Add the "qcom,kaanapali-csi2-phy" compatible. Wrong, it is NOT compatible. Due to the functional difference in the register offset, which is described in the patch 0002, it is NOT possible to fallback to "qcom,x1e80100-csi2-phy" compatible device driver, and there shall be a new stand-alone compatible variable "qcom,kaanapali-csi2-phy". > Reviewed-by: Bryan O'Donoghue > Acked-by: Krzysztof Kozlowski > Signed-off-by: Hangxiang Ma > --- > Documentation/devicetree/bindings/phy/qcom,x1e80100-csi2-phy.yaml | 4 +++- > 1 file changed, 3 insertions(+), 1 deletion(-) > > diff --git a/Documentation/devicetree/bindings/phy/qcom,x1e80100-csi2-phy.yaml b/Documentation/devicetree/bindings/phy/qcom,x1e80100-csi2-phy.yaml > index 1f1e2a4993b2..6e9eb8e265df 100644 > --- a/Documentation/devicetree/bindings/phy/qcom,x1e80100-csi2-phy.yaml > +++ b/Documentation/devicetree/bindings/phy/qcom,x1e80100-csi2-phy.yaml > @@ -17,7 +17,9 @@ description: > properties: > compatible: > oneOf: > - - const: qcom,x1e80100-csi2-phy > + - enum: > + - qcom,kaanapali-csi2-phy > + - qcom,x1e80100-csi2-phy > - items: > - const: qcom,glymur-csi2-phy > - const: qcom,x1e80100-csi2-phy > -- Best wishes, Vladimir
