[PATCHi v2] ARM: dts: Fix bootup issue on smdk5250
From: Pankaj Dubey
Date: Tue Aug 18 2015 - 02:29:42 EST
From: Yadwinder Singh Brar <yadi.brar01@xxxxxxxxx>
With default config on smdk5250 latest tree throws below message :
[ 2.226049] thermal thermal_zone0: critical temperature reached(224 C),shutting down
[ 2.227840] reboot: Failed to start orderly shutdown: forcing the issue
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.

- Removed Yadwinder Singh's Samsung's email id as it's no more valid.
- Added my Signed-off-by for touching this file and patch.
