| 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: |
| -reg: A secondary reg address/size pair may be provided, to specify the address |
| of the TCSR_BOOT_MISC_DETECT register. This address is typically used to |
| configure the type of reset desired. Omitting this address implies that |
| the reset type shall be configured by means of a call to the secure |
| environment. |
| |
| Example: |
| |
| restart@fc4ab000 { |
| compatible = "qcom,pshold"; |
| reg = <0xfc4ab000 0x4>; |
| }; |
