Subject: [PATCH v1 0/4] Support MTK reboot mode driver
Date: Tue, 26 Nov 2019 13:34:46 +0800 [thread overview]
Message-ID: <1574746490-625-1-git-send-email-freddy.hsin@mediatek.com> (raw)
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
