For the I80 interface, the video interrupt pending register(VIDINTCON1) should be handled in fimd_irq_handler() and the video interrupt control register(VIDINTCON0) should be handled in fimd_enable_vblank() and fimd_disable_vblank() like RGB interface. So this patch moves each set / unset routines into proper positions. Signed-off-by:

This function is valid only the SoC has SHADOWCON register and it should be used together with fimd_enable_video_output() to match the ENWIN_F bit in WINCON# and C#_EN_F bit in SHADOWCON. Signed-off-by:

The C#_EN_F in SHADOWCON register is updated per frame. So it should be protected by fimd_shadow_protect_win(). Signed-off-by:

The exynos fimd provides video type selection bits from system register but exynos3 series don't has it, so needs has_vtsel flag and we can distinguish whether set video type selection bits. Signed-off-by:

During system resume from suspend to RAM the Exynos DRM driver forced CRTC mode thus turning display on (DPMS_ON). This lead to runtime resuming of DSI which failed because whole LCD power domain was off and it was not allowed to turn on because of system resume in progress. Forcing mode should not be needed and removing it solves this particular problem. This necessary fix for following scenario reproduced on Exynos DRM: 1. Power domain is off before suspending the system. 2. System is suspended to RAM. 3. Resuming starts. The Exynos DRM driver resume callback is called. 4. The Exynos DRM driver calls drm_helper_resume_force_mode() which turns on the screen by calling exynos_dsi_dpms with DRM_MODE_DPMS_ON. 5. The Exynos DSI driver calls pm_runtime_get. The driver runtime resumes and this should turn LCD power domain on. 6. Unfortunately the domain cannot be turned on because system resume is in progress and genpd->prepared_count is positive. Steps to reproduce: 1. Add runtime PM to Exynos DSI driver. 2. Build Exynos DRM/FB without FRAMEBUFFER_CONSOLE. 3. Enable the connector and screen (e.g. with modeset-vsync). 4. echo 3 > /sys/devices/platform/exynos-drm/graphics/fb0/blank 5. echo mem > /sys/power/state 6. Resume.

The command mode panel should draw image earlier than the display on command execution to prevent showing garbage GRAM screen data. So should set dsi->state as DSIM_STATE_ENABLED between calling exynos_dsi_set_display_enable() and drm_panel_enable() to transmit image data before executing display on command. And moves the display on command execution routine from prepare() to enable() in drm_panel_funcs also. Signed-off-by:

For providing VBLANK information, drm_handle_vblank() should be called properly, but it is blocked by wait_vsync_event condition which is set by manager_ops->wait_for_vblank(). So moves it out from wait_vsync_event routine. Signed-off-by:

The exynos_drm_crtc_dpms() waits until pended page flip queue is empty, calls the drm_vblank_off() then calls manager->ops->dpms() when mode is DRM_MODE_DPMS_OFF. The fimd_dpms() is one of manager->ops->dpms()s and finally calls fimd_window_suspend(). But there is no active window and vblank is already off when it is called. So addtional waiting vblank is not necessary any more. Signed-off-by:

exynos_dsi_display is used by internal Exynos DRM framework for representing pair encoder->connecter. As it should be mapped 1:1 to dsi private context it seems more reasonable to embed it directly in that context. As a result further code simplification will be possible. Moreover it will be possible to handle multiple DSI devices in the system. Signed-off-by:

The patch replaces separate calls to driver (de)registration by loops over the array of drivers. As a result it significantly decreases number of ifdefs. Additionally it moves device registration related ifdefs to header file. Changelog v2: - Rebased. - Consider non kms driver in respect to infinite loop issue. Signed-off-by:

This patch fixes null pointer dereference issue incurred when ipp driver is enabled and Exynos drm driver is closed. Non kms driver should register its own sub driver to setup necessary resources, which is done by load(). So null pointer dereference occurs when ipp driver is enabled and Exynos drm driver is closed because ipp core device is registered after component_master_add_with_match call. This patch makes exynos_drm_device_subdrv_probe() to be called after all non kms drivers are registered. Signed-off-by: -

This patch fixes possible infinite loop issue by postponing registration to non kms drivers after component_master_add_with_match call, which can be incurred in all cases that non kms driver is probed and then component bind is failed This patch should be applied on top of below patches, http://comments.gmane.org/gmane.comp.video.dri.devel/117740 http://www.spinics.net/lists/linux-samsung-soc/msg38624.htmlSigned-off-by:

This patch fixes a null pointer dereference issue incurred by calling g2d_remove when exynos_drm_platform_probe is failed. cmdlist_pool of g2d is allocated when g2d sub driver is probed. So if exynos_drm_platform_probe is failed, the g2d sub driver is not probed and the cmdlist_pool is still NULL. Signed-off-by: -

This patch resolves temporarily infinite loop issue incurred when Exynos drm driver is enabled and multi-platform kernel is used by registering Exynos drm device object only in case of Exynos SoC. So this patch will be replaced with more generic way later. Signed-off-by:

It happens on occasion that developers of generic user-space applications abuse the dumb buffer API to get hold of drm buffers that they can both mmap() and use for GPU acceleration, using the assumptions that dumb buffers and buffers available for GPU are a) The same type and can be aribtrarily type-casted. b) fully coherent. This patch makes the most widely used drivers warn nicely when that happens, the next step will be to fail. v2: Move drmP.h changes to drm_gem.h. Fix Radeon dumb mmap breakage. Signed-off-by:
