[PATCH v4 0/3] drm/vc4: hdmi: Add jack detection to HDMI audio driver

[David Turner <david.turner@raspberrypi.com>]

This series enables jack detection for HDMI audio on vc4 devices.  This
means that userspace audio applications can detect when HDMI devices are
connected or disconnected, for example to play/pause or switch to
another audio device.

Changes in v4:
- Split the update of the comment on
  drm_atomic_helper_connector_hdmi_hotplug() into a separate patch
- Update the wording of the comment
- Add Reviewed-by tags
- Link to v3:
  https://lore.kernel.org/r/20250312-vc4_hotplug-v3-0-d75878677de8@raspberrypi.com

Changes in V3:
- Update comment on drm_atomic_helper_connector_hdmi_hotplug() to
  clarify that it must be called for disconnets too

Changes in V2:
- split initial patch into fix and jack detection feature as
  suggested by Dmitry
