[PATCH v3 0/2] iio: adc: Add Intel Dollar Cove TI PMIC ADC driver

[Hans de Goede <hansg@kernel.org>]

Hi,

Here is v3 of my patch to add an IIO driver for the Intel Dollar Cove TI
PMIC ADC.

Changes in v3:
- "iio: Improve iio_read_channel_processed_scale() precision"
  - Use div_s64() instead of div_u64() to fix -1.0 - 0.0 range
  - Directly return IIO_VAL_INT from valid cases and drop the final
    return ret after the switch-case
- "iio: adc: Add Intel Dollar Cove TI PMIC ADC driver"
  - Use new more compact DC_TI_ADC_DATA_REG_CH(x) macro
  - Use regmap_set_bits() regmap_clear_bits() where applicable
  - Use regmap_bulk_read() + be16_to_cpu() to read ADC value
  - Use sign_extend32() for vbat_zse and vbat_ge reading in probe()

Changes in v2:
- Add new "iio: Improve iio_read_channel_processed_scale() precision"
  patch to the series
- Add IIO_CHAN_INFO_SCALE and provide ADC scale info for Vbat
- Add IIO_CHAN_INFO_PROCESSED which applies calibration and
  scaling for the VBat channel
- Address some other small review remarks

Regards,

Hans
