Hi,
daveshah mentioned on IRC that the PALMAS has a watchdog that can reset the system in case the OMAP5 does a lock up.
Yes, I think it should be enabled.
Apparently, it was enabled on an older kernel or bootloader TI released for the uEVM, but it's not enabled in our current setup.
The problem is: In case the OMAP5 locks up, it can run at full power and run REALLY hot - which could damage the battery.
Does anyone know how to enable that watchdog?
It appears as if the ti,palmas-wdt driver did not arrive in mainline:
patch 4/12 and 5/12 apply cleanly on v3.7 so we can think about forward-porting them.
If my memory would be better, I had remembered that we already have that:
https://git.goldelico.com/?p=letux-kernel.git;a=shortlog;h=refs/heads/letux/...
But it seems to be broken and not enabled.

I have no idea why. Maybe ask Tony?
BR, Nikolaus
