Subject: [PATCH 1/2] arm64: dts: rockchip: add HDMI support to rk3588-tiger-haikou

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

The Haikou baseboard has an hdmi output port, which is connected
via the Q7 connector to the hdmi0 controller of the rk3588.

Add the necessary plumbing to enable it using the recently merged
hdmi-qp controller.
