From 503ae5e036824935d9e214b9819a618499733bdf Mon Sep 17 00:00:00 2001 From: Misael Lopez Cruz Date: Thu, 24 Apr 2014 14:01:44 +0200 Subject: [PATCH] ASoC: core: Add helpers for dai link and aux dev init Separate DAI link and aux dev initialization in preparation for DAI multicodec support. Since aux dev will remain using single codecs but DAI links will be able to support multiple codecs. No functional change.
