+NVMEM reboot mode driver
+
+This driver gets reboot mode magic value from reboot-mode driver
+and stores it in a NVMEM cell named "reboot-mode". Then the bootloader
+can read it and take different action according to the magic
+value stored.
+
+Required properties:
+- compatible: should be "nvmem-reboot-mode".
+- nvmem-cells: A phandle to the reboot mode provided by a nvmem device.
+- nvmem-cell-names: Should be "reboot-mode".
+
+The rest of the properties should follow the generic reboot-mode description
+found in reboot-mode.txt
+
+Example:
+ reboot-mode {
+ compatible = "nvmem-reboot-mode";
+ nvmem-cells = <&reboot_mode>;
+ nvmem-cell-names = "reboot-mode";
+
+ mode-normal = <0xAAAA5501>;
+ mode-bootloader = <0xBBBB5500>;
+ mode-recovery = <0xCCCC5502>;
+ mode-test = <0xDDDD5503>;
+ };
