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 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.
