Hence allow the DTS writer to describe the controller's position in the power hierarchy, by documenting the optional presence of a "power-domains" property. This gets rid of "make dtbs_check" warnings like: arch/arm64/boot/dts/renesas/r8a774a1-hihope-rzg2m.dt.yaml: usb@ee080000: 'power-domains' does not match any of the regexes: 'pinctrl-[0-9]+' Signed-off-by: Geert Uytterhoeven --- Documentation/devicetree/bindings/usb/generic-ohci.yaml | 3 +++ 1 file changed, 3 insertions(+) diff --git a/Documentation/devicetree/bindings/usb/generic-ohci.yaml b/Documentation/devicetree/bindings/usb/generic-ohci.yaml index bcffec1f1341e502..d7efddf27b22e264 100644 --- a/Documentation/devicetree/bindings/usb/generic-ohci.yaml +++ b/Documentation/devicetree/bindings/usb/generic-ohci.yaml @@ -36,6 +36,9 @@ properties: - if a USB DRD channel: first clock should be host and second one should be peripheral + power-domains: + maxItems: 1 + big-endian: $ref: /schemas/types.yaml#/definitions/flag description:
