[alsa-devel] [PATCH v5 04/12] ASoC: Intel: mrfld: add bytes control for modules
Subhransu S. Prusty
subhransu.s.prusty at intel.com
Tue Sep 2 14:35:59 CEST 2014
From: Vinod Koul <vinod.koul at intel.com>
This patch add support for various modules like eq etc for mrfld DSP.
All these modules will be exposed to usermode as bytes controls.
