-Subject: [PATCH] drm/vc4: hdmi: Rely on interrupts to handle hotplug
-
-DRM currently polls for the HDMI connector status every 10s, which can
-be an issue when we connect/disconnect a display quickly or the device
-on the other end only issues a hotplug pulse (for example on EDID
-change).
-
-Switch the driver to rely on the internal controller logic for the
-BCM2711/RPi4.
