The addition of two new audio devices is proposed. These two devices are needed for the ASoC CPU and machine drivers for HDMI audio on OMAP4.
Implementation of ASoC HDMI audio drivers can be found here: http://mailman.alsa-project.org/pipermail/alsa-devel/2011-May/039758.html Implementation of DSS patches to support HDMI audio can be found here: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg49011.html This implementation is based on on: * OMAP4: DSS2: Add dss_dss_clk opt clock for OMAP4, by Sumit Semwal (http://gitorious.org/linux-omap-dss2/linux/commit/0da5637569bb9bf93e6930cd1c3b452eede50ba2) * Kernel 2.6.39-rc7 (git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git v2.6.39-rc7) The complete implementation, with devices, DSS and ASoC parts, is available at: git://gitorious.org/omap-audio/linux-audio.git ricardon/topic/hdmi-audio-v2 Validation was performed on HDMI TV. Penguins were present on the display and audio playback was performed with aplay at 32, 44.1 and 48kHz with S16_LE and S24_LE sample formats. Validation was performed on SDP4430 ES2.1 and ES2.2 and Panda ES2.1 and ES2.0.
