[alsa-devel] [PATCH 2/3] ASoC: Intel: kbl_da7219_max98357a_rt5660: Add a new codec rt5660

Hui Wang hui.wang at canonical.com
Thu Dec 6 15:52:06 CET 2018


The new Dell IoT platform uses kabylake + alc3277 codec, and alc3277
shares the driver with the codec rt5660, here we choose the
closest machine driver kbl_da7219_max98357a, and based on this driver,
we add a new codec rt5660 to it.

The audio design on this IoT platform is as below:
 - Intel kabylake platform
 - connect the codec ALC3277 via SSP0
 - line-out and line-in with Micbias jacks
 - line-out mute control and jack detection of line-out and line-in
 - two HDMI ports with audio capability
