Subject: Re: [PATCH RESEND v3 3/5] clk: mediatek: Pass device to clk_hw_register for PLLs

Quoting Nicolas Frattaroli (2025-12-15 03:24:00)
> Passing the struct device pointer to clk_hw_register allows for runtime
> power management to work for the registered clock controllers. However,
> the mediatek PLL clocks do not do this.
> 
> Change this by adding a struct device pointer argument to
> mtk_clk_register_pll, and fix up the only other user of it. Also add a
> new member to the struct mtk_clk_pll for the struct device pointer,
> which is set by mtk_clk_register_pll and is used by
> mtk_clk_register_pll_ops.
> 
> If mtk_clk_register_pll is called with a NULL struct device pointer,
> then everything still works as expected; the clock core will simply
> treat them as previously, i.e. without runtime power management.
