The Texas Instruments ADS7924 is a 4 channels, 12-bit analog to digital converter (ADC) with an I2C interface. Patch 1 adds a Kconfig comment to help differentiate between the Analog Devices AD7924 (SPI) and the TI ADS7924 (I2C). Patch 2 contains the driver for the ADS7924. Patch 3 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.
