Updated TLV320AIC31xx Driver for 3.4 kernel release

Hi Mike,

We are using the same codec ( TLV310AIC3110 ). Did you get the updated drivers?

We have initial ramping noise during the playback. Did you face such issues?

Hi Karthikeyan,

I tried converting the PandaBoard drivers from (Linux 3.0 kernel):
http://gitorious.org/ti-codecs/ti-codecs/commits/aic31xx_panda

My commits starts with this:
https://github.com/KFire-Android/kernel_omap_otter-common/commit/f499c1a072ed12659fe49967bb10a9f318e08c80

And the rest of the cleanup is probably here:
https://github.com/KFire-Android/kernel_omap_otter-common/commits/p-android-omap-3.4/sound/soc

That being said, it was mostly unsuccessful.  If I leave the PIN_SWITCH controls active in the kernel, I get hung up when alsa queries them:

https://github.com/KFire-Android/kernel_omap_otter-common/blob/p-android-omap-3.4/sound/soc/omap/omap4_panda_aic31xx.c#L315

So right now I get the slight ramp up noise and no audio when testing playback.

I ended up getting very busy and didn't come back to the project to debug it.

Hope that helps,

Mike

Thanks Mike.

I picked and modified the drivers from the git link. But still I could not remove the initial slight ramp up noise during the playback. Let me debug the driver for possible issues.

Karthik,

If you have any public sources, I would love to compare with your work.  On my kernel, I also have some complication with ABE code for use in Android.
