[PATCH v3 0/5] Support bridge/connector by Tegra HDMI

[PATCH v3 0/5] Support bridge/connector by Tegra HDMI

[Svyatoslav Ryhel]

This patch adds support for the bridge/connector attached to the
HDMI output, allowing to model the hardware properly. It keeps
backwards compatibility with existing bindings and is required
by devices which have a simple or MHL bridge connected to HDMI
output like ASUS P1801-T or LG P880/P895 or HTC One X.

Tested on ASUS Transformers which have no dedicated bridge but
have type d HDMI connector directly available. Tests went smoothly.

---
Changes from v2:
- added missing descriptions to tegra dc and hdmi yamls
- fixed "Warning (unit_address_vs_reg): /host1x@50000000/
  dc@54200000/rgb/port@0: node has a unit name, but no reg or
  ranges property"
- dropped reg from port to avoid same warning with hdmi ports

Changes from v1:
- no changes, re-sending

Just to make sure, what properties are you using from this? Usually 
we'll list them though not a hard requirement. If none, then you just 
need to ref graph.yaml#/properties/port instead and can drop the rest.

In the indented cases, it's easier to read if this is before 
properties/patternProperties.

I would prefer to drop this and mark "nvidia,panel" as deprecated. 
Eventually I plan to add a mode to the tools to warn on using deprecated 
properties. Having both could be perfectly fine too. You have the 
"nvidia,panel" for compatibility with an old OS version and 'port' to 
work with newer users.

Move this up too.

currently, just bus-width is used in devicetrees, but I don't think that
it is needed at the moment. So perhaps the property can be dropped.

The reason for adding this was that just one of them can be utilized at
the same time. Having both could potentially break the display output.
I think that all the other nvidia,* properties could marked as
deprecated as well because they don't seem to be doing much since commit
d9f980ebcd01 ("drm/tegra: output: rgb: Wrap directly-connected panel
into DRM bridge").

[PATCH v3 4/5] drm/tegra: output: hdmi: Support bridge/connector

[Svyatoslav Ryhel]

From: Maxim Schwalm <maxim.schwalm@gmail.com>

Some Tegra device-trees may specify a video output graph, which involves
MHL bridge/simple bridge and/or connector framework. This patch adds
support for the bridge/connector attached to the HDMI output, allowing
us to model the hardware properly.

Inspired by: 29efdc2 ("drm/tegra: output: rgb: Support LVDS encoder bridge")
