Tested with the spi-bcm2835aux driver and it works perfectly.
I will now post the latest incarnation of the driver for inclusion.

I have also tested with the uart1 and it works in principle.

Note that there is one issue (as mentioned elsewhere) with uart1:
the 8250 serial driver has a (hardcoded) internal clock divider 16,
while the hardware has an internal divider of 8.

This results in baud rates that are a factor of 2 higher than requested.
