The issue is we only look at the first compatible. I'm testing out a fix and will apply it tomorrow assuming no issues. With that, I don't think we should apply this patch. > > Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> > > --- > > Cc: Akhil P Oommen <quic_akhilpo@quicinc.com> > --- > .../devicetree/bindings/display/msm/gmu.yaml | 12 ++++++++++++ > 1 file changed, 12 insertions(+) > > diff --git a/Documentation/devicetree/bindings/display/msm/gmu.yaml b/Documentation/devicetree/bindings/display/msm/gmu.yaml > index b3837368a260..8d1b515f59ec 100644 > --- a/Documentation/devicetree/bindings/display/msm/gmu.yaml > +++ b/Documentation/devicetree/bindings/display/msm/gmu.yaml > @@ -17,6 +17,18 @@ description: | > management and support to improve power efficiency and reduce the load on > the CPU. > > +# dtschema does not select nodes based on pattern+const, so add custom select > +# as a work-around: > +select: > + properties: > + compatible: > + contains: > + enum: > + - qcom,adreno-gmu > + - qcom,adreno-gmu-wrapper > + required: > + - compatible > + > properties: > compatible: > oneOf: > -- > 2.43.0 >

This is gmu, so can be just ignored/skipped. Anyway the code here should not have negative effect, so we can revert it anytime later, e.g. when users upgrade to fixed dtschema.

dtschema v2024.4, v2024.5 and maybe earlier do not select device nodes for given binding validation if the schema contains compatible list with pattern and a const fallback. This leads to binding being a no-op - not being applied at all. Issue should be fixed in the dtschema but for now add a work-around do the binding can be used against DTS validation.
