Unlike the connector type, the encoder type is unused by userspace. As it is equally unused in the driver, except in a single location where the connector type can be used instead, hardcode it to DRM_MODE_ENCODER_NONE. This allow removing all code that tries to determine (unsuccessfully in case a bridge is used) the encoder type. Signed-off-by: -

On Gen3 platforms planes are managed by the external VSP compositor on behalf of DRM/KMS. If VSP compositor support is not enabled in the DU driver, the VSP initialization stub routine is called. Return an error from that stub to fail explicitly, otherwise the device won't be usable and the driver will crash. Signed-off-by:

The driver currently handles vblank events only when updating planes on a CRTC. The atomic update API however allows requesting an event when disabling a CRTC. This currently leads to event objects being leaked in the kernel and to events not being sent out. Fix it. Signed-off-by: -

The flags indicate whether data is transmitted LSB to MSB or MSB to LSB on the bus. The exact meaning is bus-type dependent. For instance, for LVDS buses the flags indicate whether the seven data bits transmitted in a clock pulse are sent in normal order (MSB to LSB, slots 0 to 6) or reverse order (LSB to MSB, slots 6 to 0).

omapdrm changes for 4.12 Main changes include: * Add support for render nodes. * Refactor omapdss code to allow multiple DISPC implementations. This is pre-work for DSS6 support. * Fix replication logic bug, which caused RGB565 fb to be shown too dark on a 24bit display. * Improve detection of display stack readiness, which should remove the probe order issues. * Link panel-dpi with its backlight, so that they are turned on/off in sync. * Fix possibly incorrect setup of sync and data-enable signals. * Get rid of DRM_OMAP_NUM_CRTCS config option. * tag 'omapdrm-4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux: (34 commits) drm/omap: Major omap_modeset_init() cleanup drm/omap: Remove the obsolete #define omap_plane _omap_plane hack drm/omap: Fix one ugly indentation style break left by coccinelle drm/omap: Rename enum omap_plane to enum omap_plane_id drm/omap: Get rid of DRM_OMAP_NUM_CRTCS config option drm/omap: fix crash on module unload drm/omap: use drm_atomic_helper_shutdown() drm/omap: fix display SYNC/DE flags drm/omap: dispc: improve debug print of display flags drm/omap: displays: panel-dpi: Support for handling backlight devices drm/omap: poll only connectors where the connect/disconnect can be checked drm/omap: display: Add displays in sorted order to the panel_list drm/omap: Use omapdss_stack_is_ready() to check that the display stack is up drm/omap: dss: Support for detecting display stack readiness drm/omap: dss: Functions to check components in the display/output list drm/omap: fix replication logic drm/omap: remove unused dispc_wb_enable & dispc_wb_is_enabled drm/omap: remove all EXPORT_SYMBOLs from dispc.c drm/omap: use dispc_ops drm/omap: fill dispc_ops ...

Cleanup overly complex omap_modeset_init(). The function is trying to support many unusual configuration, that have never been tested and are not supported by other parts of the dirver. After cleanup the init function creates exactly one connector, encoder, crtc, and primary plane per each connected dss-device. Each connector->encoder->crtc chain is expected to be separate and each crtc is connect to a single dss-channel. If the configuration does not match the expectations or exceeds the available resources, the configuration is rejected. Signed-off-by:

The enum omap_plane conflicted with the same struct name for omapdrm plane private data. This rename should solve the conflict. The rename was implement with this very simple coccinelle patch: ------------------------ @@ @@ enum -omap_plane +omap_plane_id ------------------------ The patch was applied like this: spatch --sp-file <cocci_file> --all-includes --in-place --dir drivers/gpu/drm/omapdrm The above patch did not rename the actual enum definition.

Allocate one CRTC for each connected output and get rid of DRM_OMAP_NUM_CRTCS config option. We still can not create more CRTCs than we have DSS display managers. We also reserve one overlay per CRTC for primary plane so we can not have more CRTCs than we have overlays either. Signed-off-by:

When unloading omapdrm we get a NULL pointer deref in omap_drm_irq_uninstall(). This is caused by: 967dd484 ("drm: remove drm_vblank_no_hw_counter assignment from driver code") We shut down all the crtcs at unload time before calling omap_drm_irq_uninstall, so the code in omap_drm_irq_uninstall() is unnecessary and can be removed.

At the moment VSYNC/HSYNC/DE high/low flags set by the panel/encoder drivers get lost when the videotimings are translated to DRM's videomode, as DRM's mode does not have corresponding flags. DRM has bus-flags for this purpose, and while it lacks a few flags at the moment, it should be used here. However, until we rewrite omapdrm's device model, using bus-flags is rather difficult. As a short term fix, this patch makes sure that every time the videomode is set in omap_crtc_mode_set_nofb(), the driver asks for the SYNC/DE flags from the panel/encoder drivers, and thus we get the correct flags into use.

Instead of 'guessing' based on aliases of the status of the DSS drivers, use the new interface to check that all needed drivers are loaded. In this way we can be sure that all needed drivers are loaded so it is safe to continue the probing of omapdrm. This method will allow the omapdrm to be probed 'headless', without outputs.

When omapdss is loaded (all core components are in place) create a list of devices used in the display graph. This list later can be used by omapdrm via the omapdss_stack_is_ready() function to check that these components are loaded. Based on this information, omapdrm can defer probe in case when the omapdss stack is not ready yet. Signed-off-by:

DSS uses "replication logic" to convert color components from smaller bit widths to bigger bit widths. Without replication logic, the color component would be shifted and the least significant bits would be left at 0, whereas with replication logic, the least significat bits will be filled with the most significant bit. For some reason omapdrm leaves replication logic always to off, which, in the most common case, means that showing 16-bit RGB colors on 24-bit display gives a bit darker colors than expected. The reset value of the replication logic bit is enabled, and it should always be set, as there's no practical reason to disable it. This patch removes the option to disable it from omapdrm, and always sets it to enabled in dispc. Signed-off-by:
