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.

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:

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: -

We want to change the dispc API from plain functions to a struct with functions pointers, so that omapdrm can call either omapdss or omapdss6 depending on the platform. This patch adds 'struct dispc_ops' and adds functions to omapdss-base to set and get the ops. Signed-off-by: -

omapdrm still uses a few non-dispc functions: dss_feat_get_num_mgrs(), dss_feat_get_num_ovls() and dss_feat_get_supported_color_modes(). We want to provide omapdrm a single dispc_ops function pointer struct so that omapdrm will use either the current omapdss or the new omapdss6 driver depending on the platform. Those three functions are really dispc functions, but are located in the dss_features.c for legacy reasons. This patch adds similar functionss to the dispc, and changes omapdrm to use those new functions. Underneath the functions still call the functions from dss_feature.c. Signed-off-by: -

display.c uses dsi_get_pixel_size() which is implemented in the DSI driver, and we won't have that in the omapdss-base module, to which we want to move display.c This patch changes display.c not to use dsi_get_pixel_size(). The call can be replaced with a simple check for OMAP_DSS_DSI_FMT_RGB565. We can also make dsi_get_pixel_size() static as it's no longer used outside dsi.c. Signed-off-by: -

We are working towards enabling omapdss6, which will consists of a new dss, dispc and dpi drivers. omapdss6 will be a new module. The panel, encoder and omapdrm will need to use either the current omapdss driver or the new omapdss6 driver, depending on the platform. This will be implemented with a common base module and function pointers. This patch adds a skeleton omapdss-base.ko module, to which we'll be moving common dss functionality like registration of the panels. Signed-off-by: -

While implementing writeback support, odd behavior of WBDELAYCOUNT was observed with the combination of WB capture and HDMI. The result of the debugging was that the HDMI sync polarities are not set correctly. The current code sets the sync polarities going from HDMI WP to DISPC according to the video mode used, which seems to work normally fine, but causes problems with WB as WB expects the syncs to be active-high. This patch changes the HDMI sync polarities so that the DISPC always gets active-high syncs from HDMI WP, and the HDMI core gets sync polarities according to the used video mode. Signed-off-by:

Add support for render nodes in omap driver and allow required ioctls to be accessible via render nodes. This enables unprivileged clients to allocate resources like GEM buffers for rendering their content into. Mode setting (KMS ioctls) is not allowed using render nodes. These buffers are then shared with a previleged process (e.g compositor) that has mode setting access. An example of this use case is Android where the hardware composer is the only master and has mode setting access. Every other client then uses render node(e.g /dev/dri/renderD128 to allocate and use its buffers. Signed-off-by:

The clock source selection for the LCD outputs is too hardcoded at the moment. For example, LCD3 is set to use PLL2_1, and PLL2 doesn't exist on DRA72x SoCs. There are quite many ways to configure the clocks, even using HDMI PLL for LCD outputs, but enabling full configuration of the clocks is rather tricky. This patch improves the situation a bit by checking if the PLL about to be used exists, and if not, tries another one. Signed-off-by:
