I'll leave taking a proper look until you have cleared up the issues Alan pointed out.
But as I was taking a quick look...

Firstly I concur entirely with Alan in that most of the sysfs stuff should be
platform data for an input driver.

Perfectly good irq element in i2c_board_info structure. This is exactly what
it is normally used for.

Would be nice to have some docs on that platform data struct as well.
Most of it is fairly obvious, but data_odr_init etc aren't!
