Subject: Re: [PATCH v5 5/6] clk: wpcm450: Add Nuvoton WPCM450 clock/reset controller driver

Quoting Jonathan Neuschäfer (2022-11-04 09:18:49)
> This driver implements the following features w.r.t. the clock and reset
> controller in the WPCM450 SoC:
> 
> - It calculates the rates for all clocks managed by the clock controller
> - It leaves the clock tree mostly unchanged, except that it enables/
>   disables clock gates based on usage.
> - It exposes the reset lines managed by the controller using the
>   Generic Reset Controller subsystem
> 
> NOTE: If the driver and the corresponding devicetree node are present,
>       the driver will disable "unused" clocks. This is problem until
>       the clock relations are properly declared in the devicetree (in a
>       later patch). Until then, the clk_ignore_unused kernel parameter
>       can be used as a workaround.
