AD7877 TOUCHSCREEN DRIVER

S: Supported
This adds a binding specification for the Analog Devices Inc. AD7380 family of ADCs. Signed-off-by: David Lechner <dlechner@baylibre.com> --- As discussed in [1], the proposed spi-rx-bus-channels property is a complex new SPI core feature, so it was nacked for now on the grounds that it should be accepted without the corresponding SPI core changes. I dropped the Reviewed-by since no DT maintainers responded on that thread. [1]: https://lore.kernel.org/linux-spi/0a774bc6-3bf9-4b5f-92e0-8bd673e71a33@sirena.org.uk/ Changes in v4: - Dropped spi-rx-bus-channels property. Changes in v3: - Picked up Conor's Reviewed-By on the adi,ad7380 bindings Changes in v2: - Added new patch with generic spi-rx-bus-channels property - Added maxItems to reg property - Replaced adi,sdo-mode property with spi-rx-bus-channels - Made spi-rx-bus-channels property optional with default value of 1 (this made the if: check more complex) - Changed example to use gpio for interrupt .../devicetree/bindings/iio/adc/adi,ad7380.yaml | 86 ++++++++++++++++++++++ MAINTAINERS | 9 +++ 2 files changed, 95 insertions(+)
