davinci_soc_platform_register and davinci-pcm-audio question

[Angelo Dureghello <angelo70@gmail.com>]

Dear all,

i am referring to this patch:

[PATCH V2 1/6] ASoC: davinci: davinci-pcm does not need to be a 
plaform_driver

i am working on a board, based on am1808(da850) cpu and codec wolfson 
wm8758 (created based on wm8985.c)
using mcbsp with a custom soc machine is actually broken,

This moving from kernel 3.5.1 to 3.17.

Alsa card is loaded correctly, but i can hear no sound:

omap_rtc omap_rtc: setting system clock to 2014-10-15 15:46:57 UTC 
(1413388017)
ALSA device list:
   #0: barix-ipam390
UBIFS: background thread "ubifs_bgt0_0" started, PID 1071
UBIFS: recovery needed

In the patch, seems "davinci-pcm-audio" is no more a driver.
And i should use "davinci_soc_platform_register" to have the pcm helper 
available.

But i don't understand in where i have to call this function.

Every help is appreciated.
