From a5461fd6c8f70b3d897f5f76612e890ad47a5b93 Mon Sep 17 00:00:00 2001 From: Oder Chiou Date: Tue, 25 Oct 2016 19:27:26 +0800 Subject: ASoC: rt5514: Add the DMIC initial delay to wait it ready. Due to the DMIC that needs time to initial after the MCLK is provided, the field of delay time is implemented by the platform data.
