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

From: Freddy Hsin (èæè)
Date: Tue Nov 26 2019 - 00:41:11 EST


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
