The implemented driver provides basic functionality for getting ADC channels data. Change History: v2: - Added lastch flag to avoid addition work for already selected channel - Added reset assertion on module remove - Added dynamic channel allocation and dropped iio_chan_spec arrays - Changed IIO_CHAN_INFO_SCALE type to FRACTIONAL_LOG2 - Dropped separate compatible strings and configs for T113s and R329 - Fixed includes - Fixed Kconfig description - Removed duplicate probe error messages - Used FIELD_PREP for bit setup v1: - Initial version Maxim Kiselev (3): iio: adc: Add Allwinner D1/T113s/R329/T507 SoCs GPADC dt-bindings: iio: adc: Add Allwinner D1/T113s/R329/T507 SoCs GPADC riscv: dts: allwinner: d1: Add GPADC node .../iio/adc/allwinner,sun20i-d1-gpadc.yaml | 79 +++++ .../boot/dts/allwinner/sunxi-d1s-t113.dtsi | 10 + drivers/iio/adc/Kconfig | 10 + drivers/iio/adc/Makefile | 1 + drivers/iio/adc/sun20i-gpadc-iio.c | 296 ++++++++++++++++++ 5 files changed, 396 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/adc/allwinner,sun20i-d1-gpadc.yaml create mode 100644 drivers/iio/adc/sun20i-gpadc-iio.c
