I'd vote against creating a drivers/i2c/chips directory.  I believe this
directory is deprecated in the Linux kernel and they'd prefer drivers be
put in the proper driver/<subsystem> directory.  I'd vote to follow this
convention in U-Boot too.

I'm not familiar with the device or what features you plan on supporting
so I can't speak to whether it'd fit better in drivers/power,
drivers/misc, somewhere omap3/board specific, etc.

Best.
