Subject: [PATCH v10 0/3] Add AD74413R driver
V1 -> V2
* sign off using company email
V2 -> V3
* replace gpo config firmware flag with flag specifying whether gpo is in
comparator mode
* create two separate gpiochips, one output-only gpiochip 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
V3 -> v4
* remove double gpo from macro name
* reset at probe
* config -> chip_info and store chip name inside chip info
* cacheline align every DMA buffer
* simplify generation of adc samples message by caching xfer, tx_buf and
rx_buf
* use mask itself for writing the value of channel enable and gpo data
* move reg read and write transfers to the same buffers and use local
variables for transfers
* merge the two for loops handling gpio configuration
* let firmware decide irq edge
* remove INDIO_BUFFER_SOFTWARE already set by iio framework
* do not set trigger device parent
* return dev_err_probe for regulator error case
* do not set cs_change to 0 when not needed
* do not set spi device drvdata as it is not needed
* fix bug regarding wrong channels being created for resistance input,
digital input, and current input with hart
* use voltage input channels spec for high impedance mode
* put () around macro parameters
* merge AD74413R_CHANNEL macro into its uses
* remove unused switch case scope
* inline return IIO_VAL_INT
* use {get,put}_unaligned_be16
* use proper types for reg and val
* move default case handling into switch statements
* pass driver state into regmap functions
* use genmask for generating a 16bit max value
* alphanumeric order for part numbers
* dt-bindings: remove $ref from ohms value
V4 -> V5
* dt-bindings: include headers necessary
* dt-bindings: add IRQ_TYPE_EDGE_FALLING to interrupt flags
* dt-bindings: ohm -> ohms
* dt-bindings: spi0 -> spi
V5 -> V6
* fix warnings regarding overflows
V6 -> V7
* remove extra cache-line alignment
* adi,rsense-resistance-ohms -> shunt-resistor-micro-ohms
* dt-bindings: add product page links
V7 -> V8
* also check DAC code lower bound
* fix checkpath --strict complaints
* add comment regarding mutex lock usage
* propagate error when converting adc result to resistance
V8 -> V9
* fix spelling mistake
* undo propagate error when converting adc result to resistance
* return void from adc result to resistance function
* limit max adc value when doing resistance calculation to avoid
a potential division-by-zero case
V9 -> V10
* pick up Reviewed-By tags
* fix odd alignment in header
* add dev_err_probe to irq request error path
