Subject: Re: [PATCH v2 2/2] clk: mediatek: Remove CLK_SET_PARENT from all MSDC core clocks

Quoting AngeloGioacchino Del Regno (2023-05-16 06:52:05)
> Various MSDC core clocks, used for multiple MSDC controller instances,
> share the same parent(s): in order to add parents selection in the
> mtk-sd driver to achieve an accurate clock rate for all modes, remove
> the CLK_SET_RATE_PARENT flag from all MSDC clocks for all SoCs: this
> will make sure that a clk_set_rate() call performed for a clock on
> a secondary controller will not change the rate of a common parent,
> which would result in an overclock or underclock of one of the
> controllers.
