They have an open source userspace built on top of this interface, and the code looks as good as it was going to get out of tree. - Initial atomic modesetting work The need for an atomic modesetting interface to allow userspace to try and send a complete set of modesetting state to the driver has arisen, and been suffering from neglect this past year. No more, the start of the common code and changes for msm driver to use it are in this tree. Ongoing work to get the userspace ioctl finished and the code clean will probably wait until next kernel. - DisplayID 1.3 and tiled monitor exposed to userspace. Tiled monitor property is now exposed for userspace to make use of. - Rockchip drm driver merged. - imx gpu driver moved out of staging Other stuff: - core: panel - MIPI DSI + new panels. expose suggested x/y properties for virtual GPUs - i915: Initial Skylake (SKL) support gen3/4 reset work start of dri1/ums removal infoframe tracking fixes for lots of things. - nouveau: tegra k1 voltage support GM204 modesetting support GT21x memory reclocking work - radeon: CI dpm fixes GPUVM improvements Initial DPM fan control - rcar-du: HDMI support added removed some support for old boards slave encoder driver for Analog Devices adv7511 - exynos: Exynos4415 SoC support - msm: a4xx gpu support atomic helper conversion - tegra: iommu support universal plane support ganged-mode DSI support - sti: HDMI i2c improvements - vmwgfx: some late fixes. - qxl: use suggested x/y properties" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (969 commits) drm: sti: fix module compilation issue drm/i915: save/restore GMBUS freq across suspend/resume on gen4 drm: sti: correctly cleanup CRTC and planes drm: sti: add HQVDP plane drm: sti: add cursor plane drm: sti: enable auxiliary CRTC drm: sti: fix delay in VTG programming drm: sti: prepare sti_tvout to support auxiliary crtc drm: sti: use drm_crtc_vblank_{on/off} instead of drm_vblank_{on/off} drm: sti: fix hdmi avi infoframe drm: sti: remove event lock while disabling vblank drm: sti: simplify gdp code drm: sti: clear all mixer control drm: sti: remove gpio for HDMI hot plug detection drm: sti: allow to change hdmi ddc i2c adapter drm/doc: Document drm_add_modes_noedid() usage drm/i915: Remove '& 0xffff' from the mask given to WA_REG() drm/i915: Invert the mask and val arguments in wa_add() and WA_REG() drm: Zero out DRM object memory upon cleanup drm/i915/bdw: Fix the write setting up the WIZ hashing mode ...

| * drm/panel: simple: Update Innolux N116BGE timingsDaniel Kurtz2014-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several different models of N116BGE. According to commit 0a2288c06aab ("drm/panel: simple: Add Innolux N116BGE panel support"), the video timings are for the eDP variant. The clock and htotal values added by that patch are out of spec according to the datasheets I have seen for the eDP N116BGE (-EA2 and -EB2). This patch changes the values to the "Typ" values on the datasheet.

| * drm/panel: simple: Add support for Hitachi TX23D38VM0CAALucas Stach2014-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | The Hitachi TX23D38VM0CAA is a 9" WVGA TFT LCD panel and can be supported by the simple-panel driver. This panel is connected via LVDS and uses the data enable signal for timing. Since HSYNC/VSYNC are ignored, the split between sync length and porches is arbitrary, as long as the complete horizontal blanking interval is 256 clocks, and the vertical blanking interval is 45 lines.

This panel is connected via LVDS and uses the data enable signal for timing. Since HSYNC/VSYNC are ignored, the split between sync length and porches is arbitrary, as long as the complete horizontal blanking interval is 160 clocks, and the vertical blanking interval is 24 lines.

| * drm/panel: simple: Add missing .bpc fieldsThierry Reding2014-11-07
| | | | | | | | | | | | | | | | | | | | Various panels were missing the .bpc field which encodes the number of bits per color. Not every display driver relies on this value, but since the panels can be used with any display engine it must be specified so that if a driver knows how to differentiate based on this field it can do so.

The binding documentation is included. This panel is connected via LVDS and uses the data enable signal for timing.

| * drm/panel: simple: Update calls to gpiod_get*()Alexandre Courbot2014-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the new flags argument to calls of (devm_)gpiod_get*() and remove any direction setting code afterwards. Currently both forms (with or without the flags argument) are valid thanks to transitional macros in <linux/gpio/consumer.h>. These macros will be removed once all consumers are updated and the flags argument will become compulsary.

* drm/panel: simple: Remove simple-panel compatibleThierry Reding2014-08-06
| | | | | | | | | | simple-panel is not a valid panel model, so there is no data (video timings, etc.) associated with it. Therefore drivers can't do anything useful with it, so it should not appear in the table of OF matches. Device trees will always need to specify the exact model of the panel.
