Remove the obsolete fb unreferencing system that is no longer used
since we've transitioned to atomic modeset.

Push responsibility for managing the clock during DPMS down into the
variant backend, rather than the CRTC layer having knowledge of its
state.

Rather than writing all bits of SPU_ADV_REG on modeset, only write
what we need to change, and initialise the register in the variant
initialisation.

Move the armada_drm_mode_config_funcs to armada_drv.c, since this now
has less to do with FBs than it does with general mode configuration.
In doing so, we need to make armada_fb_create() visible to armada_drv.c,
which reveals a function name clash with armada_fbdev.c. Rename the
version in armada_fbdev.c.

Remove the unused CRTC colourspace properties - userspace does not make
use of these. In any case, these are not a property of the CRTC, since
they demonstrably only affect the video (overlay) plane, irrespective
of the format of the graphics (primary) plane.

This driver can use drm_fb_helper_lastclose() as its .lastclose callback.
It can also use drm_fb_helper_output_poll_changed() as its
.output_poll_changed callback.

drm_debugfs_cleanup() now removes all minor->debugfs_list entries
automatically, so no need to do this explicitly. Additionally it
uses debugfs_remove_recursive() to clean up the debugfs files,
so no need for adding fake drm_info_node entries.
And finally there's no need to clean up on error,
drm_debugfs_cleanup() is called in the error path.

Now that the drm_connector_register() is gone from tda998x, we can
remove the mid-layer from armada-drm, eliminating the load, unload,
debugfs_init, and debugfs_cleanup callbacks from armada's drm_driver
structure. No functional changes.

Reusing the Big DRM Lock just leaks, and the few things left that
dev->struct_mutex protected are very well contained - it's just the
linear drm_mm manager.
With this armada is completely struct_mutex free!
v2: Convert things properly and also take the lock in
armada_gem_free_object, and remove the stale comment (Russell).

Our vblank event code belongs in armada_crtc.c rather than the core of
the driver. Move it there.

Remove the function armada_drm_vbl_event_remove_unlocked() that is not used anywhere.
This was partially found by using a static code analysis program called cppcheck.

Move the variant pointer into the armada_crtc structure, and update for
the resulting changes.

Move the variant initialisation entirely to the CRTC init function -
the variant support is really about the CRTC properties than the whole
system, and we want to treat each CRTC individually when we support DT.

Call drm_fb_helper_restore_fbdev_mode() upon last close so that in the
event of the X server crashing, we have some kind of mode restored.

This patch adds ARGB hardware cursor support to the DRM driver for the
Marvell Armada SoCs. ARGB cursors are supported at either 32x64 or
64x32 resolutions.

This patch adds support for the pair of LCD controllers on the Marvell
Armada 510 SoCs. This driver supports:
- multiple contiguous scanout buffers for video and graphics
- shm backed cacheable buffer objects for X pixmaps for Vivante GPU
acceleration
- dual lcd0 and lcd1 crt operation
- video overlay on each LCD crt via DRM planes
- page flipping of the main scanout buffers
- DRM prime for buffer export/import
This driver is trivial to extend to other Armada SoCs.
Included in this commit is the core driver with no output support; output
support is platform and encoder driver dependent.
