5d156a9c3d drm/bridge: Pass down connector to drm bridge detect hook 
In some application scenarios, we hope to get the corresponding
connector when the bridge's detect hook is invoked.

In most cases, we can get the connector by drm_atomic_get_connector_for_encoder
if the encoder attached to the bridge is enabled, however there will
still be some scenarios where the detect hook of the bridge is called
but the corresponding encoder has not been enabled yet. For instance,
this occurs when the device is hot plug in for the first time.

Since the call to bridge's detect is initiated by the connector, passing
down the corresponding connector directly will make things simpler.

1bd1562d35 drm/bridge-connector: Sync supported_formats with computed ycbcr_420_allowed 
The case of having an HDMI bridge in the pipeline which advertises
YUV420 capability via its ->supported_formats and a non-HDMI one that
didn't enable ->ycbcr_420_allowed, is incorrectly handled because
supported_formats is passed as is to the helper initializing the HDMI
connector.

Ensure HDMI_COLORSPACE_YUV420 is removed from the bitmask passed to
drmm_connector_hdmi_init() when connector's ->ycbcr_420_allowed flag
ends up not being set.

Extend drm_bridge_connector code to read the EDID and use it to update

0beba3f9d3 drm/bridge: connector: add support for HDMI codec framework 
Add necessary glue code to be able to use new HDMI codec framework from
the DRM bridge drivers. The drm_bridge implements a limited set of the
hdmi_codec_ops interface, with the functions accepting both
drm_connector and drm_bridge instead of just a generic void pointer.

This framework is integrated with the DRM HDMI Connector framework, but
can also be used for DisplayPort connectors.

drm/bridge-connector: reset the HDMI connector state 
On HDMI connectors which use drm_bridge_connector and DRM_BRIDGE_OP_HDMI
IGT chokes on the max_bpc property in several kms_properties tests due
to the drm_bridge_connector failing to reset HDMI-related
properties.

Call __drm_atomic_helper_connector_hdmi_reset() if the
drm_bridge_connector has bridge_hdmi.

It is impossible to call this function from HDMI bridges, none of the
bridge callbacks correspond to the drm_connector_funcs::reset().
