-Subject: [PATCH] drm/vc4: Replace HDMI force-connected with an EDID probe.
-
-The force-connected started out because I didn't know how to read the
-HPD pin successfully, which required the hpd_active_low check and
-getting the correct active level into the DTs.  It stayed because we
-don't have the Pi3's HPD line exposed to Linux, so this was the only
-way to bring up graphics on it.
-
-However, with the DSI panel support now present, users want to be able
-to run DSI-only systems, and forcing HDMI on is interfering with
-default screen configurations.  Work around the Pi3's missing HPD by
-probing the DDC on I2C and see if it's present at all.
