This driver parses the reboot commands like "reboot bootloader"
 and "reboot recovery" to get a boot mode described in the
 device tree , then call the write interfae to store the boot
 mode in mtk RGU (reset generation unit) non-volatile register,
 which can be read by the bootloader after system reboot, then
 the bootloader can take different action according to the mode
 stored.
 
 Freddy Hsin (4):
  power: reset: add reboot mode driver
  watchdog: populate reboot mode node in toprgu node of MTK RGU (Reset
    Generation Unit)
  soc: mediatek: add reboot-mode header
  dt-binding: power: reset: Add documentation for MTK RGU (Reset
