This is a new driver for the Analog Devices AD7944/AD7985/AD7986 family
of ADCs. These are fairly simple chips (e.g. no configuration registers).
The initial driver is only supporting the 4-wire SPI mode. We plan to
follow up with support for the 3-wire SPI mode.
This work is done on behalf of Analog Devices, Inc., hence the
MAINTAINERS are @analog.com folks.
This has been tested using an EVAL-AD7985FMCZ evaluation board with a
Xilinx ZedBoard.
