drm/tegra: hdmi: Enable audio over HDMI

2016-07-04T09:34:31Z

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

drm/tegra: hdmi - Disable LVDS mode

2014-06-05T21:09:25Z

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. Signed-off-by: Thierry Reding

drm/tegra: hdmi: Parameterize based on compatible property

2013-10-31T08:55:42Z

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. Signed-off-by: Thierry Reding

drm: tegra: Add HDMI support

2012-11-20T05:43:53Z

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 and many other people at NVIDIA were very helpful in getting the HDMI support and surrounding infrastructure to work.
