[PATCH 3/6] dt-bindings: iio: explicitly list SPI CPHA and CPOL
Krzysztof Kozlowski
krzysztof.kozlowski at linaro.org
Thu Jul 21 15:31:52 UTC 2022
The spi-cpha and spi-cpol properties are device specific and should be
accepted only if device really needs them. Explicitly list them in
device bindings in preparation of their removal from generic
spi-peripheral-props.yaml schema.
