[alsa-devel] [PATCH 6/9] ASoC: Intel: Skylake: Initialize and load DSP controls
Subhransu S. Prusty
subhransu.s.prusty at intel.com
Fri Aug 7 21:36:21 CEST 2015
From: Jeeja KP <jeeja.kp at intel.com>
Initialize and creates DSP controls if processing pipe capability
is supported by HW. Updates the dma_id, hw_params to module param to
be used when DSP module has to be configured.
