Bring rc1 to start the new release dev. Signed-off-by: Maxime Ripard <mripard@kernel.org>
2025-01-07drm/connector: make mode_valid take a const struct drm_display_modeDmitry Baryshkov
The mode_valid() callbacks of drm_encoder, drm_crtc and drm_bridge take a const struct drm_display_mode argument. Change the mode_valid callback of drm_connector to also take a const argument.

2025-01-04drm/display/hdmi: implement hotplug functionsDmitry Baryshkov
The HDMI Connectors need to perform a variety of tasks when the HDMI connector state changes. Such tasks include setting or invalidating CEC address, notifying HDMI codec driver, updating scrambler data, etc. Implementing such tasks in a driver-specific callbacks is error prone. Start implementing the generic helper function (currently handling only the HDMI Codec framework) to be used by drivers utilizing HDMI Connector framework.

2024-12-05drm/display: hdmi: add generic mode_valid helperDmitry Baryshkov
Add drm_hdmi_connector_mode_valid(), generic helper for HDMI connectors. It can be either used directly or as a part of the .mode_valid callback.

If CONFIG_MODVERSIONS is enabled, then using the HDMI Connector framework can result in build failures. Rename the function to make it fit into the name requirements.

2024-06-12drm/connector: hdmi: allow disabling Audio InfoframeDmitry Baryshkov
Add drm_atomic_helper_connector_hdmi_disable_audio_infoframe(), an API to allow the driver disable sending the Audio Infoframe. This is to be used by the drivers if setup of the infoframes is not tightly coupled with the audio functionality and just disabling the audio playback doesn't stop the HDMI hardware from sending the Infoframe.

2024-05-28drm/connector: hdmi: Add Infoframes generationMaxime Ripard
Infoframes in KMS is usually handled by a bunch of low-level helpers that require quite some boilerplate for drivers. This leads to discrepancies with how drivers generate them, and which are actually sent. Now that we have everything needed to generate them in the HDMI connector state, we can generate them in our common logic so that drivers can simply reuse what we precomputed.

2024-05-28drm/connector: hdmi: Create an HDMI sub-stateMaxime Ripard
The next features we will need to share across drivers will need to store some parameters for drivers to use, such as the selected output format. Let's create a new connector sub-state dedicated to HDMI controllers, that will eventually store everything we need.
