From: Andre Werner <andre.werner@xxxxxxxxxxxxxxxxxxxxx> Add basic description for ADS7x38 ADC devices. The driver does only support a very basic set of functionalities provided by the chip. Also, the example in the description covers only a setup for ADS7038 devices while the driver structure will support both ADS7038 (SPI) and ADS7138 (I2C) devices.
