The Amlogic Meson GXBB/GXL/GXM SoCs embeds a Synopsys DesignWare HDMI TX Controller with a custom Bridge + PHY around the Controller. This driver makes uses of all the custom PHY plat data callbacks and enables the compatible HDMI modes to be configured as a drm_encoder instance. Acked-by:

The HDMI TX controller support HPD and RXSENSE signaling from the PHY via it's STAT0 PHY interface, but some vendor PHYs can manage these signals independently from the controller, thus these STAT0 handling should be moved to PHY specific operations and become optional. The existing STAT0 HPD and RXSENSE handling code is refactored into a supplementaty set of default PHY operations that are used automatically when the platform glue doesn't provide its own operations.

Switch code to use the newly introduced V4L bus formats IDs instead of custom defines. Also use the V4L encoding defines. Some display pipelines can only provide non-RBG input pixels to the HDMI TX Controller, this patch takes the pixel format from the plat_data if provided. Reviewed-by:

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. That was added manually on top of the spatch changes. Signed-off-by:

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.

The associated backlight device can be configured via DT by providing the phandle to the device. If the backlight device is configured, the driver can manage the backligt along with the panel's power state, iow it can turn on the backlight when the panel is enabled and turn it off when the panel is disabled.

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:

The functions can be used to check a component (by it's of_node) if it is part of the omapdss display or output list. If the component is found, it means that the driver is loaded. 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:

omapdrm now uses dispc_ops instead of direct function calls so we can remove all EXPORT_SYMBOLs from dispc. Most of the functions can also be made static, but a few are used outside dispc.c. Signed-off-by: -

Change omapdrm to get dispc_ops and use that to call the dispc functions instead or direct function calls. The change is very straightforward. The only problem was in omap_crtc_init() which calls pipe2vbl(crtc), and at that point of time the crtc->dev link, which is used to get the dispc_ops, has not been set up yet. This patch makes omap_crtc_init() skip the call to pipe2vbl() and instead calls dispc_ops->mgr_get_vsync_irq() directly. Signed-off-by:
