Hello, sending out v4 splitting device tree bindings documentation and actual ADC driver. No changes in driver code since v3.
Same question for iio maintainers here: I would like to have clarified the measure unit returned by read_raw(). Currently (value_raw * value_scale) return the ADC input value in mV. While testing the patch I've been questioned if that should not actually be in uV. This is easily achievable making _scale return a value in uV. I have found no mention of this in the ABI documentation as it speaks of generic voltage. Can we have a final word on this? Thanks Marek for having tested this. v1 -> v2: - incorporated pmeerw's review comments - retrieve vref from dts and use that to convert read_raw result to mV - add device tree bindings documentation v2 -> v3: - add _SCALE bit of read_raw function and change _RAW bit accordingly - call regulator_get_voltage when accessing the _SCALE part of read_raw and not during probe - add back remove function as regulator has to be disabled when detaching the module. Do not use devm_ version of iio_register/unregister functions anymore but do unregister in the remove. - remove mutex as access to SPI bus is protected by SPI core. Thanks marex v3 -> v4: - split device tree binding documentation and actual ADC driver - add "reg" to the list of required properties and use a better namimg for the adc device node in bindings documentation as suggested by Geert.
