Hi Vaibhav
Thank you for your comments.

I've taken all your comments, apart from two:


> >  #ifdef CONFIG_VIDEO_OMAP3
> > +#ifndef CONFIG_TWL4030_CORE
> > +#error "no power companion board defined!"
> > +#endif
> [Hiremath, Vaibhav] Do we really required to do this?

Well its not required, but my feeling is that it could be useful.
It was originally around every instance of the twl4030_i2c_write_u8() function and that was quite ugly.
So I moved it to the top here to cover all the sensors that the SDP supports.
I will reconsider if you feel it's a big issue.

I will resubmit shortly.
Thanks
dom
