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>;
|
|
};
