iio: adc: nau7802: Expose possible gains in sysfs
The Nuvoton NAU7802 ADC is able to adjust its gain but prior knowledge of
its possible values was required to adjust it. Users had to guess the
possible gain values based on the ADC datasheet or on this driver's code.
This exposes the possible values in the in_voltage_scale_available file of
each nau7802 ADC device. The gain is set for the whole ADC and is therefore
not configurable by channel. Thus, there exists only one
in_voltage_scale_available file for each nau7802 ADC device even if it has
two separate channels.

and a sensor data property to flip the right bit in the interrupt

If the line is set to be open drain, also tag on IRQF_SHARED

point of using open drain interrupt lines is to share them with
more than one peripheral (wire-or).

iio: st_sensors: read each channel individually
The current buffer read code tries to optimize reads from the
sensor data registers by issuing a single read operation across
all the indata registers.
This doesn't work: when the LIS331DL accelerometer sensor is
configured to open drain, active low interrupt mode, this will
just clear the XDA (X-axis data available) bit in the STATUS_REG
register (0x27), while YDA, ZDA and even ZYXDA remain set to 1,
and the internal logic of the sensor holds the DRDY (INT1) line
asserted (the value of the status register is 0xee).
If we instead issue one read operation per enabled channel
(X, Y, Z) things start working and we can use open drain and
active low interrupts.
Note that a backported patch fixing this issue will be heading
via the fixes branch but changes in this file already in staging-next
will make that patch 'look' rather different. The code in here
is the correct one when that clash hits.

android,lowmemorykiller: Don't abuse TIF_MEMDIE.
Currently, lowmemorykiller (LMK) is using TIF_MEMDIE for two purposes.
One is to remember processes killed by LMK, and the other is to
accelerate termination of processes killed by LMK.
But since LMK is invoked as a memory shrinker function, there still
should be some memory available. It is very likely that memory
allocations by processes killed by LMK will succeed without using
ALLOC_NO_WATERMARKS via TIF_MEMDIE. Even if their allocations cannot
escape from memory allocation loop unless they use ALLOC_NO_WATERMARKS,
lowmem_deathpending_timeout can guarantee forward progress by choosing
next victim process.
On the other hand, mark_oom_victim() assumes that it must be called with
oom_lock held and it must not be called after oom_killer_disable() was
called. But LMK is calling it without holding oom_lock and checking
oom_killer_disabled. It is possible that LMK calls mark_oom_victim()
due to allocation requests by kernel threads after current thread
returned from oom_killer_disabled(). This will break synchronization
for PM/suspend.
This patch introduces per a task_struct flag for remembering processes
killed by LMK, and replaces TIF_MEMDIE with that flag. By applying this
patch, assumption by mark_oom_victim() becomes true.
