Subject: [PATCH 0/2] Add a watchdog driver that uses ARM Secure Monitor Calls.
Date: Fri, 14 Feb 2020 17:26:35 +1100 [thread overview]
Message-ID: <20200214062637.216209-1-evanbenn@chromium.org> (raw)
This is currently supported in firmware deployed on oak, hana and elm mt8173
chromebook devices. The kernel driver is written to be a generic SMC
watchdog driver.
Arm Trusted Firmware upstreaming review:
https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/3405
Patch to add oak, hana, elm device tree:
https://lore.kernel.org/linux-arm-kernel/20200110073730.213789-1-hsinyi@chromium.org/
I would like to add the device tree support after the above patch is
accepted.
