> -Can I2C clock be defined on device basis like at SPI?
Yes, I think it should be possible to change the bus speed when the device
takes over the mastership of the bus, I shall look into that.

I can't see any way to translate the SCL/SDA values that are need to calculate
the i2c speed into the MUL + ICR values that need to go into the frequency
divider register; the RM just provides a one big LUT for this.
