version 8:
- move drm_blend.o from drm-y to drm_kms_helper-y to avoid
EXPORT_SYMBOL(drm_atomic_helper_normalize_zpos)
- remove dead function declarations in drm_crtc.h
version 7:
- remove useless EXPORT_SYMBOL()
- better z-order wording in Documentation
version 6:
- add zpos in gpu documentation file
- merge Ville patch about zpos initial value and API improvement.
I have split Ville patch between zpos core and drivers
version 5:
- remove zpos range check and comeback to 0 to N-1
normalization algorithm
version 4:
- make sure that normalized zpos value is stay
in the defined property range and warn user if not
This patch adds support for generic plane's zpos property property with
well-defined semantics:
- added zpos properties to plane and plane state structures
- added helpers for normalizing zpos properties of given set of planes
- well defined semantics: planes are sorted by zpos values and then plane
id value if zpos equals
Normalized zpos values are calculated automatically when generic
muttable zpos property has been initialized. Drivers can simply use
plane_state->normalized_zpos in their atomic_check and/or plane_update
callbacks without any additional calls to DRM core.

Compare to Marek's original patch zpos property is now specific to each
plane and no more to the core.
Normalize function take care of the range of per plane defined range
before set normalized_zpos.

This reverts commit 11c21e73f848844d439cbccb42a1018b8c560e5c.
For reasons totally unclear this manages to wreak havoc with the audio

Instead of scratching heads too much while CI is down, let's revert
before more trouble is caused.

This was somehow lost between v3 and the merged version in Maarten's
patch merged as:
commit f2d580b9a8149735cbc4b59c4a8df60173658140
Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Date: Wed May 4 14:38:26 2016 +0200
drm/core: Do not preserve framebuffer on rmfb, v4.
Actual code copied from Maarten's patch, but with the slight change to
just use dev->mode_config.funcs->atomic_commit to decide whether to
use the atomic path or not.

- Group declarations for separate files (drm_bridge.c, drm_edid.c)
- Move declarations only used within drm.ko to drm_crtc_internal.h
- drm_property_type_valid to drm_crtc.c, its only callsite

Like what has been done for connectors add callbacks on encoder,
crtc and plane to let driver do actions after drm device registration.
Correspondingly, add callbacks called before unregister drm device.
version 2:
add drm_modeset_register_all() and drm_modeset_unregister_all()
to centralize all calls
version 3:
in error case unwind registers in drm_modeset_register_all
fix uninitialed return value
inverse order of unregistration in drm_modeset_unregister_all
version 4:
move function definitions in drm_crtc_internal.h
remove not needed documentation

This changes the code to handle being called multiple times without
side effects. The new names seems more suitable for what it does.

This is just a bit fallout from patch polishing and moving the
get_prop logic fully into the core:
- Drop EXPORT_SYMBOL and make the helpers static.
- Drop kerneldoc since not used by drivers.
- Move the cross-file function declarations only used by drm.ko
internally to an internal header.
v2: keep the gist of the comments, requested by Rob.

Makes more sense and gives better grouping in the DocBook function
reference sections. To make this possible we need to expose two
functions from drm_crtc.c though. To avoid further namespace pollution
in the system wide headers create a new internal header for such drm
internal symbols.
I expect that longer-term we'll add tons more, but since my goal here
is to polish the kerneldoc that's for another day.
