[PATCH v2 2/8] dt-bindings: phy: snps-eusb2: add exynos2200 support

From: Ivaylo Ivanov <ivo.ivanov.ivanov1@gmail.com>
Date: 2025-02-23 12:22:36
Also in: linux-arm-msm, linux-devicetree, linux-phy, linux-samsung-soc, lkml
Subsystem: generic phy framework, open firmware and flattened device tree bindings, the rest · Maintainers: Vinod Koul, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

Exynos 2200 makes use of the Synposys eUSB2 IP, so document it in the
binding. Unlike the currently documented Qualcomm SoCs, it doesn't provide
reset lines for reset control and uses more clocks.
