Merge tag 'drm-misc-next-2018-11-21' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for v4.21, part 2:

UAPI Changes:
- Remove syncobj timeline support from drm.

Cross-subsystem Changes:
- Document canvas provider node in the DT bindings.
- Improve documentation for TPO TPG110 DT bindings.

Core Changes:
- Use explicit state in drm atomic functions.
- Add panel quirk for new GPD Win2 firmware.
- Add DRM_FORMAT_XYUV8888.
- Set the default import/export function in prime to drm_gem_prime_import/export.
- Add a separate drm_gem_object_funcs, to stop relying on dev->driver->*gem* functions.
- Make sure that tinydrm sets the virtual address also on imported buffers.

Driver Changes:
- Support active-low data enable signal in sun4i.
- Fix scaling in vc4.
- Use canvas provider node in meson.
- Remove unused variables in sti and qxl and cirrus.
- Add overlay plane support and primary plane scaling to meson.
- i2c fixes in drm/bridge/sii902x
- Fix mailbox read size in rockchip.
- Spelling fix in panel/s6d16d0.
- Remove unnecessary null check from qxl_bo_unref.
- Remove unused arguments from qxl_bo_pin.
- Fix qxl cursor pinning.
