The watchdog driver already registers a restart notifier, we just have to enable it in the config and in the DT to fix the "reboot" command. This is done by integratin the following patch-set: https://lkml.org/lkml/2015/2/20/610 I'm copy-pasting the description below: qcom-wdt is currently assuming the presence of a dedicated node in DT to gets its configuration. However, on msm architecture, the watchdog is usually part of the timer block. So this patch-set is changing the driver and slightly enhancing the timer DT bindings to provide the relevant clocks and interrupts.

Subject: [PATCH 3/3] ARM: msm: add watchdog entries to DT timer binding doc
|
|
|
|
The watchdog has been reworked to use the same DT node as the timer.
|
|
This change is updating the device tree doc accordingly.
