Subject: [PATCH] arm64: dts: mt8173-oak: Switch to SMC watchdog
Date: Mon, 25 Jul 2022 16:24:47 +0800 [thread overview]
Message-ID: <20220725082447.2613231-1-treapking@chromium.org> (raw)
Switch to SMC watchdog because we need direct control of HW watchdog
registers from kernel. The corresponding firmware was uploaded in
https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/3405.
Signed-off-by: Pin-yen Lin <treapking@chromium.org>
