From b14c917409f47dbfdff93e69effd6740f6a809f7 Mon Sep 17 00:00:00 2001 From: Nicolas Boichat Date: Thu, 16 Jul 2015 13:42:33 +0800 Subject: [PATCH] ASoC: rt5645: Update dapm pins when the card is not instantiated yet This makes sure the dapm state is consistent when the card is instantiated. However, if the card is not instantiated yet, we still update the registers manually in the "jack in" case, so that we can immediately report if a mic is present or not. Disabling "Mic Det Power" after detection, and on jack out, can wait until the card gets instantiated.
