[alsa-devel] [PATCH] [RFC 9/13] Intel SST sound card vendor0 module
Vinod Koul
vinod.koul at intel.com
Fri Jul 3 08:23:21 CEST 2009
This adds the support for vendor PMICs for widget control
and configurations. The MID platform supports three
different vendor implementation of PMIC.
The sound card, ie all analog components like DAC,
ADC, mixer settings are different for three vendors. This
patch implements these settings for one of the vendor.
