Nouveau to register its own backlight interface.

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
v2:
* Switch to using ida for generating unique IDs, as suggested by Ilia Mirkin;
* Allocate backlight name on the stack, as suggested by Ilia Mirkin;
* Move `nouveau_get_backlight_name()` to avoid forward declaration, as
suggested by Ilia Mirkin;
* Fix reference to bug report formatting, as reported by Nick Tenney.
v3:
* Define a macro for the size of the backlight name, to avoid defining
it multiple times;
* Use snprintf in place of sprintf.
v4:
* Do not create similarly named interfaces when reaching the maximum
amount of unique names, but fail instead, as pointed out by Lukas Wunner

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.

host1x command buffer patching requires that the buffer object can be
mapped into kernel address space. However, the recent addition of IOMMU
support did not account for this requirement. Therefore host1x engines
cannot be used if IOMMU is enabled.
This patch implements kmap, kunmap, mmap and munmap functions to host1x
buffer objects.

Currently job pinning is optimized to handle only the first buffer
using a certain host1x_bo object and all subsequent buffers using
the same host1x_bo are considered done.
In most cases this is correct, however, in case the same host1x_bo
is used in multiple gathers inside the same job, we skip also
storing the device address (physical or iova) to this buffer.
This patch reworks the host1x_job_pin() to store the device address
to all gathers.

Memory for the brick clock is allocated by devm_kzalloc(), so there is
no need here to free it explicitly.
The only function that calls tegra_clk_sor_brick_register() is the probe
function and it correctly checks and handles the return value, which, on
failure, will cause devm_ allocated memory to be freed automatically.

The devm_pinctrl_register() function returns an error pointer or a valid
handle. So checking for NULL here is pointless and can never trigger.
Check the returned value with IS_ERR instead and propagate this value as
done in the other functions which call devm_pinctrl_register().

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.

http://git.agner.ch/git/linux-drm-fsl-dcu into drm-next
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).

Add a kernel parameter legancyfb_depth (like the i.MX drm driver)
to control the legancy fbdev depth. Default to the so far hard
coded depth of 24-bit. Currently changing the framebuffer depth
is not possible from user space when using the fbdev emulation
layer... This provides a rudimentary mechanism to change depth
without having to change kernel code.

The separate file fsl_dcu_drm_fbdev.c only initialized fbdev
emulation which is a one-line operation. There is not much more
code on sight which justifies a separate file, hence call the
initialization helper directly from the drv file.

Make sure that all outputs are disabled before unloading the DRM
driver. Otherwise vblank handling is not shut down properly and

Use drm_put_dev to unload the driver before disabling clocks.
Otherwise the driver might read a register during unload which
leads to an external abort.
