AD7380, AD7381, AD7383, and AD7384 ADCs. These chips are part of a family of simultaneous sampling SAR ADCs. To keep things simple, the initial driver implementation only supports the 2-channel differential chips listed above. There are also 4-channel differential chips and 4-channel single-ended chips in the family that can be added later. Furthermore, the driver is just implementing basic support for capturing data. Additional features like interrupts, CRC, etc. can be added later. Also, FYI, this driver will also be used as the base for an upcoming series adding AXI SPI Engine offload support for these chips along with [1]. This work is being done by BayLibre and on behalf of Analog Devices Inc. hence the maintainers are @analog.com.
