From ac29a8f41740186aee601de99c729530e37ca77c Mon Sep 17 00:00:00 2001 From: Adam Thomson Date: Fri, 16 Dec 2016 11:05:02 +0000 Subject: [PATCH] ASoC: da7218: Set DAI output pin high impedance when not in use For TDM mode, the I2S data out line can be shared between mutliple codecs. In this scenario, only the active codec should be using the line, and all others should be high impedance. However, currently in the driver this configuration isn't set when capture is inactive, and the line remains driven. This patch updates the AIF_OUT widget to set the DAI output pin of the device as high impedance when not in use.
