Hello, The ASoC HDMI codec used to be embedded in the DSS HDMI driver. In order to give the OMAP HDMI code a more logical arrangement and to remove some dependency breaks[1][2], such ASoC HDMI codec was removed[3]. Instead, the DSS HDMI audio functionality[4] is now provided through the new DSS device driver audio interface [5]. Hence, the ASoC HDMI support for OMAP needs to be changed to use this new DSS device driver audio interface. Under this new approach: * The HDMI audio functionality provided by the OMAP is now regarded as a CPU DAI rather than a codec. Hence, the CPU DAI will perform the operations that were performed previously by the codec (using the DSS dev driver audio interface). * A new ASoC HDMI OMAP codec is introduced as a dummy component. In the future, this component will examine the features supported by the sink and limit the number of channels, sample rates and formats that are exposed to the user. Also, this set of patches paves the way to the introduction of the HDMI audio functionality for OMAP5. The goal is to use the same set of ASoC drivers for OMAP4 and OMAP5 (DSS will be in charge of selecting the correct set of functions at run time). For this, several patches are submitted for: * Generalizing the build files to encompass not only OMAP4. * In the HDMI sound card driver, renaming the the functions and structures from omap4_ to omap_. This set includes the suggestions and improvements that Mark Brown kindly provided some time ago [6][7]. Please note that this set of patches will not build unless the patches from [4], [5] and [8] are present. All these patches have been accepted and should be upstream for K3.5.
