2014-06-19drm: add register and unregister functions for connectorsThomas Wood
Introduce generic functions to register and unregister connectors. This provides a common place to add and remove associated user space interfaces.

2014-03-24drm/exynos: Split manager/display/subdrvSean Paul
This patch splits display and manager from subdrv. The result is that crtc functions can directly call into manager callbacks and encoder functions can directly call into display callbacks. This will allow us to remove the exynos_drm_hdmi shim and support mixer/hdmi & fimd/dp with common code.

2014-03-24drm/exynos: Remove dpms link between encoder/connectorSean Paul
This patch removes the call from encoder dpms into connector dpms (which will then call back into encoder dpms through the helper function). The callback is likely to keep connector->dpms in the right state when initiating dpms from crtc or encoder, but this isn't the right way to do it. This patch is the first step towards rationalizing power management in the exynos drm driver.

2014-03-24drm/exynos: Pass exynos_drm_manager in manager ops instead of devSean Paul
This patch changes the manager ops callbacks from accepting the subdrv device pointer to taking a pointer to the manager. This will allow us to move closer to decoupling manager/display from subdrv, and subsequently decoupling the crtc/plane from the encoder.

2012-10-31drm/exynos: fix display on issueInki Dae
When crtc_funcs->dpms callback is called, exynos_crtc->dpms and exynos_encoder->dpms are changed to new mode. But if user requests dpms mode operation, OFF -> ON, when crtc's dpms callback is called, exynos_encoder->dpms is also changed to ON. This makes encoder's dpms callback call be ignored so display power couldn't become on again. This patch removes exynos_encoder->dpms changing and adds 'updated' variable to exynos_drm_encoder structure to avoid duplicated overlay updating.

2012-10-04drm/exynos: fix display power call issue.Inki Dae
Changelog v3: make exynos_drm_display_power function use exynos_drm_best_encoder function instead of connector->encoder to get a valid encoder. connector->encoder could be NULL because with DRM_IOCTL_MODE_RMFB request, connector->encoder is NULL so fix this issue. Changelog v2: remove static prefix so that exynos_drm_best_encoder function could be called by other modules. Changelog v1: this patch fixes the issue that display power callback isn't called. with DRM_IOCTL_MODE_RMFB request, encoder->connector becomes NULL so display_ops->power_on() wouldn't be called so this patch makes exynos_drm_best_encoder function to be used to get a valid encoder of each connector.

2012-08-24drm: remove the raw_edid field from struct drm_display_infoJani Nikula
Neither the drm core nor any of the drivers really need the raw_edid field of struct drm_display_info for anything. Instead of being useful, it creates confusion about who is responsible for freeing the memory it points to and setting the field to NULL afterwards, leading to memory leaks and dangling pointers.

Pull drm main changes from Dave Airlie: "This is the main drm pull request, I'm probably going to send two more smaller ones, will explain below. This contains a patch that is also in the fbdev tree, but it should be the same patch, it added an API for hot unplugging framebuffer devices, and I need that API for a new driver. It also contains some changes to the i2c tree which Jean has acked, and one change to moorestown platform stuff in x86. Highlights: - new drivers: UDL driver for USB displaylink devices, kms only, should support correct hotplug operations. - core: i2c speedups + better hotplug support, EDID overriding via firmware interface - allows user to load a firmware for a broken monitor/kvm from userspace, it even has documentation for it. - exynos: new HDMI audio + hdmi 1.4 + virtual output driver - gma500: code cleanup - radeon: cleanups, CS optimisations, streamout support and pageflip fix - nouveau: NVD9 displayport support + more reclocking work - i915: re-enabling GMBUS, finish gpu patch (might help hibernation who knows), missed irq fixes, stencil tiling fixes, interlaced support, aliasesd PPGTT support for SNB/IVB, swizzling for SNB/IVB, semaphore fixes As well as the usual bunch of cleanups and fixes all over the place. I've got two things I'd like to merge a bit later: a) AMD support for all their new radeonhd 7000 series GPU and APUs. AMD dropped this a bit late due to insane internal review processes, (please AMD just follow Intel and let open source guys ship stuff early) however I don't want to penalise people who own this hardware (since its been on sale for 3-4 months and GPU hw doesn't exactly have a lifetime in years) and consign them to using closed drivers for longer than necessary. The changes are well contained and just plug into the driver new gpu functionality so they should be fairly regression proof. I just want to give them a bit of a run on the hw AMD kindly sent me. b) drm prime/dma-buf interface code. This is just infrastructure code to expose the dma-buf stuff to drm drivers and to userspace. I'm not planning on pushing any driver support in this cycle (except maybe exynos), but I'd like to get the infrastructure code in so for the next cycle I can start getting the driver support into the individual drivers. We have started driver support for i915, nouveau and udl along with I think exynos and omap in staging. However this code relies on the dma-buf tree being pulled into your tree first since it needs the latest interfaces from that tree. I'll push to get that tree sent asap. (oh and any warnings you see in i915 are gcc's fault from what anyone can see)."

