MSM Restart Driver
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@fc4ab000 {
compatible = "qcom,pshold";
reg = <0xfc4ab000 0x4>;
};
