Or a pre-requisite for thermal and auxadc drivers? I don't understand the priority of this patch. Should I apply it to fix a regression?

I'd say 'no', as AUXADC and thermal has not yet been added to mt7986a.dtsi, also the corresponding clocks are currently still unused. So while this commit does fix a previous commit, it doesn't have a direct impact and will only matter once thermal and auxadc units are added to mt7986.dtsi.

Thanks! Please include these details next time.

It seems like CLK_INFRA_ADC_FRC_CK always need to be enabled for CLK_INFRA_ADC_26M_CK to work. Instead of adding this dependency to the mtk-thermal and mt6577_auxadc drivers, add dependency to the clock driver clk-mt7986-infracfg.c.
