Merge tag 'drm-misc-next-2017-11-30' of git://anongit.freedesktop.org/drm/drm-misc into drm-next
Cross-subsystem Changes: - device tree doc for the Mitsubishi AA070MC01 and Tianma TM070RVHG71 panels (Lukasz Majewski) and for a 2nd endpoint on stm32 (Philippe Cornu) Core Changes: The most important changes are: - Add drm_driver .last_close and .output_poll_changed helpers to reduce fbdev emulation footprint in drivers (Noralf) - Fix plane clipping in core and for vmwgfx (Ville) Then we have a bunch of of improvement for print and debug such as the addition of a framebuffer debugfs file. ELD connector, HDMI and improvements. And a bunch of misc improvements, clean ups and style changes and doc updates [airlied: drop eld bits from amdgpu_dm] Driver Changes: - sii8620: filter unsupported modes and add DVI mode support (Maciej Purski) - rockchip: analogix_dp: Remove unnecessary init code (Jeffy Chen) - virtio, cirrus: add fb create_handle support to enable screenshots(Lepton Wu) - virtio: replace reference/unreference with get/put (Aastha Gupta) - vc4, gma500: Convert timers to use timer_setup() (Kees Cook) - vc4: Reject HDMI modes with too high of clocks (Eric) - vc4: Add support for more pixel formats (Dave Stevenson) - stm: dsi: Rename driver name to "stm32-display-dsi" (Philippe Cornu) - stm: ltdc: add a 2nd endpoint (Philippe Cornu) - via: use monotonic time for VIA_WAIT_IRQ (Arnd Bergmann) * tag 'drm-misc-next-2017-11-30' of git://anongit.freedesktop.org/drm/drm-misc: (96 commits) drm/bridge: tc358767: add copyright lines MAINTAINERS: change maintainer for Rockchip drm drivers drm/vblank: Fix vblank timestamp debugs drm/via: use monotonic time for VIA_WAIT_IRQ dma-buf: Fix ifnullfree.cocci warnings drm/printer: Add drm_vprintf() drm/edid: Allow HDMI infoframe without VIC or S3D video/hdmi: Allow "empty" HDMI infoframes dma-buf/fence: Fix lock inversion within dma-fence-array drm/sti: Handle return value of platform_get_irq_byname drm/vc4: Add support for NV21 and NV61. drm/vc4: Use .pixel_order instead of custom .flip_cbcr drm/vc4: Add support for DRM_FORMAT_RGB888 and DRM_FORMAT_BGR888 drm: Move drm_plane_helper_check_state() into drm_atomic_helper.c drm: Check crtc_state->enable rather than crtc->enabled in drm_plane_helper_check_state() drm/vmwgfx: Try to fix plane clipping drm/vmwgfx: Use drm_plane_helper_check_state() drm/vmwgfx: Remove bogus crtc coords vs fb size check gpu: gma500: remove unneeded DRIVER_LICENSE #define drm: don't link DP aux i2c adapter to the hardware device node ...
