Subject: I2C framework originally written by Steve C. Woodford and Jason R.
 Thorpe for NetBSD (r).

This framework supports various i2c master controllers:
- dumb bit-bang controllers
- a few styles of automated controllers that give you control
over sending start/stop conditions on the i2c bus
- automated controllers that are too smart for its own good,
giving software no control over start/stop conditions
- smbus controllers by emulating smbus protocol with i2c commands

i2c slave devices need their addresses to be specified in the kernel
config file, no device discovery presented.
