[PATCH 0/2] dt-bindings: usb: generic-ehci/ohci: Document power-domains property

[Geert Uytterhoeven]

	Hi Greg, Rob,

It is quite common for a generic EHCI or OHCI block to be embedded in an
SoC in its own power domain.  However, the current DT bindings do not
cover this yet, leading to "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]+'
    arch/arm64/boot/dts/renesas/r8a774a1-hihope-rzg2m.dt.yaml: usb@ee080100: 'power-domains' does not match any of the regexes: 'pinctrl-[0-9]+'

This patch series documents the optional presence of "power-domains"
properties in the EHCI and OHCI devices nodes, allowing the DTS writer
to describe the controllers' positions in the power hierarchy.

Thanks!

[PATCH 1/2] dt-bindings: usb: generic-ehci: Document power-domains property

[Geert Uytterhoeven]

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]+'
