From: David Lechner <dlechner@xxxxxxxxxxxx> Adding AD7383 and AD7384 compatible parts that are pseudo-differential. Pseudo-differential require common mode voltage supplies, so add them conditionally Signed-off-by: David Lechner <dlechner@xxxxxxxxxxxx> Signed-off-by: Julien Stephan <jstephan@xxxxxxxxxxxx> --- .../devicetree/bindings/iio/adc/adi,ad7380.yaml | 32 ++++++++++++++++++++++ 1 file changed, 32 insertions(+) diff --git a/Documentation/devicetree/bindings/iio/adc/adi,ad7380.yaml b/Documentation/devicetree/bindings/iio/adc/adi,ad7380.yaml index 5e1ee0ebe0a2..de3d28a021ae 100644 --- a/Documentation/devicetree/bindings/iio/adc/adi,ad7380.yaml +++ b/Documentation/devicetree/bindings/iio/adc/adi,ad7380.yaml @@ -13,6 +13,8 @@ maintainers: description: | * https://www.analog.com/en/products/ad7380.html * https://www.analog.com/en/products/ad7381.html + * https://www.analog.com/en/products/ad7383.html + * https://www.analog.com/en/products/ad7384.html $ref: /schemas/spi/spi-peripheral-props.yaml# @@ -21,6 +23,8 @@ properties: enum: - adi,ad7380 - adi,ad7381 + - adi,ad7383 + - adi,ad7384 reg: maxItems: 1 @@ -42,6 +46,16 @@ properties: A 2.5V to 3.3V supply for the external reference voltage.
