The DRM-managed function to register a CRTC is
drmm_crtc_alloc_with_planes(), which will allocate the underlying
structure and initialisation the CRTC.
However, we might want to separate the structure creation and the CRTC
initialisation, for example if the structure is shared across multiple
DRM entities, for example an encoder and a connector.
Let's create an helper to only initialise a CRTC that would be passed as
an argument.

Introduce per-plane and per-CRTC scaling filter properties to allow
userspace to select the driver's default scaling filter or
Nearest-neighbor(NN) filter for upscaling operations on CRTC and
plane.
Drivers can set up this property for a plane by calling
drm_plane_create_scaling_filter() and for a CRTC by calling
drm_crtc_create_scaling_filter().
NN filter works by filling in the missing color values in the upscaled
image with that of the coordinate-mapped nearest source pixel value.
NN filter for integer multiple scaling can be particularly useful for
for pixel art games that rely on sharp, blocky images to deliver their
distinctive look.

This patch adds a couple of helpers to remove the boilerplate involved
in grabbing all of the modeset locks.
I've also converted the obvious cases in drm core to use the helpers.
The only remaining instance of drm_modeset_lock_all_ctx() is in
drm_framebuffer. It's complicated by the state clear that occurs on
deadlock. ATM, there's no way to inject code in the deadlock path with
the helpers, so it's unfit for conversion.

- Relocate ret argument to the end of the list (Daniel)

Instead of always re-initializing the variables we need to clean up on
out, move the re-initialization into the branch that goes back to retry
label.
This is a lateral move right now, but will allow us to pull out the
modeset locking into common code. I kept this change separate to make
things easier to review.

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.

drm_mode_setcrtc() retries modesetting in case one of the functions it
calls returns -EDEADLK. connector_set, mode and fb are freed before
retrying, but they are not set to NULL. This can cause
drm_mode_setcrtc() to use those variables.
For example: On the first try __drm_mode_set_config_internal() returns
-EDEADLK. connector_set, mode and fb are freed. Next retry starts, and
drm_modeset_lock_all_ctx() returns -EDEADLK, and we jump to 'out'. The
code will happily try to release all three again.
This leads to crashes of different kinds, depending on the sequence the
EDEADLKs happen.
Fix this by setting the three variables to NULL at the start of the
retry loop.

If the ioctl is not supported on a particular piece of HW/driver
combination, report ENOTSUP (aka EOPNOTSUPP) so that it can be easily
distinguished from both the lack of the ioctl and from a regular invalid
parameter.
v2: Across all the kms ioctls we had a mixture of reporting EINVAL,
ENODEV and a few ENOTSUPP (most where EINVAL) for a failed
drm_core_check_feature(). Update everybody to report ENOTSUPP.
v3: ENOTSUPP is an internal errno! It's value (524) does not correspond
to a POSIX errno, the one we want is ENOTSUP. However,
uapi/asm-generic/errno.h doesn't include ENOTSUP but man errno says
"ENOTSUP and EOPNOTSUPP have the same value on Linux,
but according to POSIX.1 these error values should be
distinct."
so use EOPNOTSUPP as its equivalent.

If the user-space does not support aspect-ratio, and requests for a
modeset with mode having aspect ratio bits set, then the given
user-mode must be rejected. Secondly, while preparing a user-mode from
kernel mode, the aspect-ratio info must not be given, if aspect-ratio
is not supported by the user.
This patch:
1. rejects the modes with aspect-ratio info, during modeset, if the
user does not support aspect ratio.
2. does not load the aspect-ratio info in user-mode structure, if
aspect ratio is not supported.
3. adds helper functions for determining if aspect-ratio is expected
in user-mode and for allowing/disallowing the aspect-ratio, if its
not expected.
