Subject: [PATCH v2 3/6] dt-bindings: phy: realtek,usb2phy.yaml: extend for resets and RTL9607C support
Date: Fri, 27 Mar 2026 21:06:35 +0500 [thread overview]
Message-ID: <20260327160638.15134-4-adilov@disroot.org> (raw)
In-Reply-To: <20260327160638.15134-1-adilov@disroot.org>
Add the "realtek,rtl9607-usb2phy" compatible for USB2 PHY on the RTL9607C
SoC series.
Add a resets property to properties to describe the usb2phy reset line.
In RTL9607C, USB2 PHY reset line is from "IP Enable controller" which is
multipurpose and handle activating various SoC peripherals.
It is unclear whether RTD SoCs have something similar to that so set
the resets to false for these devices.
RTL9607C requires the "resets" to be specified so add the corresponding
if check for the "realtek,rtl9607-usb2phy" compatible.