2011-10-05DRM: add DRM Driver for Samsung SoC EXYNOS4210.Inki Dae
This patch is a DRM Driver for Samsung SoC Exynos4210 and now enables only FIMD yet but we will add HDMI support also in the future. this patch is based on git repository below: git://people.freedesktop.org/~airlied/linux.git branch name: drm-next commit-id: 88ef4e3f4f616462b78a7838eb3ffc3818d30f67 you can refer to our working repository below: http://git.infradead.org/users/kmpark/linux-2.6-samsung branch name: samsung-drm We tried to re-use lowlevel codes of the FIMD driver(s3c-fb.c based on Linux framebuffer) but couldn't so because lowlevel codes of s3c-fb.c are included internally and so FIMD module of this driver has its own lowlevel codes. We used GEM framework for buffer management and DMA APIs(dma_alloc_*) for buffer allocation so we can allocate physically continuous memory for DMA through it and also we could use CMA later if CMA is applied to mainline. Refer to this link for CMA(Continuous Memory Allocator): http://lkml.org/lkml/2011/7/20/45 this driver supports only physically continuous memory(non-iommu).

DRM: code clean and add exception codes. Changelog v3: DRM: Support multiple irq. FIMD and HDMI have their own irq handler but DRM Framework can regiter only one irq handler this patch supports mutiple irq for Samsung SoC. DRM: Consider modularization. each DRM, FIMD could be built as a module. DRM: Have indenpendent crtc object. crtc isn't specific to SoC Platform so this patch gets a crtc to be used as common object. created crtc could be attached to any encoder object. DRM: code clean and add exception codes. Changelog v4: DRM: remove is_defult from samsung_fb. is_default isn't used for default framebuffer. DRM: code refactoring to fimd module. this patch is be considered with multiple display objects and would use its own request_irq() to register a irq handler instead of drm framework's one. DRM: remove find_samsung_drm_gem_object() DRM: move kernel private data structures and definitions to driver folder. samsung_drm.h would contain only public information for userspace ioctl interface. DRM: code refactoring to gem modules. buffer module isn't dependent of gem module anymore. DRM: fixed security issue. DRM: remove encoder porinter from specific connector. samsung connector doesn't need to have generic encoder. DRM: code clean and add exception codes. Changelog v5: DRM: updated fimd(display controller) driver. added various pixel formats, color key and pixel blending features. DRM: removed end_buf_off from samsung_drm_overlay structure. this variable isn't used and end buffer address would be calculated by each sub driver. DRM: use generic function for mmap_offset. replaced samsung_drm_gem_create_mmap_offset() and samsung_drm_free_mmap_offset() with generic ones applied to mainline recentrly. DRM: removed unnecessary codes and added exception codes. DRM: added comments and code clean. Changelog v6: DRM: added default config options. DRM: added padding for 64-bit align.
