Thierry Reding 2ccb396e9d drm/tegra: hdmi: Enable audio over HDMI
In order to use the HDA codec to forward audio data to the HDMI codec it
needs the ELD that is parsed from the monitor's EDID.

Also implement an interoperability mechanism between the HDA controller
and the HDMI codec. This uses vendor-defined scratch registers to pass
data from the HDMI codec driver to the HDMI driver (that implements the
receiving end of the HDMI codec). A custom format is used to pass audio
sample rate and channel count to the HDMI driver.

Thierry Reding 9cbfc73e11 drm/tegra: hdmi - Disable LVDS mode
Disable LVDS mode according to register documentation. It seems like
this has no effect on the operation of HDMI, but it's probably a good
idea to do this anyway.

Thierry Reding 59af0595f4 drm/tegra: hdmi: Parameterize based on compatible property
Use a structure to parameterize the code to handle differences between
the HDMI hardware on various SoC generations. This removes the need to
clutter the code with checks for individual compatible values.

Thierry Reding edec4af4c3 drm: tegra: Add HDMI support
This commit adds support for the HDMI output on the Tegra20 SoC. Only
one such output is available, but it can be driven by either of the two
display controllers.

A lot of work on this patch has been contributed by NVIDIA's Mark Zhang
<markz@nvidia.com> and many other people at NVIDIA were very helpful in
getting the HDMI support and surrounding infrastructure to work.
