1 GPIO Reboot Mode Configuration
4 - compatible: must be "reboot-mode-gpio".
5 - gpios: list of gpios that are used to calculate the reboot-mode magic value.
6 Every gpio represents a bit in the magic value in the same order
7 as defined in device tree.
8 - modes: list of properties that define the modes and associated unique ids.
11 - u-boot,env-variable: used to save the reboot mode (default: reboot-mode).
