+Generic reboot mode communication driver
+
+This driver get reboot mode arguments from userspace
+and stores it in special register or ram . Then the
+bootloader will read it and take different action
+according the argument stored.
+
+Required properties:
+ - compatible = "reboot-mode" or other vendor compatible string;
+
+Each mode is represented as a sub-node of reboot_mode:
+
+Subnode required properties:
+ - linux,mode: reboot mode command,such as "loader","recovery", "fastboot".
+ - linux,magic: magic number for the mode, this is vendor specific.
+
+example:
+ reboot_mode {
+ compatible = "rockchip,reboot-mode";
+ rockchip,regmap = <&pmu>;
+ offset = <0x40>;
+ loader {
+ linux,mode = "loader";
+ linux,magic = <0x5242C301>;
+ };
+
+ maskrom {
+ linux,mode = "maskrom";
+ linux,magic = <0x5242C302>;
+ };
+
+ recovery {
+ linux,mode = "recovery";
+ linux,magic = <0x5242C303>;
+ };
+
+ fastboot {
+ linux,mode = "fastboot";
+ linux,magic = <0x5242C309>;
+ };
+ };
