It's not a core function, and the matching atomic functions are also
not in the core. Plus the suspend/resume helper is also already there.
Needs a tiny bit of open-coding, but less midlayer beats that I think.

This patch introduces the 'vrr_enabled' CRTC property to allow
dynamic control over variable refresh rate support for a CRTC.
This property should be treated like a content hint to the driver -
if the hardware or driver is not capable of driving variable refresh
timings then this is not considered an error.
Capability for variable refresh rate support should be determined
by querying the vrr_capable drm connector property.
It is worth noting that while the property is intended for atomic use
it isn't filtered from legacy userspace queries. This allows for Xorg
userspace drivers to implement support.

In some cases CRTCs are active but are not able to generating events, at
least not at every frame at it's expected to.
This is typically the case when the CRTC is feeding a writeback connector
that has no job queued. In this situation the CRTC is usually stopped
until a new job is queued, and this can lead to timeouts when part of
the pipeline is updated but no new jobs are queued to the active
writeback connector.
In order to solve that, we add a ->no_vblank flag to drm_crtc_state
and ask the CRTC drivers to set it to true when they know they're not
able to generate VBLANK events. The core drm_atomic_helper_fake_vblank()
helper can then be used to fake VBLANKs at commit time.

The per-crtc commit_list is kept for places where we have to look

The reason behind the original indirection through the helper
functions was to allow existing drivers to overwrite how they handle
properties. For example when a vendor-specific userspace had
expectations that didn't match atomic. That seemed likely, since
atomic is standardizing a _lot_ more of the behaviour of a kms driver.
But 20 drivers later there's no such need at all. Worse, this forces
all drivers to hook up the default behaviour, breaking userspace if
they forget to do that. And it forces us to export a bunch of core
function just for those helpers.
And finally, these helpers are the last places using
drm_atomic_legacy_backoff() and the implicit acquire_ctx.
This patch here just implements the new behaviour and updates the
docs. Follow-up patches will garbage-collect all the dead code.
v2: Fixup docs even better!
v3: Make it actually work ...
v4: Drop the uses_atomic_modeset() checks from the previous patch
again, since they're now moved up in the callchain.

Atomic helpers really want this instead of the hacked-up legacy
backoff trick, which unfortunately prevents drivers from using their
own private drm_modeset_locks.
Aside: There's a few atomic drivers (nv50, vc4, soon vmwgfx) which
don't yet use the new atomic color mgmt/gamma table stuff. Would be
nice if they could switch over and just hook up
drm_atomic_helper_legacy_gamma_set() instead.

The vblank is mostly CRTC specific and implemented as part of CRTC
driver. Let's keep the vblank hooks struct drm_driver for legacy
drivers, and add corresponding hooks in struct drm_crtc_funcs. These
hooks take struct drm_crtc pointer as argument, and will be called by
core vblank handling code for DRIVER_MODESET drivers.
The new hooks get plugged into core by adding wrapper functions for
vblank handling code. The .get_vblank_counter hook is effectively
optional, as we provide drm_vblank_no_hw_counter() as the default
fallback in the wrapper function.

I've forgotten to remove this when revamping the

sed -e 's/\( \* .*\)struct &\([_a-z]*\)/\1\&struct \2/' -i
Originally I wasnt a friend of this style because I thought a
line-break between the "&struct" and "foo" part would break it. But a
quick test shows that " * &struct \n * foo\n" works pefectly well with
current kernel-doc. So time to mass-apply these changes!

It adds a crtc helper drm_crtc_from_index() to find the registered CRTC
with a given index, just like drm_plane_from_index().

Stop relying on a per crtc_state last_vblank_count, we shouldn't touch
crtc_state after commit. Move it to atomic_state->crtcs.
Also stop re-using new_crtc_state->enable, we can now simply set a
bitmask with crtc_crtc_mask.
Changes since v1:
- Keep last_vblank_count in __drm_crtc_state.

<drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has
now been split into separate files for each object type, but still
includes most other KMS headers to avoid breaking driver compilation.
As a step towards fixing that problem, remove the inclusion of
<drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where
appropriate. Also remove the forward declarations of the drm_encoder and
drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not
needed in the header.
<drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a
forward declaration of struct drm_encoder in order to allow including it
as the first header in a compilation unit.

Create one timeline context for each CRTC to be able to handle out-fences
and signal them. It adds a few members to struct drm_crtc: fence_context,
where we store the context we get from fence_context_alloc(), the
fence seqno and the fence lock, that we pass in fence_init() to be
used by the fence.
v2: Comment by Daniel Stone:
- add BUG_ON() to fence_to_crtc() macro
v3: Comment by Ville Syrjälä
- Use more meaningful name as crtc timeline name
v4: Comments by Brian Starkey
- Use even more meaninful name for the crtc timeline
- add doc for timeline_name
Comment by Daniel Vetter
- use in-line style for comments
- rebase after fence -> dma_fence rename
v5: Comment by Daniel Vetter
- Add doc for drm_crtc_fence_ops
v6: Comment by Chris Wilson
- Move fence_to_crtc to drm_crtc.c
- Move export of drm_crtc_fence_ops to drm_crtc_internal.h
- rebase against latest drm-misc

And also put the overview section into the KMS Properties part of the
docs, instead of randomly-placed within the helpers - this is part of
the uabi.
With this patch I think drm_crtc.[hc] is cleaned up and entirely
documented.

And shuffle the kernel-doc structure a bit since drm_crtc.[hc] now
only contains CRTC-related functions and structures.
v2:
- rebase onto drm-misc
- don't forget to move drm_mode_config_cleanup.
- move 2 internal decls under the right heading (Chris)

The contents of drm_{plane,crtc,connector}_state is dumped before
commit. If a driver extends any of the state structs, it can implement
the corresponding funcs->atomic_print_state() to add it's own driver
specific state.
