2009-06-19i2c: Add a sysfs interface to instantiate devicesJean Delvare
Add a sysfs interface to instantiate and delete I2C devices. This is primarily a replacement of the force_* module parameters implemented by some i2c drivers. These module parameters were implemented internally by the I2C_CLIENT_INSMOD* macros, which don't scale well. This can also be used when developing a driver on a self-soldered board which doesn't yet have proper I2C device declaration at the platform level, and presumably for various debugging situations.

2009-03-28i2c: Document the different ways to instantiate i2c devicesJean Delvare
On popular demand, here comes some documentation about how to instantiate i2c devices in the new (standard) i2c device driver binding model. I have also clarified how the class bitfield lets driver authors control which buses are probed in the auto-detect case, and warned more loudly against the abuse of this method.
