Hi Elon, Thanks for the patch. Overall, this patch needs a bit of cleanup. There are many nodes added which are not available in mainline.
Please see comments inline.

I can see some old patches in lkml archive but not sure about the status of those. So, please remove this node and use dummy regulators where applicable. > + reg = <0x20>; > + interrupt-parent = <&gpio1>; > + interrupts = <RK_PC2 IRQ_TYPE_LEVEL_LOW>; > + pinctrl-names = "default", "pmic-sleep", > + "pmic-power-off", "pmic-reset";
