[ALSA] soc - ASoC 0.13 pxa2xx AC97 driver
Browse files Browse the repository at this point in the history 
This patch updates the pxa2xx AC97 driver to the new API in ASoC 0.13.
Changes:-
o Removed DAI capabilities matching code in favour of manual matching in
the machine drivers.
o Added DAI operations for codec and CPU interfaces.
o Added pxa2xx-ac97.h header
