Re: Palmas wtchdog driver?

Hi Tony, I had the OMAP5 running very very hot by a kernel hang (most likely a spinlock). And I wondered if there is no safety mechanism (watchdog timer).

I did a little research and there seems to be no WDT driver for the Palmas in mainline.

There was something:

https://lore.kernel.org/patchwork/patch/367777/

but it seems it did not arrive upstream. Any reasons or problems with the driver? Or a newer version sitting in some git?

Sorry no idea. Maybe check if it's similar to the drivers/watchdog/twl4030_wdt.c?

Note that some devices just use drivers/watchdog/omap_wdt.c that is wired to the PMIC used. So maybe the Palmas WDT was just forgotten if it was not needed?

Regards,

Tony
