Hi,

Hi,

Yadwinder, please don't miss [PATCH 1/2] in subject, so that my e-mail client
can't filter wrong ;)

With default config on smdk5250 latest tree throws below message :

and hangs randomly because it reads wrong temperature value.

I can't figure out any direct relation between LDO10 and TMU from board
schematics which I have. So making LDO10 always-on to fix issue for now.

Hmm...strange, I also can't see any relations now...but I need to contact to
hardware guy before applying this, this fixes the problem though.


By any chance you got time to check with HW engineer, as issue is there without this patch, SMDK5250 fails to boot and hangs.

Tested this on SMDK5250 board, system boot is fine now, hence
