drm/tegra: sor: Use DP link training helpers

2019-10-28T10:18:53+00:00

Make use of the DP link training helpers to implement full and fast link
training. While at it, refactor some of the code and remove various code
sequences that are not necessary.

drm/tegra: sor: Support for audio over HDMI

2018-12-03T15:37:26+00:00

This code is very similar to the audio over HDMI support on older chips.
Interoperation with the audio codec is done via a pair of codec scratch
registers and an interrupt that is raised at the SOR when the codec has
written those registers.

drm/tegra: sor: Support HDMI 2.0 modes

2017-12-13T13:36:37+00:00

In addition to using the SCDC helpers to enable support for scrambling
for HDMI 2.0 modes, take into account the high pixel clocks when
programming some of the registers.

drm/tegra: sor: Add Tegra186 support

2017-12-13T13:36:36+00:00

The SOR found on Tegra186 is very similar to the one found on Tegra210
and earlier. However, due to some changes in the display architecture,
some programming sequences have changed and some register have moved
around.

drm/tegra: sor: Do not support deep color modes

2016-07-04T09:33:21+00:00

Current generations of Tegra do not support deep color modes, so force
8 bits per color even if the connected monitor or panel supports more.

drm/tegra: sor: Add HDMI support

2015-08-13T11:49:37+00:00

The SOR1 introduced on Tegra210 supports HDMI 2.0 and DisplayPort. Add
HDMI support and name the debugfs node after the type of SOR. The SOR
introduced with Tegra124 is known simply as "sor", whereas the
additional SOR found on Tegra210 is known as "sor1".

drm/tegra: sor: Rename registers for consistency

2015-08-13T11:47:50+00:00

The TRM lists indexed registers without an underscore to separate name
from index. Use that convention in the driver for consistency.

While at it, rename some of the field names to the names used in the
TRM.

drm/tegra: sor - Add CRC debugfs support

2014-06-05T21:09:17+00:00

The SOR allows the computation of a 32 bit CRC of the content that it
transmits. This functionality is exposed via debugfs and is useful to
verify proper operation of the SOR.
