[PATCH v8 1/6] dt-bindings: phy: samsung,usb3-drd-phy: add ExynosAutov920 HS phy compatible
From: Pritam Manohar Sutar <hidden>
Date: 2025-09-03 07:29:40
Also in:

Subsystem:
generic phy framework, open firmware and flattened device tree bindings, the rest · Maintainers:
Vinod Koul, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
Document support for the USB20 phy found on the ExynosAutov920 SoC. The USB20 phy is functionally identical to that on the Exynos850 SoC, so no driver changes are needed to support this phy. However, add a dedicated compatible string for USB20 phy found in this SoC.
