From cb6f58449683f7b30a6a8718bac5475c39b291d8 Mon Sep 17 00:00:00 2001 From: Simon Ser Date: Wed, 13 Jan 2021 00:33:19 +0100 Subject: backend/drm: add support for the subconnector property The subconnector property indicates the connector sub-type. This is useful because that usually indicates what kind of connector the user has plugged in to their monitor, e.g. a DisplayPort-to-DVI cable will indicate a DVI subconnector. Also some laptops have non-DP connectors that are internally linked to a DP port on the GPU. Set the output description accordingly.
