[PATCH 0/4] drm/i915: Convert fbdev to DRM client

[Thomas Zimmermann]

Convert i915's fbdev code to struct drm_client. Replaces the current
ad-hoc integration. The conversion includes a number of cleanups.

As with most other driver's fbdev emulation, fbdev in i915 is now
just another DRM client that runs after the DRM device has been
registered. This allows to remove the asynchronous initialization,
hopefully.

Once all drivers' fbdev emulation has been converted to struct drm_client,
we can attempt to add additional in-kernel clients. A DRM-based dmesg
log or a bootsplash are commonly mentioned. DRM can then switch easily
among the existing clients if/when required.

Tested on Intel HD 530 hardware.

Thomas Zimmermann (4):
  drm/i915: Move fbdev functions
  drm/i915: Initialize fbdev DRM client with callback functions
  drm/i915: Implement fbdev client callbacks
  drm/i915: Implement fbdev emulation as in-kernel client
