This adds a new callback to crtc, encoder and bridge helper functions
called mode_valid(). This callback shall be implemented if the
corresponding component has some sort of restriction in the modes
that can be displayed. A NULL callback implicates that the component
can display all the modes.
We also change the documentation so that the new and old callbacks
are correctly documented.
Only the callbacks were implemented to simplify review process,
following patches will make use of them.
Changes in v2 from Daniel:
- Update the warning about how modes aren't filtered in atomic_check -
the heleprs help out a lot more now.
- Consistenly roll out that warning, crtc/encoder's atomic_check
missed it.
- Sprinkle more links all over the place, so it's easier to see where
this stuff is used and how the differen hooks are related.
- Note that ->mode_valid is optional everywhere.
- Explain why the connector's mode_valid is special and does _not_ get
called in atomic_check.
v3: Document what can and cannot be checked in mode_valid a bit better
(Andrjez). Answer: Only allowed to look at the mode, nothing else.

Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ defines to the UAPI
as a convenience.
Ideally the DRM_ROTATE_ and DRM_REFLECT_ property ids are looked up
through the atomic API, but realizing that userspace is likely to take
shortcuts and assume that the enum values are what is sent over the
wire.
As a result these defines are provided purely as a convenience to
userspace applications.
Changes since v3:
- Switched away from past tense in comments
- Add define name change to previously mis-spelled DRM_REFLECT_X comment
- Improved the comment for the DRM_MODE_REFLECT_<axis> comment
Changes since v2:
- Changed define prefix from DRM_MODE_PROP_ to DRM_MODE_
- Fix compilation errors
- Changed comment formatting
- Deduplicated comment lines
- Clarified DRM_MODE_PROP_REFLECT_ comment
Changes since v1:
- Moved defines from drm.h to drm_mode.h
- Changed define prefix from DRM_ to DRM_MODE_PROP_
- Updated uses of the defines to the new prefix
- Removed include from drm_rect.c
- Stopped using the BIT() macro

drm_[cm]alloc* has grown their own kvmalloc with vmalloc fallback
implementations. MM has grown kvmalloc* helpers in the meantime. Let's
use those because it a) reduces the code and b) MM has a better idea
how to implement fallbacks (e.g. do not vmalloc before kmalloc is tried
with __GFP_NORETRY).
drm_calloc_large needs to get __GFP_ZERO explicitly but it is the same
thing as kvmalloc_array in principle.

Include <drm/*.h> instead of relative path from include/drm, then
remove the -Iinclude/drm compiler flag.

For the C file, include <drm/*.h> instead of relative path from
include/drm.
For headers in include/drm/ttm, simplify the <tty/*.h> with "*.h".
This allows us to remove the -Iinclude/drm compiler flag from
drivers/gpu/drm/ttm/Makefile (and from other drivers' Makefiles).

-ENOSYS and -EINVAL are referenced in some static inline functions.
of_drm_find_pane() takes a pointer to struct device_node.
Make this header self-contained to not depend on specific include
order.
