Message:

OLPC ARM - Now that all TWSI child devices have been converted to use the new factoring, removed the old top-level /twsi node from the device tree and removed the global TWSI driver code. The only global references to twsi are now in the suspend/resume code (to be fixed) and an incidental one in MFPR pin attributes.

     3\ We omit nodes for unconnected TWSI channels 
     4\ The unit# properties are chosen so that GPIO I2C nodes get lower addresses. 
     5\ Some Linux drivers expect to find devices on specific I2C bus numbers.
