While these abbreviations are fairly common when talking about SPI, and thus may not need an explanation, they are not entirely correct in this context, as the SPI controller may be used in slave mode instead of master mode. Fix this by replacing them by "read transfers" resp. "write transfers", like is done for the spi-rx-delay-us and spi-tx-delay-us properties.

This issue was present in the .txt version of the bindings, too, so technically it needs Fixes: a8830cb19cfea04e ("spi: Document DT bindings for SPI controllers in slave mode") but of course it won't apply to that version. --- Documentation/devicetree/bindings/spi/spi-controller.yaml | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/Documentation/devicetree/bindings/spi/spi-controller.yaml b/Documentation/devicetree/bindings/spi/spi-controller.yaml index 0ebaf6677ac4f68d..d8e5509a70816df5 100644 --- a/Documentation/devicetree/bindings/spi/spi-controller.yaml +++ b/Documentation/devicetree/bindings/spi/spi-controller.yaml @@ -120,7 +120,7 @@ patternProperties: - enum: [ 1, 2, 4, 8 ] - default: 1 description: - Bus width to the SPI bus used for MISO. + Bus width to the SPI bus used for read transfers. spi-rx-delay-us: description: @@ -132,7 +132,7 @@ patternProperties: - enum: [ 1, 2, 4, 8 ] - default: 1 description: - Bus width to the SPI bus used for MOSI. + Bus width to the SPI bus used for write transfers. spi-tx-delay-us: description:
