Make sure we don't end up with an invalid CLKDIV=0 in case someone specifies 20kHz SCL or less (5 * 1024 / 20 = 0x100).

I2C_CLASS_ALL is almost never what bus driver authors really want. These i2c classes are really only about which devices must be probed, not what devices can be present. As device drivers get converted to the new i2c device driver model, only a few device types will keep relying on probing.

Blackfin TWI controller hardware pin should be requested from GPIO port controller Before BF54x, there is no need to do this. But as long as BF54x and BF52x are supported by this generic driver, the missing pin mux operation should be added.

Remove this unneeded mutex. Indeed it was used to serialize access to the hardware, but this is already done by the i2c-core layer, see 'bus_lock' mutex used by i2c_transfer().
