From cd597ce6460dc01f30f0f4158bbf20624c33c594 Mon Sep 17 00:00:00 2001 From: Tommaso Merciai Date: Mon, 22 Dec 2025 14:43:42 +0100 Subject: [PATCH] dt-bindings: phy: renesas,usb2-phy: Document mux-states property Some Renesas SoCs, such as RZ/G3E, provide a USB2.0 OTG PHY with configurable VBUS control through a multiplexed hardware register. This register allows selecting the VBUS source via a mux control line exposed by the PHY. To represent this hardware configuration, support the standard `mux-states` property in the Renesas USB2 PHY binding. This allows the DeviceTree to model the VBUS source selection as a mux, consistent with generic binding conventions.
