- SYSCON reboot mode driver
- This driver gets reboot mode magic value form reboot-mode driver
- and stores it in a SYSCON mapped register. Then the bootloader
- can read it and take different action according to the magic
- value stored.
- This DT node should be represented as a sub-node of a "syscon", "simple-mfd"
- node.
- Required properties:
- - compatible: should be "syscon-reboot-mode"
- - offset: offset in the register map for the storage register (in bytes)
- Optional property:
- - mask: bits mask of the bits in the register to store the reboot mode magic value,
- default set to 0xffffffff if missing.
- The rest of the properties should follow the generic reboot-mode description
- found in reboot-mode.txt
- Example:
- pmu: pmu@20004000 {
- compatible = "rockchip,rk3066-pmu", "syscon", "simple-mfd";
- reg = <0x20004000 0x100>;
- reboot-mode {
- compatible = "syscon-reboot-mode";
- offset = <0x40>;
- mode-normal = <BOOT_NORMAL>;
- mode-recovery = <BOOT_RECOVERY>;
- mode-bootloader = <BOOT_FASTBOOT>;
- mode-loader = <BOOT_BL_DOWNLOAD>;
- };
- };
