From aa5ae424952fe2d1c2ca2340a433c3e3407262f7 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 12 Mar 2013 17:03:42 -0600 Subject: ARM: tegra: enable audio on Dalmore Dalmore uses the RT5640 audio CODEC. Instantiate this on the I2C bus. Enable the relevant Tegra I2C controller. Add the top-level "sound" node to hook everything together, and provide a "sound card" device.
