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. --- David Lechner (2): dt-bindings: iio: adc: add ad7944 ADCs iio: adc: ad7944: add driver for AD7944/AD7985/AD7986 .../devicetree/bindings/iio/adc/adi,ad7944.yaml | 231 ++++++++++++ MAINTAINERS | 9 + drivers/iio/adc/Kconfig | 10 + drivers/iio/adc/Makefile | 1 + drivers/iio/adc/ad7944.c | 397 +++++++++++++++++++++ 5 files changed, 648 insertions(+) --- base-commit: 81e8e40ea16329914f78ca1f454d04f570540ca8 change-id: 20240206-ad7944-mainline-17c968aa0967
