ALSA SoC needs to know connected DAI ID for probing. Using the new audio-card-graph approach, ports/endpoints are used to describe how the links are connected. Unfortunately, since ports/endpoints are used as well for video linkages, there are some issues mixing the port ids to the two (video and audio) namespaces. To solve this issue, this patch adds new .get_dai_id callback on hdmi_codec_ops. The will assume that HDMI audio out will be connected to reg = <2>. This will then be remapped to the ALSA SoC side will as DAI 0. Allowing the adv7511's hdmi audio support to be used with the audio-card-graph. Credit to Kuninori Morimoto who's patch to dw-hdmi-i2s-audio.c was what this was mostly copy-pasted from.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
