Hi, > Wouldn't it be better to move it to the board file without having > intermediate include files? The intermediate include files were suggested by you: https://lore.kernel.org/lkml/xmvtbib3q72tnfpcaic3vbgwilpo7yjnqimr5uk2myjgtslbgm@mlp2kqvljayc/ Unlike mobile phones or development boards, the pmic (voltage) setting on routers is relatively fixed. (Because QCA will not provide relevant documents). On IPQ60xx SoCs, s2 supplies to cpu, l2 supplies to emmc. The downstream vendor kernel puts it in soc.dtsi (no device override), so I think the include files is more appropriate. Thanks, Chukun -- 2.25.1
