In additional, patch #6 is used to improve the adc accurate patch #7 is used to fix the clock issue in the original code. 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 (8): dt-bindings: iio: adc: rename the aspeed adc yaml dt-bindings: iio: adc: Binding ast2600 adc. iio: adc: aspeed: completes the bitfield declare. iio: adc: aspeed: Allow driver to support ast2600 iio: adc: aspeed: Add func to set sampling rate. iio: adc: aspeed: Add compensation phase. iio: adc: aspeed: Fix the calculate error of clock. iio: adc: aspeed: Support battery sensing. .../bindings/iio/adc/aspeed,adc.yaml | 79 ++++ .../bindings/iio/adc/aspeed,ast2400-adc.yaml | 55 --- drivers/iio/adc/aspeed_adc.c | 376 ++++++++++++++---- 3 files changed, 385 insertions(+), 125 deletions(-) create mode 100644 Documentation/devicetree/bindings/iio/adc/aspeed,adc.yaml delete mode 100644 Documentation/devicetree/bindings/iio/adc/aspeed,ast2400-adc.yaml
