From 8c5b842b8352494d4a258311866b6dc7c2cb11eb Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 17 Apr 2012 20:49:05 +0100 Subject: [PATCH] ASoC: wm8994: Keep AIF3 tristated when not in use Since AIF3 shares clock signals with other audio interfaces in order to ensure it doesn't drive undesirable clocks we need to tristate it. Rather than forcing the machine driver to do so have the driver do this.
