Hi,
exynos4 tmu is already merged 3.2-rc
you can find it at below message and latest git kernel
http://www.spinics.net/lists/lm-sensors/msg33872.html
Thank you,
Kyungmin Park
ok I will rebase my work on top of sensor
Thanks for pointing this out.

This patch adds support for thermal sensor driver. It supports 3 trigger
level. The first 2 level are warn and monitor temperature level. The
third critical trigger level resets the system. The threshold
change information is sent to the thermal interface layer.
