Subject: [PATCH 0/2] watchdog: imx_wdt2: Enable ping on suspend support
Date: Sun, 9 Jan 2022 21:41:18 +1000 [thread overview]
Message-ID: <20220109114120.386013-1-alistair@alistair23.me> (raw)
When running Linux on the reMarkable2 tablet the device reboots two
minutes after suspend. This is because we don't go into low power
mode so the watchdog timer is still running and triggers a reboot.
This series adds optional support for ping on suspend for the
i.MX watchdog timer and then enables it for the reMarkable2 tablet.
