I was giving zoom2 reference from kernel 3.8-rc5.

My board is not botting with linux-next ((next-20130211). So i have
taken omap-twl4030.c changes from next-20130211
and merged into 3.8-rc5 as it does have. But missed changes for
twl4030.c. With these all changes it is working for me now .
Sorry for noise.

I am really thanks for this.
Anil
