[PATCH RFC v2 0/5] drm/msm: make use of the HDMI connector infrastructure

[Dmitry Baryshkov]

This patchset sits on top Maxime's HDMI connector patchset ([1]).

Currently this is an RFC exploring the interface between HDMI bridges
and HDMI connector code. This has been lightly verified on the Qualcomm
DB820c, which has native HDMI output. If this approach is considered to
be acceptable, I'll finish MSM HDMI bridge conversion (reworking the
Audio Infoframe code). Other bridges can follow the same approach (we
have lt9611 / lt9611uxc / adv7511 on Qualcomm hardware).

Changes in v2:
- Dropped drm_connector_hdmi_setup(). Instead added
  drm_connector_hdmi_init() to be used by drm_bridge_connector.
- Changed the drm_bridge_connector to act as a proxy for the HDMI
  connector  infrastructure. This removes most of the logic from
  the bridge drivers.
- Link to v1: https://lore.kernel.org/r/20240308-bridge-hdmi-connector-v1-0-90b693550260@linaro.org
