[U-Boot] Adding a composite device, how to structure ?

Wolfgang,

I would like to add support for the twl4030, a composite i2c device, found on the omap3 zoom's. The header file will be include/twl4030.h. How do you want the source to be structured ? 1. A single large file in drivers/i2c/twl4030.c

or device files added under a directory ?

2. drivers/i2c/twl4030/keyboard, drivers/i2c/twl4030/usb, drivers/i2c/twl4030/battery,

or just the common code in i2c and twl4030 devices in the places they usually go.

3. drivers/i2c/twl4030.c, drivers/usb/tw4030_usb.c etc ..

My guess is #3.
