[Severity: High]
This isn't a bug introduced by this patch, but since you are fixing the
swapped supplies here, should this fix also be applied to other closely
related boards that appear to have the exact same misconfiguration?

For example, in arch/arm64/boot/dts/qcom/sc7280-idp.dtsi:

&usb_1_qmpphy {
	vdda-phy-supply = <&vreg_l6b_1p2>;
	vdda-pll-supply = <&vreg_l1b_0p8>;
}

And in arch/arm64/boot/dts/qcom/sc7280-qcard.dtsi:

&usb_1_qmpphy {
	vdda-phy-supply = <&vdd_a_usbssdp_0_1p2>;
	vdda-pll-supply = <&vdd_a_usbssdp_0_core>;
}

Similarly in arch/arm64/boot/dts/qcom/sc7180-ecs-liva-qc710.dts:

&usb_1_qmpphy {
	vdda-phy-supply = <&vreg_l3c_1p2>;
	vdda-pll-supply = <&vreg_l4a_0p8>;
}

>  
>  	orientation-switch;
