Subsystem:
generic phy framework, open firmware and flattened device tree bindings, starfive jh7110 dphy rx driver, the rest · Maintainers:
Vinod Koul, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Jack Zhu, Changhuang Liang, Linus Torvalds
Starfive SoCs like the jh7110 use a MIPI D-PHY RX controller based on a M31 IP. Add a binding for it.
