[PATCH v2 00/16] drm/udl: Better modesetting, hot-unplug, protocol

[Thomas Zimmermann]

This patchset reworks the udl driver's modesetting code.

Patches #1 to #5 improve the connector code with various updates.

Patches #6 to #10 improve the modesetting code. Patch #7 replaces the
simple-KMS helpers with the regular atomic helpers. Patch #9 adds DRM
hot-unplugging. The driver had some unplugging support via USB functions,
the DRM side was probably not prepared yet. Patch #10 changes damage
updates to the damage iterator. This minimizes the amount of data to
send over USB.

Patches #11 to #16 add protocol constants for the various UDL display
operations.

Tested with X11, console and Weston.

v2:
	* use FIELD_GET macros when programming scanout address (Javier)
	* improve commit messages (Javier)
	* drop empty atomic_disable plane helper
