[PATCH 0/7] drm/udl: Convert to simple-pipe helpers and clean up

[Thomas Zimmermann <tzimmermann@suse.de>]

With only a single display pipeline and primary plane, udl is perfect
for simple-pipe helpers. Patches 1 to 3 do the convertion. This enables
atomic modesetting for udl devices.

Patches 4 to 7 clean up handling of color depth and framebuffers. With
universal planes that come with simple pipe, display updates can be
implemented with DRM's damage handlers. The primary plane's formats
array allows to export the correct preferred color depth. The original
value was choosen for maximum compatibility, but did not represent the
device's capability.

The patchset has been tested by running the fb console, X11 and Weston
on a DisplayLink adapter.

Thomas Zimmermann (7):
  drm/udl: Init connector before encoder and CRTC
  drm/udl: Convert to struct drm_simple_display_pipe
  drm/udl: Remove unused encoder and CRTC code
  drm/udl: Set preferred color depth to 16 bpp
  drm/udl: Convert to drm_atomic_helper_dirtyfb()
  drm/udl: Remove struct udl_device.active_fb_16
  drm/udl: Move udl_handle_damage() into udl_modeset.c
