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.

TPO TPG110 Panel
================
This binding builds on the DPI bindings, adding a few properties
as a superset of a DPI. See panel-dpi.txt for the required DPI
bindings.
This panel driver is a component that acts as an intermediary
between an RGB output and a variety of panels. The panel
driver is strapped up in electronics to the desired resolution
and other properties, and has a control interface over 3WIRE
SPI. By talking to the TPG110 over SPI, the strapped properties
can be discovered and the hardware is therefore mostly
self-describing.
+--------+
SPI -> | TPO | -> physical display
RGB -> | TPG110 |
+--------+
If some electrical strap or alternate resolution is desired,
this can be set up by taking software control of the display
over the SPI interface. The interface can also adjust
for properties of the display such as gamma correction and
certain electrical driving levels.
The TPG110 does not know the physical dimensions of the panel
connected, so this needs to be specified in the device tree.
It requires a GPIO line for control of its reset line.
The serial protocol has line names that resemble I2C but the
protocol is not I2C but 3WIRE SPI.
Required properties:
- compatible : "tpo,tpg110"
- compatible : one of:
"ste,nomadik-nhk15-display", "tpo,tpg110"
"tpo,tpg110"
- grestb-gpios : panel reset GPIO
- scen-gpios : serial control enable GPIO
- scl-gpios : serial control clock line GPIO
- sda-gpios : serial control data line GPIO
- width-mm : see display/panel/panel-common.txt
- height-mm : see display/panel/panel-common.txt
The device needs to be a child of an SPI bus, see
spi/spi-bus.txt. The SPI child must set the following
properties:
- spi-3wire
- spi-max-frequency = <3000000>;
as these are characteristics of this device.
Required nodes:
- Video port for DPI input, see panel-dpi.txt
- Panel timing for DPI setup, see panel-dpi.txt
The device node can contain one 'port' child node with one child
'endpoint' node, according to the bindings defined in
media/video-interfaces.txt. This node should describe panel's video bus.

Defaults for .gem_prime_import and export
-----------------------------------------
Most drivers don't need to set drm_driver->gem_prime_import and
->gem_prime_export now that drm_gem_prime_import() and drm_gem_prime_export()
are the default.
struct drm_gem_object_funcs
---------------------------
GEM objects can now have a function table instead of having the callbacks on the
DRM driver struct. This is now the preferred way and drivers can be moved over.
