Same answer as last year.

                                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
As I did with my imx i2c driver last year....Yes, this I2C controller is 
mostly the same than the one in the MPC family and mostly the same the ones 
we can find in the MCX family (i.MX21/27, i.MX31?). But it seems there is 
noone who is able to write such a generic driver.
