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!
