From bf7c6e6ccbde22c96c5c1e5cec08740c31229df1 Mon Sep 17 00:00:00 2001 From: Barry Song <21cnbao@gmail.com> Date: Thu, 16 May 2013 14:08:07 +0800 Subject: ASoC: omap-hdmi-codec: make the driver common for other SoCs to support HDMI on CSR SiRFprimaII and atlasVI, we need one more HDMI pseudo codec, rather than add a new driver, we can make omap HDMI codec common for other SoCs as well. then the omap-hdmi codec becomes a generic HDMI pseudo- codec as HDMI audio features depend on HDMI specification not on SoCs.
