Colibri T20 AC97 initialization issue

Colibri T20 AC97 initialization issue

[Stefan Agner]

Hi,

Just tried to run v3.14-rc6 on a Colibri T20. Anybody knows whats going
on here?

[    3.308695] tegra-snd-wm9712 sound.3: ASoC: CPU DAI (null) not
registered
[    3.317927] tegra-snd-wm9712 sound.3: snd_soc_register_card failed
(-517)
[    3.325352] platform sound.3: Driver tegra-snd-wm9712 requests probe
deferral

I noticed that Lucas removed cpu_dai_name in a recent commit
(58e354be337dff43dbb66c4564bb9479354cc5dd), however even with that
property ASoC core claims that the DAI is not registred. I checked the
configuration, CONFIG_SND_SOC_TEGRA20_AC97 and
CONFIG_SND_SOC_TEGRA_WM9712 is set...

You'll need my second patch to move the clock handling to the machine
driver for AC'97 to work. I keep forgetting to resend and follow up on
this. I will send out another version today, if not please ping me
again.
