-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>;
- };
