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)
