[PATCH v2 4/6] arm64: dts: qcom: x1e80100-vivobook-s15: add HDMI port

[Maud Spierings via B4 Relay <devnull+maud_spierings.hotmail.com@kernel.org>]

From: Maud Spierings <maud_spierings@hotmail.com>

Enable the HDMI port on left side of the laptop.

The display signal is routed through a simple Displayport to HDMI
bridge.
