Subject: [PATCH 0/4] Add restart commands for PM8150
Date: Fri, 31 Jul 2020 14:14:16 -0700 [thread overview]
Message-ID: <1596230060-6065-1-git-send-email-eberman@codeaurora.org> (raw)
PM8150 uses reboot-mode framework to set magic values for bootloader to read
during next boot. dm-verity wants to use "dm-verity device corrupted" [1] as
the restart command, however the reboot-mode framework does not support spaces
in the command line as devicetree property names cannot have spaces. This
patch series adds two new optional array properties to reboot-mode framework:
reboot-mode-names and reboot-mode-magic. The arrays supply the commands and
magic values, respectively.
