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.
