The Texas Instruments ADS7924 is a 4 channels, 12-bit analog to digital converter (ADC) with an I2C interface. Patch 1 contains the driver for the ADS7924. Patch 2 add the dt-bindings for the ADS7924. I have tested the driver using the Texas Instruments ADS7924EVM board connected to a Variscite Symphony EVK with a IMX8MN NANO SOM: - Tested reset pin Ok - Tested regulator setup Ok - Tested reading sysfs in_voltage_scale Ok - Tested reading sysfs in_voltageX_raw (x=0 to 3) Ok Thank you. Link: [v1] https://lore.kernel.org/linux-iio/20221222203610.2571287-1-hugo@hugovil.com/#t Changes for V2: - Dropped patch "iio: adc: Kconfig: add SPI interface mention to AD7924 description" - Fixed comments style - Removed unused defines/variables/etc related to buffered support (no buffered support for the moment). - Convert of-specific code to use the generic firmware property accessors in include/linux/property.h. - Use FIELD_GET / FIELD_PREP for bit operations/defines - Simplified conversion result registers definitions/usage. - Now using mutex lock/unlock only for INFO_RAW switch branch - Use dev_err_probe() in all return paths of ads7924_probe() - Removed ads7924_remove() after adding callbacks with devm_add_action_or_reset(). - Change iio_device_register() to devm_iio_device_register(). - Add the legacy i2c_device_id table - DT bindings: reorder entries, fix indentation,improve comments, add interrupt line Hugo Villeneuve (2): iio: adc: ti-ads7924: add Texas Instruments ADS7924 driver dt-bindings: iio: adc: add Texas Instruments ADS7924 .../bindings/iio/adc/ti,ads7924.yaml | 104 ++++ MAINTAINERS | 7 + drivers/iio/adc/Kconfig | 11 + drivers/iio/adc/Makefile | 1 + drivers/iio/adc/ti-ads7924.c | 492 ++++++++++++++++++ 5 files changed, 615 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/adc/ti,ads7924.yaml create mode 100644 drivers/iio/adc/ti-ads7924.c base-commit: bfcae956d9b50ea0e221cefc171604c569017d7e
