From 23037bbd9661b53236ebe934c77952e8f73f1c7a Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 27 Mar 2013 16:53:20 -0600 Subject: [PATCH] ARM: tegra: enable audio on Beaver Beaver uses the RT5640 audio CODEC. Instantiate this on the I2C bus, and add the top-level "sound" node to hook everything together and provide a "sound card" device.
