So it looks like the code is trying to pick between the passed in fb and
crtc->primary->fb based on that funky 'bool atomic'. But later it will
mix uses of both drm_fb (which was picked by the aforementioned logic)
and crtc->primary->fb. So looks like a bug to me. Let's make it use
drm_fb only.

It's deprecated and only should be used by drivers which still use
drm_platform_init, not by anyone else.
And indeed it's entirely unused and can be nuked.
This required a bit more fudging, but I guess kirin_dc_ops really
wants to operate on the platform_device, not something else. Also
bonus points for implementing abstraction, and then storing the vfunc
in a global variable.
v2: Don't break the build soooo badly :(
Note that the cleanup function is a bit confused: ade_data was never
set as drvdata, and calling drm_crtc_cleanup directly is a bug - this
is called indirectly through drm_mode_config_cleanup, which calls into
crtc->destroy, which already has the call to drm_crtc_cleanup. Which
means we can just nuke it.
Note this is the 2nd attempt after the first one failed and had to be
reverted again in

With the last round of changes all ioctls called by modern drivers now
have their own locking. Everything else is only allowed for legacy
drivers and hence the lack of locking doesn't matter.
One exception is nouveau, due to the DRIVER_KMS_LEGACY_CONTEXT flag.
But that only works its magic on the context and bufs ioctls. And
drm_bufs.c is protected with dev->struct_mutex, and drm_context.c by
the same and dev->ctxlist_mutex. That should be all safe, and we can
finally mandata drm-bkl-less ioctls for everyone!

It only updates per-file feature flags. And all the ioctl which change
behaviour depending upon these flags (they're all kms features) do
_not_ hold the BKL. Therefor this is pure cargo-cult and can be
removed.
Note that there's a risk that the ioctl will behave inconsistently
when userspace is racing with itself, but that's ok. The only thing
it's not allowed to do is oops the kernel, and from an audit all
places are safe.

Currently, every backlight interface created by Nouveau uses the same name,
nv_backlight. This leads to a sysfs warning as it tries to create an already
existing folder. This patch adds a incremented number to the name, but keeps
the initial name as nv_backlight, to avoid possibly breaking userspace; the
second interface will be named nv_backlight1, and so on.
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=86539

* Move `nouveau_get_backlight_name()` to avoid forward declaration, as
suggested by Ilia Mirkin;

TTM was changed a while back to allow for pipelining of buffer moves, and
part of this was the removal of waiting for a BO to idle before calling
move(), placing the responsibility on the driver to do this if required.
That's all well and good, except, we make use of move_notify() to handle
mapping/unmapping from the GPU VMM as move() isn't called on all paths.
This commit adds a wait before unmapping from a VMM in move_notify(), to
prevent GPU page faults where a buffer is still being accessed.

This has been on the TODO list for a while now, recovering from things
such as attempting to execute a push buffer or touch a semaphore in an
unmapped memory area.
The only thing required on the HW side here is that the offending
channel is removed from the runlist, and *not* a full reset of PFIFO.
This used to be a bit messier to handle before the rework to make use
of engine topology info, but is apparently now trivial.

Looping twice when we can do it once is silly. Also use a consistent

We thought that no userspace is using them, but oops libdrm is using
them to figure out whether a driver supports modesetting. Check out
drmCheckModesettingSupported but maybe don't because it's horrible and
totally runs counter to where we want to go with libdrm device
handling. The function looks in the device hierarchy for whether
controlD* exist using the following format string:
/sys/bus/pci/devices/%04x:%02x:%02x.%d/drm/controlD%d
The "/drm" subdirectory is the glue directory from the sysfs class
stuff, and the only way to get at it seems to through
kdev->kobj.parent (when kdev is represents e.g. the card0 chardev
instance in sysfs). Git grep says we're not the only ones touching
that, so I hope it's ok we dig into such internals - I couldn't find a
proper interface for getting at the glue directory.
Quick git grep shows that at least -amdgpu, -ati are using this.
-modesetting do not, and on -intel it's only about the 4th fallback
path for device lookup, which is why this didn't blow up earlier.
Oh well, we need to keep it working, and the simplest way is to add a
symlink at the right place in sysfs from controlD* to card*.
v2:
- Fix error path handling by adding if (!minor) return checks (David)
- Fix the controlD* numbers to match what's been there (David)
- Add a comment what exactly userspace minimally needs.
- Correct the analysis for -intel (Chris).

vc4 already has a proper load sequence, but the unload one needed some
fixups: First unregister, and last drop the final ref.

Some generic TV connector properties are exposed in drm_mode_config, but
they are currently handled independently in each DRM encoder driver.
Extend the drm_connector_state to store TV related states, and modify the
drm_atomic_connector_{set,get}_property() helpers to fill the connector
state accordingly.
Each driver is then responsible for checking and applying the new config
in its ->atomic_mode_{check,set}() operations.

PV_CONTROL_CLK_SELECT_VEC is actually 2 and not 0. Fix the definition and
rework the vc4_set_crtc_possible_masks() to cover the full range of the
PV_CONTROL_CLK_SELECT field.

Some fixes and cleanup, mainly around fbdev emulation. It also adds a
new module parameter which allows to specify the color depth/bpp for
the fbdev emulation (like the IMX DRM driver).
* tag 'drm-fsl-dcu-for-next' of http://git.agner.ch/git/linux-drm-fsl-dcu:
drm/fsl-dcu: introduce kernel parameter to specify fbdev depth
drm/fsl-dcu: remove separate compilation unit for fbdev emulation
drm/fsl-dcu: Propagate the real error code
drm/fsl-dcu: Remove unneeded NULL check
drm/fsl-dcu: disable outputs before unloading driver
drm/fsl-dcu: unload driver before disabling clocks
Another pile of misc stuff, final one for 4.10. If there's some serious
bugfix still I'll send you a pull for drm-misc-next-fixes (like we do with
intel), otherwise this is it and next pull next year for 4.11.
Most interesting bits are probably Chris' fb helper fixes against mst
hotplug oopses.

For CZ, some function pointers like display_configuration_changed
are not set. So when HW manager tries to configure display, we
end up with messages like
"[ powerplay ] this function not implement!"
in the logs. This message is informational, but lacks details
on which function is not implemented and why.
Rather than using KERN_INFO to print the message everytime the
system boots, we rather use pr_debug so that it is only printed
when debug prints are enabled at runtime.
