Geert Uytterhoeven a56cde4134 dt-bindings: mtd: jedec,spi-nor: Document CPOL/CPHA support ... SPI EEPROMs typically support both SPI Mode 0 (CPOL=CPHA=0) and Mode 3 (CPOL=CPHA=1). However, using the latter is currently flagged as an error by "make dtbs_check", e.g.: arch/arm/boot/dts/r8a7791-koelsch.dtb: flash@0: Unevaluated properties are not allowed ('spi-cpha', 'spi-cpol' were unexpected) From schema: Documentation/devicetree/bindings/mtd/jedec,spi-nor.yaml Fix this by documenting support for CPOL=CPHA=1. Fixes: 233363aba7 ("spi/panel: dt-bindings: drop CPHA and CPOL from common properties") Cc: stable@vger.kernel.org Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Reviewed-by: Miquel Raynal <miquel.raynal@bootlin.com> Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Reviewed-by: Tudor Ambarus <tudor.ambarus@linaro.org> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Link: https://lore.kernel.org/linux-mtd/afe470603028db9374930b0c57464b1f6d52bdd3.1676384304.git.geert+renesas@glider.be		2023-03-22 16:59:08 +01:00
