I'd like to use a watchdog on my MEDION P89626 but cannot find a device in /dev.
There is a reference to a watchdog device in ox820-stg212.dtb.
Can this be accessed by a watchdog service or should I compile a software watchdog into the kernel?

regards

I don't think we have hardware watchdog (or know how to turn it on if there were). So SW watchdog is what you want if needed.

Yes, I will go for the software watchdog.

Here is what I found out about the hardware watchdog for reference:

The device tree in ox820-stg212.dtb references a mpcore_wdt device:

        watchdog@47000620 {
                compatible = "mpcore_wdt";
                reg = <0x47000620 0x20>;
                interrupts = <0x1 0xe 0x304>;
                clocks = <0x8>;
        };

but there is no corresponding driver in the kernel (anymore).
It would seem it got removed in Linux 3.11
