It may be possible to use your board specific data in your callbacks
directly rather than passing the board data to the driver and passing
it back, although it depends on the structure of your code.

I think the use of pdata->init should be made optional, as it doesn't
seem to be needed on most SoCs.

Yes, certainly. We continue to work on the driver and would be happy
to have our bugs fixed! ;-)

We have tested it, unfortunately I don't have any accurate performance
figures to hand. The perform seems to be in the expected range though.
