From f98d7c3abca05471706c32ac47ec42fb4c71264d Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 26 Mar 2020 17:38:05 +0100 Subject: [PATCH] dt-bindings: usb: generic-ehci: Document power-domains property 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 Reviewed-by: Yoshihiro Shimoda Signed-off-by: Rob Herring --- Documentation/devicetree/bindings/usb/generic-ehci.yaml | 3 +++ 1 file changed, 3 insertions(+) diff --git a/Documentation/devicetree/bindings/usb/generic-ehci.yaml b/Documentation/devicetree/bindings/usb/generic-ehci.yaml index 10edd05872ea..848eea59bc00 100644 --- a/Documentation/devicetree/bindings/usb/generic-ehci.yaml +++ b/Documentation/devicetree/bindings/usb/generic-ehci.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: -- 2.39.5
