Hi!

This series implements BCLK master modes for the pcm512x driver. It has
only been tested with the pcm5142 chip, but they are from the same family
and should be compatible. I have mainly used the spec for the newer
pcm5242 chip (also from the same family) as it fills in a lot of blanks
in the pcm512x/pcm514x specs.

The code has also seen most of its testing in a 3.10 environment, so
there might be some forward-porting warts. But it is able to play sound
in 3.18 as well, and most of the changes have little to do with anything
but the clocking in the chip itself.

Cheers,
Peter
