From 7b20b2be51e1a9c250535e1a4df42e1cd20c7ecf Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Fri, 18 May 2018 13:56:00 +0100 Subject: ASoC: qdsp6: q6adm: Add q6adm driver This patch adds support to Q6ADM (Audio Device Manager) module in q6dsp. ADM performs routing between audio streams and AFE ports. It does Rate matching for streams going to devices driven by different clocks, it handles volume ramping, Mixing with channel and bit-width. ADM creates and destroys dynamic COPP services for device-related audio processing as needed. This patch adds basic support to ADM.
