From: Hugo Villeneuve <hvilleneuve@xxxxxxxxxxxx> Hello, this patch series adds the driver for the Texas Instruments ADS7924. 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.
