From c0cc3f1665256b7cfdc1d581f997dcea1af71405 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 28 Sep 2012 16:50:15 +0100 Subject: ASoC: wm8994: Allow a delay between jack insertion and microphone detect This can be used to provide some additional settling time to ensure that we don't start microphone detection while the microphone pin is connected to one of the headphone pins.
