Removing them from the example > is the easiest solution to silence the warnings. It's not clear to me, what has to be done to see this warning. Can you tell me how to reproduce? My current WIP patch is: diff --git a/Documentation/devicetree/bindings/mtd/mxc-nand.yaml b/Documentation/devicetree/bindings/mtd/mxc-nand.yaml index 73b86f2226c7..6e3e346e4448 100644 --- a/Documentation/devicetree/bindings/mtd/mxc-nand.yaml +++ b/Documentation/devicetree/bindings/mtd/mxc-nand.yaml @@ -14,7 +14,18 @@ allOf: properties: compatible: - const: fsl,imx27-nand + oneOf: + - const: fsl,imx21-nand + - const: fsl,imx25-nand + - const: fsl,imx27-nand + - items: + - const: fsl,imx31-nand + - const: fsl,imx27-nand + - items: + - const: fsl,imx35-nand + - const: fsl,imx27-nand + - const: fsl,imx51-nand + - const: fsl,imx53-nand reg: maxItems: 1 which I think is right, but obviously doesn't fix the problem you pointed out :-) > Signed-off-by: Rob Herring <robh@kernel.org> > --- > These properties may be deprecated, but they are still widely used in > bindings.

Nope, read my note below. 'nand-bus-width' is documented as a nand chip (child node) property, not a nand controller property. > regards, > Marc > > > --- > > These properties may be deprecated, but they are still widely used in > > bindings.

With unevaluatedProperties issues fixed, 'nand-bus-width' and 'nand-ecc-mode' are flagged as undocumented. Removing them from the example is the easiest solution to silence the warnings. Signed-off-by: Rob Herring <robh@kernel.org> --- These properties may be deprecated, but they are still widely used in bindings. They either need to be documented (and marked deprecated) or removed from current users (i.e. dts files). --- Documentation/devicetree/bindings/mtd/mxc-nand.yaml | 2 -- 1 file changed, 2 deletions(-)
