAP_IO_MASK` macro is supposed to mask the valid

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
the analog inputs.

The analog inputs are confgured with jumpers on the board to be:
* 16 single-ended inputs
* 8 differential inputs
* 16 pseudo-differential inputs (common ground)
Simplify the handling of this configuration option and properly set
the subdev_flags based on the selected input mode.

staging: comedi: dt2811: simplify analog output range options
The D/A ranges are not programmable. Currently this driver uses some
configuration options to select the comedi_lrange for each channel.
This is a bit messy and it requires the user to make sure the correct
option value is used.
The range information isn't used by the driver. The user space library
uses it to convert between raw data values and physical units. If the
user passed an incorrect option when attaching the driver the conversion
will be incorrect.
Simplify the analog output ranges by providing a range_table that
contains all the possible output ranges. The user can then select the
correct range when converting values.

staging: lustre: hide call to Posix ACL in ifdef
A call to forget_cached_acl() was recently added to the lustre file
system, but this is only available when CONFIG_FS_POSIX_ACL is
enabled, otherwise the build now fails with:
lustre/llite/file.c: In function 'll_get_acl':
lustre/llite/file.c:3134:2: error: implicit declaration of function 'forget_cached_acl' [-Werror=implicit-function-declaration]
forget_cached_acl(inode, type);
This adds one more #ifdef for this call, corresponding to the
other 22 such checks for ACL in lustre.

staging: lustre: llite: remove lloop device
The lloop device was original developed to work around
the lack of direct I/O for the default loop back device.
Also the lloop device greatly out performed the default
loop back device. The lloop hasn't been worked on for
some time and now it no longer out performs the loop
device and loop now supports direct I/O. Since this is
the case we can delete this device.

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.
