Subject: [PATCH v3 0/2] Add RK3588 Tiger DisplayPort carrier

A board that allows easy testing of the Analogix eDP controller on the
RK3588. Requires Damon's recent work on allowing bridges in the
Rockchip variant of the controller driver [0].

Concerning displays, my current setup is

  DP-carrier -> DP-port -> DP-to-eDP converter from Aliexpress -> eDP panel

which produces a nice 1080p image, but it seems Quentin's experience was
not as nice, as he reported in v2 [1] that his two test monitors produced
dfferent tints, but not real output with:

green tint on a Iiyama ProLite XU2294HSU and purple tint on a Dell P2319H


changes in v3:
- rebase on top of 6.17-rc1
- still should wait on the analogix bridge support

changes in v2:
- collect Ack/Review for binding
- address Quentin's comments
  - sorting in Makefile and dp-connector properties
  - ethernet alias
  - drop data-lanes comment
