Change since v3: dt-bindings: - Fix properties:aspeed,int_vref_mv type error. Change since v2: dt-bindings: - Create a new dt-bindings for ast2600 adc aspeed_adc.c: - Splits the patch for more details - Remove version enum and use the flags in model data to distinguish hardware feature - Support trimming data get and set. - Use devm_add_action_or_reset to simplify probe error handling. Changes since v1: dt-bindings: - Fix the aspeed,adc.yaml check error. - Add battery-sensing property. aspeed_adc.c: - Change the init flow: Clock and reference voltage setting should be completed before adc engine enable. - Change the default sampling rate to meet most user case. - Add patch #8 to suppoert battery sensing mode. Billy Tsai (15): dt-bindings: iio: adc: Add ast2600-adc bindings iio: adc: aspeed: completes the bitfield declare. iio: adc: aspeed: set driver data when adc probe. iio: adc: aspeed: Keep model data to driver data. iio: adc: aspeed: Refactory model data structure iio: adc: aspeed: Add vref config function iio: adc: aspeed: Set num_channels with model data iio: adc: aspeed: Use model_data to set clk scaler. iio: adc: aspeed: Use devm_add_action_or_reset. iio: adc: aspeed: Support ast2600 adc. iio: adc: aspeed: Fix the calculate error of clock. iio: adc: aspeed: Add func to set sampling rate. iio: adc: aspeed: Add compensation phase. iio: adc: aspeed: Support battery sensing. iio: adc: aspeed: Get and set trimming data. .../bindings/iio/adc/aspeed,ast2600-adc.yaml | 97 +++ drivers/iio/adc/aspeed_adc.c | 562 +++++++++++++++--- 2 files changed, 569 insertions(+), 90 deletions(-) create mode 100644 Documentation/devicetree/bindings/iio/adc/aspeed,ast2600-adc.yaml
