AM1808, mcbsp audio on kernel 3.17.0

Hi all,

i am trying to have the pcm audio working moving from kernel 3.5.1 to 3.17.

I ported my soc machine based on wolfson wm8758 codec, but the audio is muted, i just hear some "clicks" on start and stop playing.

Also, come alsa mixer channels, as "Capture Volume" and some other are broken (I/O error accessing them).

A main change on kernel 3.17 is that "davinci-pcm-audio" is no more a platform driver.

A new function, "davinci_soc_platform_register()" seems need to be called, but if i call it from my soc machine card driver, nothing happen.

If someone have experience, every suggestion is welcome.

Regards
