gpio_type = 1 means that the board has a shared mic-in/line-in while
gpio_type = 2 means that the board has a shared side-out/line-in.
With i2c_adc=1, the driver adds some capture volume controls, phone,
mic, line-in and aux. Check whether these controls really work.
Also, spi_dac=1 adds the mute switch for each analog output, front,
rear, etc. Also check whether this works properly.
If everything is checked, please submit a patch to merge to the
upstream. See Documentation/SubmittingPatches in linux kernel tree
for details.
thanks,
Takashi
