[ALSA] soc - ASoC 0.13 pxa2xx AC97 driver
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 Signed-off-by: Liam Girdwood <lg@opensource.wolfsonmicro.com> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
