The generic IIO channel bindings is also introduced here to provide this feature. The legacy channel binding is kept for backward compatibility. Changes in v2: - Add 'deprecated' to channels legacy properties in ADC bindings - Add set/clr service for common registers, to make code more generic in internal channels enable/disable services. - Expose vrefint channel as a processed channel to return the actual value of vrefp. - Minor code improvements Olivier Moysan (7): dt-bindings: iio: stm32-adc: add generic channel binding dt-bindings: iio: stm32-adc: add nvmem support for vrefint internal channel iio: adc: stm32-adc: split channel init into several routines iio: adc: stm32-adc: add support of generic channels binding iio: adc: stm32-adc: add support of internal channels iio: adc: stm32-adc: add vrefint calibration support iio: adc: stm32-adc: use generic binding for sample-time .../bindings/iio/adc/st,stm32-adc.yaml | 108 ++++- drivers/iio/adc/stm32-adc-core.h | 8 + drivers/iio/adc/stm32-adc.c | 424 ++++++++++++++++-- 3 files changed, 485 insertions(+), 55 deletions(-)
