* drm/layerscape: Add Freescale DCU DRM driverJianwei Wang2015-08-2015-0/+1439
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch add support for Two Dimensional Animation and Compositing Engine (2D-ACE) on the Freescale SoCs. 2D-ACE is a Freescale display controller. 2D-ACE describes the functionality of the module extremely well its name is a value that cannot be used as a token in programming languages. Instead the valid token "DCU" is used to tag the register names and function names. The Display Controller Unit (DCU) module is a system master that fetches graphics stored in internal or external memory and displays them on a TFT LCD panel. A wide range of panel sizes is supported and the timing of the interface signals is highly configurable. Graphics are read directly from memory and then blended in real-time, which allows for dynamic content creation with minimal CPU intervention. The features: (1) Full RGB888 output to TFT LCD panel. (2) Blending of each pixel using up to 4 source layers dependent on size of panel. (3) Each graphic layer can be placed with one pixel resolution in either axis. (4) Each graphic layer support RGB565 and RGB888 direct colors without alpha channel and BGRA8888 BGRA4444 ARGB1555 direct colors with an alpha channel and YUV422 format. (5) Each graphic layer support alpha blending with 8-bit resolution. This is a simplified version, only one primary plane, one framebuffer, one crtc, one connector and one encoder for TFT LCD panel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes two issues. One, when a surface is a proxy for a DMA buffer, it holds an extra reference that needs to be cleared. Two, when fbdev is enabled, we need to unpin the framebuffer before unloading the driver. This is done by a call to vmw_fb_off(). v2 Moved unreferencing surface to from vmw_framebuffer_surface_destroy() to vmw_kms_new_framebuffer() Added "struct vmw_framebuffer *vfb = NULL;" to silence a compiler warning.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For a Screen Target capable display device, the display topology is limited by SVGA_REG_MAX_PRIMARY_BOUNDING_BOX_MEM. Two values are checked against this limit: 1. Size of the bounding box enclosing all the displays, and 2. Size of the total number of displays, e.g. framebuffers The limitations above mean we do not have exact max width and height for the topology.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With screen targets the old legacy display system fbdev doesn't work satisfactory anymore. At best the resolution is severely restricted. Therefore implement fbdev on top of the kms system. With this change, fbdev will be using whatever KMS backend is chosen. There are helpers available for this, so in the future we'd probably want to implement the helper callbacks instead of calling into our KMS implementation directly. v2: Make sure we take the mode_config mutex around modesetting, Also clear the initial framebuffer using vzalloc instead of vmalloc.

To accomplish this, remove the fb surface mutex and list which isn't used anymore, anyway. Finally, make the pin() and unpin() pin the framebuffer for all display system backends, so that fbdev can pin its framebuffer before mapping it. v2: Address review comments: - Fix vmw_framebuffer_unpin() to handle also the surface framebuffer case. - Fix vmw_kms_new_framebuffer() to actually use the only_2d parameter.

| * | drm/panel: Add Samsung prefix to panel driversThierry Reding2015-08-136-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The likelihood of getting a large number of panel drivers from different vendors is quite high. Add a prefix to the two existing Samsung panel drivers to set a guideline for future patch submissions. Using vendor prefixes consistently should allow a cleaner organization of the tree.

| * | drm/exynos: Remove PTN3460 dependencyThierry Reding2015-08-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the PTN3460 driver has been rewritten as a proper I2C driver and there is infrastructure to hook up the bridge with a DRM device, it is no longer necessary to have this dependency to ensure the correct build mode.

Also this finally restores DPMS with atomic mode-setting, something that has been broken since the conversion and which I had originally expected to take far less longer to fix. * tag 'drm/tegra/for-4.3-rc1' of git://anongit.freedesktop.org/tegra/linux: (41 commits) drm/tegra: sor: Add HDMI support drm/tegra: sor: Add Tegra210 eDP support drm/tegra: dc: Implement atomic DPMS drm/tegra: sor: Restore DPMS drm/tegra: dsi: Restore DPMS drm/tegra: hdmi: Restore DPMS drm/tegra: rgb: Restore DPMS drm/tegra: sor: Use DRM debugfs infrastructure for CRC drm/tegra: sor: Write correct head state registers drm/tegra: sor: Constify display mode drm/tegra: sor: Reset the correct debugfs fields drm/tegra: sor: Set minor after debugfs initialization drm/tegra: sor: Provide error messages in probe drm/tegra: sor: Rename registers for consistency drm/tegra: dpaux: Disable interrupt when detached drm/tegra: dpaux: Configure pads as I2C by default drm/tegra: dpaux: Provide error message in probe drm/tegra: dsi: Add Tegra210 support drm/tegra: dsi: Add Tegra132 support drm/tegra: dsi: Add Tegra124 support ...
