The uclass implements the same operations as the current I2C framework but
makes some changes to make it fit driver model better:

- Remove the chip address from API calls
- Remove the address length from API calls
- Remove concept of 'current' I2C bus
- Drop all existing init functions

OMAP24xx I2C: Add support for set-speed 2014-02-20T05:48:23+00:00 Hannes Petermaier oe5hpm@oevsv.at 2014-02-03T20:22:18+00:00 d5243359e1afc957acd373dbbde1cf6c70ee5485 Adds support for set-speed on the OMAP24xx I2C Adapter. Changes to omap24_i2c_write(...) for polling ARDY Bit from IRQ-Status. Otherwise on a subsequent call the transfer of last byte from the predecessor is aborted and therefore lost. For exmaple when i2c_write(...) is followed by a i2c_setspeed(...) (which has to deactivate and activate master for changing psc,...). Minor cosmetical changes.
