This set of patches add device tree support for the AC97 controller found on AT91SAM9263. The first two patches are minor cleanup, while the last ones add the actual support.
I just test the whole patch series, and find issues to work with device tree kernel. When we use dt kernel, no where assign the device id (so take it as "-1"), so when register devices, it will be /dev/snd/pcmC0D-1p and /dev/snd/pcmC0D-1c. So, the sound won't work.
The root cause is that when call "snd_pcm_new", it will pass "chip->pdev->id" as parameter.
So, I am thinking whether this should be fix in <sound/atmel/ac97c.c> or in <sound/core/pcm.c>
