-A power supply hold (ps-hold) bit is set to power the msm chipsets.
-Clearing that bit allows us to restart/poweroff. The difference
-between poweroff and restart is determined by unique power manager IC
-settings.
-
-Required Properties:
--compatible: "qcom,pshold"
--reg: Specifies the physical address of the ps-hold register
-
-Example:
-
-	restart@...ab000 {
-		compatible = "qcom,pshold";
-		reg = <0xfc4ab000 0x4>;
