The old method carried along with board-pbp-add-dp-alt-mode.patch only
makes typec work in one(normal) orientation. This patch introduces a
proper extcon driver and makes the workaround cleaner, so orientation
switch is working.
Improvements:
- type-c DP on rk3399 works with both orientations
- type-c USB 3.0 on rk3399 works with both orientations, with minor
issues, see below
Caveats:
- Powered USB-C hubs may be not recognized, and can be worked around by
loading a gadget driver, or manually toggling the mode once for each
connection.
- Some dual-role devices(phone, tablet) may be not recognized.
Affected boards:
- TinkerBoard 2/2S
- Pinebook Pro
- NanoPC T4
- Orange Pi 4
- Orange Pi 4 LTS
Tested on tinkerboard 2s. This patch contains other minor fixes for
tinker2's device tree, including adding a missing fan node, adding color
labels to leds.
The 2 patches adding dp support for nanopc t4 and pinebook pro are also
updated accordingly.
The device trees of Orange Pi 4 / 4 LTS are also updated to match the
new implementation.

From the Kconfig:
```
Preload default EDID (Extended Display Identification Data)
branded by Linux Foundation that exposes display modes up
to 4k@30Hz, which have best compatibility with HDMI transmitters.
Enabling this option is recommended for a non-production use-cases.
It will make driver usable out-of-the-box.
For a higher display modes you will need to load customized EDID
from userspace using v4l2-ctl tool or by other means.
Without enabling this option driver will be practically
non-functional until EDID will be loaded from userspace.
Which is a wanted behavior when using this driver in a
commercial product that should utilize own branded EDID.
