Subject: [PATCH v1 0/4] resubmit: add MTK reboot mode driver

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
    Gernation Unit) reboot driver
