From 084011615c1c885232e8d1fb5cc3f85c9d880d14 Mon Sep 17 00:00:00 2001 From: Eric Millbrandt Date: Thu, 20 Sep 2012 10:36:44 -0400 Subject: ASoC: fsl: pcm030-audio-fabric use snd_soc_register_card Convert pcm030-audio-fabric to use the new snd_soc_register_card api instead of the older method of registering a separate platform device. Create the dai_link to the mpc5200_psc_ac97 platform using the device tree. Convert the pcm030-audio-fabric driver to a platform-driver and add a remove function.
