The omap_dss_device .check_timings() and .set_timings() operations operate on struct videomode, while the DRM API operates on struct drm_display_mode. This forces conversion from to videomode in the callers. While that's not a problem per se, it creates a difference with the drm_bridge API. Replace the videomode parameter to the .check_timings() and .set_timings() operations with a drm_display_mode. This pushed the conversion to videomode down to the DSS devices in some cases. If needed they will be converted to operate on drm_display_mode natively. Signed-off-by:

The encoder .atomic_check() and connector .mode_valid() operations both walk through the dss devices in the pipeline to validate the mode. Factor out the common code in a new omap_drm_connector_mode_fixup() function. Signed-off-by:

The mode setting handler of the VENC stores the video mode internally, to then convert it to a configuration when programming the hardware. The stored mode is otherwise unused. Cache the configuration directly instead. Signed-off-by:

The DISPC timings checks relate to the CRTC, but they're performed in the encoder and connector .atomic_check() and .mode_valid() operations. Move them to the CRTC .mode_valid() operation. Signed-off-by:

The field is only used to check whether the device is connected, and we can do so by checking the dss field instead. Remove the src field. Signed-off-by:

For HDMI pipelines, when the output gets disconnected the device handling CEC needs to be notified. Instead of guessing which device that would be (and sometimes getting it wrong), notify all devices in the pipeline. Signed-off-by:

The source pointer will be removed to the omap_dss_device structure. Store it internally in the DSI panel driver data. Signed-off-by:

Display pipelines based on drm_bridge are handled from the bridge closest to the CRTC. To move to that model we thus need to transition away from walking pipelines in the other direction, and from accessing the device at the end of the pipeline when possible. Remove most accesses to the display device from the omap_connector implementation, and don't store it in the omap_connector structure. - For debug messages we can simply use the connector name instead. - For type checks we can use the drm_connector type. - For operation lookup we can start at the other end of the pipeline and locate the last matching device. The display device is still passed to the connector init function in order to find its type, which requires access to the end of the pipeline. Signed-off-by:

The DT bindings for the OMAP DSS allow assigning numerical IDs to display outputs through display entries in the alias node. The driver uses this information to sort pipelines according to the order specified in DT, making it possible for a system to give a priority order to outputs. Retrieval of the alias ID is done when initializing display dss devices. That code will be removed when moving to drm_bridge and drm_panel. Move retrieval of the alias ID to display pipeline connection time and store it in the pipeline structure instead to keep the feature. Signed-off-by:

The TV encoder supports both PAL and NTSC modes, but when queried for the list of modes it supports, only the currently selected mode is reported. Fix it and report the two modes unconditionally. Signed-off-by:

Instead of manually iterating over the dss devices in the pipeline to find the first one that implements the .get_modes() operation, add a new operation flag for .get_modes() and use the omap_connector_find_device() helper function to locate the right dss device. Signed-off-by:

Now that the .get_modes() operations takes a drm_connector and fills it with modes, it becomes easy to fill display information in the same operation without requiring a separate .get_size() opearation. Signed-off-by:

Laurent Pinchart authored
omap_dss_device operations expose fixed video timings through a .get_timings() operation that return a single timing for the device. To prepare for the move to drm_bridge, modify the API to instead add DRM modes directly to the connector. As this puts more burden on display devices, we also create a helper function for panels to add a single DRM mode from the panel video timings. Signed-off-by:

The omapdrm and omapdss drivers are architectured based on display pipelines made of multiple components handled from sink (display) to source (DSS output). This is incompatible with the DRM bridge and panel APIs that handle components from source to sink. Reconcile the omapdrm and omapdss drivers with the DRM bridge and panel model by reversing the direction of the DSS device .enable() and .disable() operations. This completes the move to the DRM bridge model, with the notable exception of the DSI pipelines that will require more work. We also adapt the omapdss shutdown handler dss_shutdown() to shut down all active pipelines starting from the pipeline output device instead of the display device. As a consequence the for_each_dss_display() macro isn't used and can be removed, and the omapdss_device_get_next() function underlying the macro can be simplified to search for output devices only.

The displays (connectors, panels and encoders) bail out from their .enable() and .disable() handlers if the dss device is already enabled or disabled. Those safety checks are not needed when the functions are called through the omapdss_device_ops, as the .enable() and .disable() handlers are called from the DRM atomic helpers that already guarantee that no double enabling or disabling can occur. However, the handlers are also called directly from the .remove() handler. While this shouldn't be needed either as the modules can't be removed as long as the device is in use, it's still a good practice to disable the device explicitly. There is currently a safety check in .remove() in some drivers but not all of them. Remove the safety checks from the .enable() and .disable() handlers, and add missing ones in the .remove() handler.

Laurent Pinchart authored
The displays (connectors, panels and encoders) return an error from their .enable() handler when the dss device is not connected. They also disconnect the dss device explicitly from their .remove() handler if it is still connected. Those safety checks are not needed: - The .enable() handler is called from code paths that access the dss devices chain from the display device, which is set to NULL when the device isn't connected. - The .remove() handler can only be called when unloading the module as the driver has the suppress_bind_attrs attribute set, and a reference to the module is taken when constructing the dss devices chain, so the module can only be unloaded when the dss device is disconnected. Remove the safety checks. Signed-off-by:

Laurent Pinchart authored
The internal encoders return an error from their .enable() handler when their are not connected to a dss manager. As the flag used is set and cleared in the connect and disconnect handlers, this effectively checks whether the omap_dss_device is connected. The .enable() handler is called from code paths that access the dss devices chain from the display device, which is set to NULL when the device isn't connected, making it impossible to access the device in that case. The safety check is thus not needed, remove it. Signed-off-by:

All .enable() and .disable() handlers for panels and connectors share common code that validates and updates the device's state. Move it to common locations in the omap_encoder_enable() and omap_encoder_disable() handlers. The enabled check in the .disable() handler is left untouched, it will be addressed separately.

Currently, every arch/*/include/uapi/asm/Kbuild explicitly includes the common Kbuild.asm file. Factor out the duplicated include directives to scripts/Makefile.asm-generic so that no architecture would opt out of the mandatory-y mechanism. um is not forced to include mandatory-y since it is a very exceptional case which does not support UAPI.

The generic-y is redundant under the following condition: - arch has its own implementation - the same header is added to generated-y - the same header is added to mandatory-y If a redundant generic-y is found, the warning like follows is displayed: scripts/Makefile.asm-generic:20: redundant generic-y found in arch/arm/include/asm/Kbuild: timex.h I fixed up arch Kbuild files found by this.

During a simple no-op (nothing changed) build I saw 39 invocations of the C compiler with the argument "-print-file-name=include". We don't need to call the C compiler 39 times for this--one time will suffice. Let's change NOSTDINC_FLAGS to a simply expanded variable to avoid this since there doesn't appear to be any reason it should be recursively expanded. On my build this shaved ~400 ms off my "no-op" build. Note that the recursive expansion seems to date back to the (really old) commit e8f5bdb0 ("[PATCH] Makefile include path ordering"). It's a little unclear to me if the point of that patch was to switch the variable to be recursively expanded (which it did) or to avoid directly assigning to NOSTDINC_FLAGS (AKA to switch to +=) because someone else (out of tree?) was setting it. I presume later since if the only goal was to switch to recursive expansion the patch would have just removed the ":". Signed-off-by:
