Re: [PATCH v3 1/3] dt-bindings: phy: rockchip: Add Naneng combo PHY bindings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Yifeng,

Driver and documents don't match.
Add a separate patch before this one to add to syscon.yaml:

"rockchip,rk3568-pipe-phy-grf", "syscon"
"rockchip,rk3568-pipe-grf", "syscon"

Remove.
DT node has 3 clocks and not 1.

Remove.
DT node has 2 resets and not 1.

There are 2 resets. When the reset order does matter then use
devm_reset_control_array_get() to get the resets.
The use of reset-names is then not needed.
