This patch is based on top of kernel 3.8-rc5 and
the following patches.

Peter Ujfalusi:-
ASoC: twl4030: Correct the support for Voice port
ASoC: twl4030: Convert MICBIAS to SUPPLY widget
ASoC: omap-twl4030: Add support for routing, voice port and jack detect

Anil Kumar:-
ARM: dts: add minimal DT support for DevKit8000
https://patchwork.kernel.org/patch/2122461/

-Tested for playback and capture on Devkit8000.

 Test process:-

 #amixer set 'PredriveR Mixer AudioR2' on
 #amixer set 'PredriveL Mixer AudioL2' on
 #amixer set PreDriv 100 unmute
 #amixer set 'DAC2 Digital Fine' 100
 #amixer cset numid=27 1
 #arecord | aplay
