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>;

	};
