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.

Resending this patch after rebasing. Previous discussion can be found here [1]

Changes since v1:
- Rebased on latest kgene tree, test booting and s2r on SMDK5250 board.
- 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.

Since previous discussion ([1] above) there have not been any updates on
cause of this issue so I think this should go in:
Acked-by: Krzysztof Kozlowski <k.kozlowski@samsung•com>
Best regards,
Krzysztof
