Subject: [PATCH v4 1/2] dt-bindings: arm: rockchip: add RK3588 DP carrier from Theobroma Systems

From: Heiko Stuebner <heiko.stuebner@...rry.de>

The DisplayPort carrier is a very simple baseboard only providing serial,
ethernet and a displayport output.

But its main functionality is that it routes the Analogix eDP controller
to this DisplayPort output, which allows to test that controller simply
by hooking it up to a suitable monitor.
