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
Optional Properties:
-qcom,force-warm-reboot: Issue a warm reboot, even for the traditional cases
where hard reboot is issued.
-qcom,force-warm-reboot-on-thermal-shutdown: Issue a warm reboot on
"shutdown,thermal" restart reason.
Example:
restart@fc4ab000 {
compatible = "qcom,pshold";
reg = <0xfc4ab000 0x4>;
};
