Hi, Coner and Krzysztof,

Next version I will change commit message:

dt-bindings: power: Add JH7110 DPHY PMU support.

Add DPHY PMU for StarFive JH7110 SoC, it can be used to turn on/off DPHY rx/tx
power switch, and it don't need the reg and interrupt properties.

I think this commit message will helpful for you to understand it.

Best regards,
Changhuang
