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. |
