d5d8f49b63 max44000: Expose ambient sensor scaling
This patch exposes ALSTIM as illuminance_integration_time and ALSPGA as
illuminance_scale.

Changing ALSTIM also changes the number of bits available in the data
register. This is handled inside raw value reading because:
* It's very easy to shift a few bits
* It allows SCALE and INT_TIME to be completely independent controls
* Buffer support requires constant scan_type.realbits per-channel

237a378b3b max44000: Support controlling LED current output
This is exposed as an output channel with "led" as an extend_name.

Other sensors also have support for controlling an external LED. It's
not clear that simply exposing an undecorated output channel is the
correct approach.

dfc57732ad iio:core: mounting matrix support
Expose a rotation matrix to indicate userspace the chip placement with
respect to the overall hardware system. This is needed to adjust
coordinates sampled from a sensor chip when its position deviates from the
main hardware system.

Final coordinates computation is delegated to userspace since:
* computation may involve floating point arithmetics ;
* it allows an application to combine adjustments with arbitrary
  transformations.

This 3 dimentional space rotation matrix is expressed as 3x3 array of
strings to support floating point numbers. It may be retrieved from a
"[<dir>_][<type>_]mount_matrix" sysfs attribute file. It is declared into a
device / driver specific DTS property or platform data.

efc2c0133f iio: core: Add devm_ APIs for iio_channel_{get,release}_all
Some of kernel driver uses the IIO framework to get the sensor
value via ADC or IIO HW driver. The client driver get iio channel
by iio_channel_get_all() and release it by calling
iio_channel_release_all().

Add resource managed version (devm_*) of these APIs so that if client
calls the devm_iio_channel_get_all() then it need not to release it
explicitly, it can be done by managed device framework when driver
get un-binded.

This reduces the code in error path and also need of .remove callback in

0e6f6871a1 iio: st_sensors: support open drain mode
Some types of ST Sensors can be connected to the same IRQ line
as other peripherals using open drain. Add a device tree binding
and a sensor data property to flip the right bit in the interrupt
control register to enable open drain mode on the INT line.

If the line is set to be open drain, also tag on IRQF_SHARED
to the IRQ flags when requesting the interrupt, as the whole
point of using open drain interrupt lines is to share them with
more than one peripheral (wire-or).

97865fe413 iio: st_sensors: verify interrupt event to status
This makes all ST sensor drivers check that they actually have
new data available for the requested channel(s) before claiming
an IRQ, by reading the status register (which is conveniently
the same for all ST sensors) and check that the channel has new
data before proceeding to read it and fill the buffer.

This way sensors can share an interrupt line: it can be flaged
as shared and then the sensor that did not fire will return
NO_IRQ, and the sensor that fired will handle the IRQ and
return IRQ_HANDLED.

6436db37b4 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.

- No weird custom power management from userspace
- No homebrewn values in sysfs

This uses the same (undocumented) device tree compatible-string

eb7bfed901 First round of IIO new device support, features and cleanups for the 4.7 cycle.
New core support
 * UV light modifier (for intensity)
 * UV light index channel type.
 
 New device support
 * hp206c barometer and altimeter
   - new driver.
 * mcp4131 potentiometer
   - new driver supporting lots of parts from Microchip.
 * mma8452
   - FXLS8471Q support
 - NXP LPC18XX SOC ADC
   - new driver.
 - NXP LPC18XX SOC DAC
   - new driver.
 - rockchip_saradc
   - support rk3399
 * st accel
   - h3lis331dl support
 
 Staging driver removals
 * adis16204
   - obsolete part making it hard to get parts to test the driver in order
     to clean it up.
 * adis16220
   - obsolete part making it hard to get the parts test the driver in order
     to clean it up.
 
 Features
 * core
   - convenience functions to claim / release direct access to the device.
     Makes more consistent handling of this corner easier. Used in ad7192 driver.
 * ak8975
   - power regulator support.
 * at91-sama5d2
   - differential channel support.
 * mma8452
   - runtime pm support
   - drop device specific autosleep and use the runtime pm one instead.
 * ms5611
   - DT bindings
   - oversampling ratio support
 
 Cleanups and minor fixes
 * MAINTAINERS
   - Peter got married - hence name change!
 
 * Documentation
   - Fix a typo in in_proximity_raw description.
   - Add some missing docs for iio_buffer_access_funcs.
 
 * Tools
   - update iio_event_monitor names to match new stuff.
   - make generic_buffer look for triggers ending in -trigger as we let these in
   for a number of drivers a long time back and now it is a fairly common
   option.
 
 Drivers
 * staging wide
   - convert bare unsigned usage to unsigned int to comply with coding style.
 * non staging wide:
   - since boiler plate gpio handling of interrupts has been moved into the
    ACPI core we don't need to include gpio/consumer.h in a load of drivers so
    drop it.
 * ad7606
   - fix an endian casting sparse warning.
 * ak8975
   - fix a possible unitialized warning from gcc.
   - drop and unused field left over from earlier cleanups
   - fix a missing regulator_disable on exit.
 * at91-sama5d2
   - typo and indentation
   - missing IOMEM dependency.
   - cleanup mode register usage by avoidling erasing whole thing when changing
   the sampling frequency.
 * bmc150
   - use the core demux and available_scan_masks to simplify buffer handling
   - optimize the transfers in the trigger handler now we have a magic function
   to emulate bulk reads (under circumstances met here).  This matters with some
   rather dumb i2c adapters in particular.
   - use a single regmap_conf for all bus types as they were all the same.
 * bmg160
   - use the core demux and available_scan_masks to simplify the buffer handling
   - optimize the transfers in the trigger handler now we have a magic funciton
   to emulate bulk rads (under circumstances met here).
   - drop gpio interrupt probing from the driver (ACPI) as now handled by the
   ACPI core.
 * ina2xx-adc
   - update the CALIB register when RShunt changes.
   - fix scale for VShunt - in reality this error canceled out when used.
 * isl29028
   - use regmap to retrieve the struct device instead of carrying a second
   copy of it around.
 * kxcjk-1013
   - use core demux
   - optimize i2c transfers in the trigger handler.
 * mcp4531
   - refactor to use a pointer to access model parameters instead of indexing
     into the array each time.
 * mma8452
   - style fixes
   - avoid swtiching to active whenever the config changes
   - add missin i2c_device_id for mma8451
 * mpu6050
   - fix possible NULL dereference.
   - fix the name / chip_id used when ACPI used (otherwise reports as NULL).
 * ms5611
   - fix a missing regulator_disable that left the regulator on during removal.
 * mxc4005
   - drop gpio interrupt handling for ACPI case from driver as the core now
   handles this case.
 * st-sensors
   - note that there are only ever a maximum of 3 axis on current st-sensors
   so just allocate a fixed sized buffer big enough for that.
 * tpl0102
   - change the i2c_check_functionality condition to bring it inline with other
     IIO users as EOPNOTSUPP.
 * tsl2563
   - replace deprecated flush_scheduled_work

486294f184 iio: accel: bmc150: use common definition for regmap conf
bmc150_i2c_regmap_conf is defined three times (in bmc150-accel-core.c,
bmc150-accel-i2c.c and and bmc150-accel-spi.c), although the
definition is the same.

Use one common definition for bmc150_i2c_regmap_conf in all
included files.
