2024-06-12drm/panel: himax-hx83102: fix incorrect argument to mipi_dsi_msleepTejas Vipin1-3/+3

2024-06-12drm/bridge-connector: implement glue code for HDMI connectorDmitry Baryshkov3-3/+174
In order to let bridge chains implement HDMI connector infrastructure, add necessary glue code to the drm_bridge_connector. In case there is a bridge that sets DRM_BRIDGE_OP_HDMI, drm_bridge_connector will register itself as a HDMI connector and provide proxy drm_connector_hdmi_funcs implementation. Note, to simplify implementation, there can be only one bridge in a chain that sets DRM_BRIDGE_OP_HDMI. Setting more than one is considered an error. This limitation can be lifted later, if the need arises.

2024-06-12drm/bridge-connector: switch to using drmm allocationsDmitry Baryshkov1-18/+5
Turn drm_bridge_connector to using drmm_kzalloc() and drmm_connector_init() and drop the custom destroy function. The drm_connector_unregister() and fwnode_handle_put() are already handled by the drm_connector_cleanup() and so are safe to be dropped.

2024-06-12drm/connector: hdmi: allow disabling Audio InfoframeDmitry Baryshkov2-0/+37
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.

It's the responsibility of a correctly written DRM modeset driver to call drm_atomic_helper_shutdown() at shutdown time and that should be disabling / unpreparing the panel if needed.

2024-06-11drm/panel: raydium-rm67191: Stop tracking enabledDouglas Anderson1-19/+2
As talked about in commit d2aacaf07395 ("drm/panel: Check for already prepared/enabled in drm_panel"), we want to remove needless code from panel drivers that was storing and double-checking the prepared/enabled state. Even if someone was relying on the double-check before, that double-check is now in the core and not needed in individual drivers. The conversion of the rm67191 panel driver follows many of the other panel drivers but has a few differences that need to be called out. Like in commit 1e0465eb16a4 ("drm/panel: otm8009a: Don't double check prepared/enabled"), this panel also uses the "prepared" flag to prevent the backlight functions from running when the panel is powered off. This is probably not the safest thing to do but the old behavior was preserved. See the discussion in the otm8009a patch. Because of this, I've left the driver tracking "prepared" but removed its tracking of "enabled". NOTE: as part of this, transition the panel's direct calls to its disable/unprepare functions in shutdown to call through DRM panel.

As talked about in commit d2aacaf07395 ("drm/panel: Check for already prepared/enabled in drm_panel"), we want to remove needless code from panel drivers that was storing and double-checking the prepared/enabled state. Even if someone was relying on the double-check before, that double-check is now in the core and not needed in individual drivers. NOTE: as part of this, transition the panel's direct calls to its disable function in shutdown/remove to call through DRM panel.

It's the responsibility of a correctly written DRM modeset driver to call drm_atomic_helper_shutdown() at shutdown time and that should be disabling / unpreparing the panel if needed. Panel drivers shouldn't be calling these functions themselves. A recent effort was made to fix as many DRM modeset drivers as possible [1] [2] [3] and most drivers are fixed now.
