9fda81e00e drm/udl: Convert to struct drm_simple_display_pipe 
Udl has a single display pipeline with a primary plane; perfect for
simple-pipe helpers. Convert it over. The old encoder and CRTC code
becomes unused and obsolete.

Exported formats for the primary plane are RGB565 and XRGB8888, with
the latter being emulated. The 16-bit format is the default and what
is used when communicating with the device.

This patch enables atomic modesetting for udl devices.

v3:
	* remove unused field crtc from struct udl_device
	* set crtc_state->no_vblank at beginning of enable()
v2:
	* move suspend/resume changes into separate patch
	* remove non-atomic code

ebfdd6d5e8 drm/udl: add support to export a handle to a FD on UDL. 
Only importing an FD to a handle is currently supported on UDL,
but the exporting functionality is equally useful.

5320918b9a drm/udl: initial UDL driver (v4) 
This is an initial drm/kms driver for the displaylink devices.

Supports fb_defio,
supports KMS dumb interface
supports 24bpp via conversion to 16bpp, hw can do this better.
supports hot unplug using new drm core features.

On an unplug, it disables connector polling, unplugs connectors
from sysfs, unplugs fbdev layer (using Kay's API), drops all the
USB device URBs, and call the drm core to unplug the device.

This driver is based in large parts on udlfb.c so I've licensed
it under GPLv2.
