[Cosmin Tanislav]

V1 -> V2
 * sign off using company email

V2 -> V3
 * replace gpo config firmware flag with one flag specifying whether gpo is in
   comparator mode
 * create two separate gpiochips, one output-only for GPO pins not in
   comparator mode and one input-only for the value of digital input channels
 * wire up all gpo functionalities using pinconf
 * keep number of characters per line under 80
 * rework locking
 * do not invalidate other chip revisions
 * do not set indio device parent
 * print probe error for refin regulator
 * move conversion from range register value to range / offset / raw offset
   into separate function
 * module.h -> mod_devicetable.h
 * use generic firmware interface functions
 * add comment regarding cache alignment
 * add comment regarding ADC channels buffered read setup
 * un-inline comment regarding 100us delay for conversion start
 * inline return statements
 * remove assignments to val2 where not necessary
 * local_channels -> chans
 * index -> i
 * channel_config -> config
 * IIO_ALTVOLTAGE -> IIO_VOLTAGE
 * .info_mask_shared_by_type_available -> .info_mask_separate_available
 * remove unlikely probe error messages
 * use an array indexed by channel function for retrieving iio channels
 * count iio channels while parsing
 * move HART rate rejection outside of setter
 * move channel function validation outside of setter
 * use SPI messages for read and write
 * validate DAC code earlier
 * simplify switches to only handle existing iio channels
 * pass indio_dev into functions needing access to it
 * pass spi into devm_regmap_init
 * dt-bindings: sort compatibles
 * dt-bindings: remove driver word from description
 * dt-bindings: remove refin supply description
 * dt-bindings: specify channel function default value
 * dt-bindings: remove maxItems from scalar value
