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>;
|
|
};
