Jayesh Choudhary authored
Currently, mode_valid is defined only in drm_connector_helper_funcs. When the bridge is attached with the 'DRM_BRIDGE_ATTACH_NO_CONNECTOR' flag, the connector is not initialized, and so is the mode_valid hook under connector helper funcs. It also returns MODE_OK for all modes without actually checking the modes. So move the mode_valid hook to drm_bridge_funcs with proper clock checks for maximum and minimum pixel clock supported by the bridge. Signed-off-by:

The BMC output can be viewed via the BMC's web interface or a similar client. Represent it as virtual encoder and connector. It's attached to the same CRTC as the VGA connector. The connector's status depends on the physical connector's status. The BMC is only connected if the physical connector is not. This is necessary to support userspace clients that can only handle a single output per CRTC. The BMC is a server feature. Add a BMC output for all server chips, but not the desktop models.

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. Acked-by:

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. 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. A grep through mainline for compatible strings used by this driver indicates that it is used by IMX boards. The IMX driver appears to be correctly calling drm_atomic_helper_shutdown() so we can remove the calls.

As talked about in commit d2aacaf0 ("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 1e0465eb ("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. Cc: Robert Chiras <robert.chiras@nxp.com> Acked-by:
