From a8fe58cec351c25e09c393bf46117c0c47b5a17c Mon Sep 17 00:00:00 2001 From: Maruthi Bayyavarapu Date: Tue, 22 Sep 2015 17:05:20 -0400 Subject: drm/amd: add ACP driver support This adds the ACP (Audio CoProcessor) IP driver and wires it up to the amdgpu driver. The ACP block provides the DMA engine for i2s based ALSA driver. This is required for audio on APUs that utilize an i2s codec.
