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!
