Add Maxim max34408/34409 ADC driver and yaml for it. Until now it supports only current monitioring function without overcurrent threshold/delay, shutdown delay configuration, alert interrupt. Changes from v1: - minor changes from Rob's comments for yaml - add ena, shtdn and make 4 inputs for R sense from Jonathan's comments for yaml - add _REG suffix and make prefix for bitmasks and statuses - add SCALE/OFFSET instead of AVG/PROCESSED from Jonathan and Lars-Peter comments - add chip data from Jonathan and Lars-Peter comments - minor changes from Lars-Peter and Jonathan comments for driver Changes from v2: - add channels into hardware description into yaml - add rsense property per channel - rename pins for shtdn and ena pins - make one array for input_rsense values Changes from v3: - change *_34408_OCT3 and 4 to *_34409_OCT3 and 4 - change of_property_read_u32 to fwnode family calls - add i2c dev table - change of_match_device to i2c_of_match_device - change match->data to i2c_get_match_data Changes from v4: - minor changes in yaml Ivan Mikhaylov (2): dt-bindings: adc: provide max34408/9 device tree binding document iio: adc: Add driver support for MAX34408/9 .../bindings/iio/adc/maxim,max34408.yaml | 141 +++++++++ drivers/iio/adc/Kconfig | 11 + drivers/iio/adc/Makefile | 1 + drivers/iio/adc/max34408.c | 278 ++++++++++++++++++ 4 files changed, 431 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/adc/maxim,max34408.yaml create mode 100644 drivers/iio/adc/max34408.c -- 2.42.0
