Hi, This set of patches is inteded to prepare the HDMI driver to implement the DSS device driver interface for audio proposed here: http://www.spinics.net/lists/linux-omap/msg67303.html In preparation for that, it removes the current ASoC HDMI codec driver and decouples HDMI audio build configuration from ASoC. Instead, a config option may be selected by the parties interested in the HDMI audio functionality. The last patch effectively implements the DSS audio interface. Also, this set prepares the HDMI driver for the introduction of the OMAP5 HDMI audio functionality by further abstracting the portions of code that are generic to all HDMI implementations (e.g, N/CTS params calculation). Also, an IP-dependent audio configuration function is introduced as an HDMI IP operation; this function takes IP-independent parameters and is intended to be implemented for each individual IP. For the specific case of OMAP4, the configuration of the IEC-60958 channel status word is expanded to provide more flexibility. Also, some duplicated IEC-60958 definitions are removed to, instead, reuse the definitions provided in asound.h The CEA-861 definitions are not yet added to asound.h. I will send a patch for that to alsa-devel. The changes for OMAP4 configuration expand the current support to cover more audio sample rates: 32, 44.1, 48, 88.2, 176.4 and 192 kHz. Audio sample world length of 16 through 24 bits as well as up to 8 audio channels. These changes are based on the 3.3 Linux kernel plus the patches for the audio MCLK selection (http://www.spinics.net/lists/linux-omap/msg64302.html). Validation was performed using Onkyo TX-SR508 and Yamaha RX-V367 AV receivers.
