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. Signed-off-by: Thierry Reding <treding@nvidia.com>
