From 7ac0da8cd38cb09d0addf708a8abbb93cf325c68 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 14 Aug 2013 14:26:29 -0600 Subject: [PATCH] ASoC: tegra: support a Mic Jack in the Tegra+RT5640 machine driver Add a Mic Jack widget to the Tegra+RT5640 machine driver, and document this in the DT binding. This enables the DT to include the Mic Jack in the audio routing table, and hence enables capture of audio, in addition to the previously-working playback.
