It is quite common for a generic EHCI block to be embedded in an SoC in its own power domain. 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@ee080100: 'power-domains' does not match any of the regexes: 'pinctrl-[0-9]+' Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- Documentation/devicetree/bindings/usb/generic-ehci.yaml | 3 +++ 1 file changed, 3 insertions(+)
