No generic compatibles which even the author does not understand what it is. But if you re-use existing binding, then it is a proof that previous commit did something odd. > + > + reg: > + items: > + - description: The first region is the MAC core register base and size. > + - description: The second region is the global MAC control register. > + > + ranges: > + maxItems: 1 > + > + '#address-cells': > + const: 1 > + > + '#size-cells': > + const: 1 > + > + interrupts: > + maxItems: 1 > + > + clocks: > + maxItems: 3 > + > + clock-names: > + items: > + - const: mac > + - const: macif > + - const: phy > + > + resets: > + maxItems: 2 > + > + reset-names: > + items: > + - const: mac > + - const: phy > + > + hisilicon,phy-reset-delays-us: > + items: > + - description: The 1st cell is reset pre-delay in micro seconds. Drop redundant parts: "The 1st cell" and "micro seconds" and instead describe something useful. You have here nine words out of which 7 are redundant or not describing actual property and only two say something. What is "reset pre-delay"?
