Subject: [PATCH RESEND v2] arm64: dts: mt8195-cherry-tomato: change watchdog reset boot flow
Date: Fri, 18 Aug 2023 04:51:17 +0000 [thread overview]
Message-ID: <20230818-send-upstream-v2-1-f10d951a2971@google.com> (raw)
From: Hsin-Te Yuan <yuanhsinte@chromium.org>
The external output reset signal was originally disabled and sent from
firmware. However, an unfixed bug in the firmware on tomato prevents
the signal from being sent, causing the device to fail to boot. To fix
this, enable external output reset signal to allow the device to reboot
normally.
Signed-off-by: Hsin-Te Yuan <yuanhsinte@google.com>

Changes in v2:
- Limit the effect only on tomato.
