Howard, thanks for picking up my laundry!

Is master mode working for you otherwise? Have you seen any sign
of bad dividers for the various clocks, or anything like that?

Regarding the pin configuration, I suppose the cleanest approach
would be to implement it as a pin control driver? Then you could
also expose the pins as gpios and  select the pin functions in a more
standard way, right? I wouldn't know where to start with that
though. I have the feeling that it would also mean that there would
have to be a mfd driver for the chip???

However, there is the issue that we don't need anything more from
the chip, so we're happy with the driver as is (assuming the overclocking
patch goes in as planned for 4.1).

Cheers,
Peter
