+Generic reboot mode core map driver
+
+This driver get reboot mode arguments and call the write
+interface to store the magic value in special register
+or ram. Then the bootloader can read it and take different
+action according to the argument stored.
+
+All mode properties are vendor specific, it is a indication to tell
+the bootloader what to do when the system reboots, and should be named
+as mode-xxx = <magic> (xxx is mode name, magic should be a none-zero value).
+
+For example modes common on Android platform:
+- mode-normal: Normal reboot mode, system reboot with command "reboot".
+- mode-recovery: Android Recovery mode, it is a mode to format the device or update a new image.
+- mode-bootloader: Android fastboot mode, it's a mode to re-flash partitions on the Android based device.
+- mode-loader: A bootloader mode, it's a mode used to download image on Rockchip platform,
+ usually used in development.
+
+Example:
+ reboot-mode {
+ mode-normal = <BOOT_NORMAL>;
+ mode-recovery = <BOOT_RECOVERY>;
+ mode-bootloader = <BOOT_FASTBOOT>;
+ mode-loader = <BOOT_BL_DOWNLOAD>;
+ }

+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>;
+ };
