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

Commit Message

Ivaylo Ivanov Feb. 23, 2025, 12:22 p.m. UTC

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.
