Thanks, I tried forcing dma mode and I got the following probe issue
on a mx28evk running today's linux-next:

[    6.403193] mxs-sgtl5000 sound.12: ASoC: CODEC (null) not registered
[    6.412175] mxs-sgtl5000 sound.12: snd_soc_register_card failed (-517)
[    6.425582] platform sound.12: Driver mxs-sgtl5000 requests probe deferral
[    6.434043]  mmcblk0: p1 p2 p3
[    6.439586] stmp3xxx-rtc 80056000.rtc: setting system clock to
2013-04-23 21:00:42 UTC (1366750842)
[    6.458141] mxs-sgtl5000 sound.12: ASoC: CODEC (null) not registered
[    6.464773] mxs-sgtl5000 sound.12: snd_soc_register_card failed (-517)

If I run linux-next with 2f769432d8554 reverted then I get a 23
seconds delay in the probe (1 second for each sgtl5000 register
write).
