Every clock is divided into 32 taps equally and the max value is 31. Fix rockchip,txclk-tapnum property in snps,dwcmshc-sdhci.yaml by adding a minimum, maximum and default. In the driver the function of_property_read_u8() is used, but with dtbs_check the notifications only disappear in YAML by changing uint8 to uint32. The driver has no limit check for rockchip,txclk-tapnum. make ARCH=arm64 dtbs_check Signed-off-by: Johan Jonker --- Documentation/devicetree/bindings/mmc/snps,dwcmshc-sdhci.yaml | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/Documentation/devicetree/bindings/mmc/snps,dwcmshc-sdhci.yaml b/Documentation/devicetree/bindings/mmc/snps,dwcmshc-sdhci.yaml index e6c9a2f77..f43d8d829 100644 --- a/Documentation/devicetree/bindings/mmc/snps,dwcmshc-sdhci.yaml +++ b/Documentation/devicetree/bindings/mmc/snps,dwcmshc-sdhci.yaml @@ -48,7 +48,10 @@ properties: rockchip,txclk-tapnum: description: Specify the number of delay for tx sampling. - $ref: /schemas/types.yaml#/definitions/uint8 + $ref: /schemas/types.yaml#/definitions/uint32 + minimum: 0 + maximum: 31 + default: 8 required:
