[PATCH 00/14] drm/ast: Managed modesetting

[Thomas Zimmermann]

This is the first patchset to convert ast to use managed interfaces. These
patches address modesetting. I expect that there will be at least one more
set of patches for memory management and one for device strcutures.

Patches 1 to 11 tackle HW cursor handling. The overall point is to get
cursor support out of the plane functions and put the code into helpers.
There are quite a few improvements that make cursors easier and faster to
use. Patch 10 converts cursors to managed release.

With cursors out of the way, modesetting initialization is much more
simple. Patches 12 to 14 put all related code next to each other and
switch to managed initialization.

The patchset was tested on AST2100 hardware.

Thomas Zimmermann (14):
  drm/ast: Move cursor functions to ast_cursor.c
  drm/ast: Pass struct ast_private instance to cursor init/fini
    functions
  drm/ast: Move cursor fb pinning and mapping into helper
  drm/ast: Update cursor image and checksum from same function
  drm/ast: Move cursor pageflip into helper
  drm/ast: Replace ast_cursor_move() with ast_cursor_show()
  drm/ast: Don't enable HW cursors twice during atomic update
  drm/ast: Add helper to hide cursor
  drm/ast: Keep cursor HW BOs mapped
  drm/ast: Managed cursor release
  drm/ast: Init cursors before creating modesetting structures
  drm/ast: Replace struct ast_crtc with struct drm_crtc
  drm/ast: Use managed mode-config init
  drm/ast: Initialize mode setting in ast_mode_config_init()
