Subject: Re: [PATCH] clk: mediatek: mt8183: Correct parent of CLK_INFRA_SSPM_32K_SELF

Quoting Chen-Yu Tsai (2024-02-19 02:51:24)
> CLK_INFRA_SSPM_32K_SELF has the "f_f26m_ck" clock assigned as its parent.
> This is inconsistent as the clock is part of a group that are all gates
> without dividers, and this makes the kernel think it runs at 26 MHz.

> After clarification from MediaTek engineers, the correct parent is
> actually the system 32 KHz clock.
