From fff8491c8b8cce5fc9190e025d1a665f2ee71a4f Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Tue, 14 Aug 2012 12:07:56 +0300 Subject: ASoC: omap-twl4030: Simple machine driver for TI SoC with twl4030 codec Machine driver to handle simple devices using twl4030 as audio codec. The driver supports the following boards: - Beagleboard or Devkit8000 - Gumstix Overo or CompuLab CM-T35/CM-T3730 - IGEP v2 - OMAP3EVM All of these boards can be switched to use this driver since their setup is identical. Devicetree support for the omap-twl4030 machine driver also implemented.

Splitting asp header into Davinci platform specific header and Audio specific header helps to share them across platforms. Audio specific defines is moved to to common so that the header can be accessed by all related platforms. While here, correct the header usage (remove multiple header re-definitions and unused headers) and remove platform names from structures comments and enum. Also some some coding style errors.
