Greg Kroah-Hartman 552edf8d79 Second set of iio new device support, features and cleanups for the 4.9 cycle. 
New device support
 * ad8801 dac
   - new driver supporting ad8801 and ad8803 DACs.
 * adc12138
   - new driver supporting TI adc12130/adc12132 and adc12138 ADCs.
 * ltc2485 adc
   - new driver
 * mxc6255
   - add support for the mxc6225 part name and fixup the ID check so it works.
 * vz89x VOC sensor
   - add support for the vz89te part which drops the voc_short channel and adds
     CRCs compared to other supported parts.
 
 New features
 * core
   - immutable triggers.  These effectively grant exclusive control over a
     trigger. The typical usecase is a device representing an analog part
     (perhaps a MUX) that needs to control the sampling of a downstream
     ADC.
   - resource managed trigger registration and triggered_buffer_init.
   - iio_push_event now protected against case of the event interface
     registration not having yet occured.  Only matters if an interrupt
     can occur during this window - might happen on shared interrupt lines.
   - helper to let a driver query if the trigger it is using is provided by
     itself (using the convention of both device and trigger having the same
     parent).
 * tools
   - iio-utils. Used channel modifier scaling in preference to generic scaling
     when both exist.
 * at91-adc
   - Add support for touchscreen switches closure time needed by some newer
     parts.
 * stx104
   - support the ADC channels on this ADC/DAC board. As these are the primary
     feature of the board also move the driver to the iio/adc directory.
 * sx9500
   - device tree bindings.
 
 Cleanups / Fixes
 * ad5755
   - fix an off-by-one on devnr limit check (introduced earlier this cycle)
 * ad7266
   - drop NULL check on devm_regulator_get_optional as it can't return NULL.
 * ak8974
   - avoid an unused functional warning due to rework in PM core code.
   - remove .owner field setting as done by i2c_core.
 * ina2xx
   - clear out a left over debug field from chip global data.
 * hid-sensors
   - avoid an unused functional warning due to rework in PM core code.
 * maxim-thermocouple
   - fix non static symbol warnings.
 * ms5611
   - fetch and enable regulators unconditionally when they aren't optional.
 * sca3000
   - whitespace cleanup.
 * st_sensors
   - fetch and enable regulators unconditionally rather than having them
     supported as optional regulators (missunderstanding on my part amongst
     others a while back)
   - followup to previous patch fixes error checking on the regulators.
   - mark symbols static where possible.
   - use the 'is it my trigger' help function.  This prevents the odd case
     of another device triggering from the st-sensors trigger whilst the
     st-sensors trigger is itself not using it but rather using say an hrtimer.
 * ti-ads1015
   - add missing of_node_put.
 * vz89x
   - rework to all support of new devices.
   - prevent reading of a corrupted buffer.
   - fixup a return value of 0/1 in a bool returning function.

This driver can also be built as a module. If so, the module will be
called twl4030-madc.

Say yes here if you want support for the TWL6030/TWL6032 General
Purpose A/D Converter. This will add support for battery type
detection, battery voltage and temperature measurement, die
temperature measurement, system supply voltage, audio accessory,
USB ID detection.
This driver can also be built as a module. If so, the module will be
called twl6030-gpadc.

Say yes here to support for Vybrid board analog-to-digital converter.
Since the IP is used for i.MX6SLX, the driver also support i.MX6SLX.
This driver can also be built as a module. If so, the module will be
called vf610_adc.

help
Say yes here to access the ADC part of the Nano River
Technologies Viperboard.
To compile this driver as a module, choose M here: the module will be
called viperboard_adc.

help
Say yes here to have support for the Xilinx XADC. The driver does support
both the ZYNQ interface to the XADC as well as the AXI-XADC interface.
The driver can also be build as a module. If so, the module will be called
xilinx-xadc.
