The kernel favours 'unsigned int' over plain 'unsigned'. Replace all
occurences of the latter by the former. This avoid lots of checkpatch
complaints in patches that touch lines where a plain 'unsigned' is used.

Rather than trusting the cached value of plane_state->vma->fence to
imply whether the plane_state itself holds a reference on the
framebuffer's fence, use the information provided in the
plane_state->flags (PLANE_HAS_FENCE). Note that we still assume that FBC
is entirely bounded by the plane_state active life span; it's not clear
if that is a safe assumption.

Currently we make the unilateral decision inside
i915_gem_object_pin_to_display() where the VMA should resided (inside
the fence and mappable region or above?). This is not our decision to
make as it impacts on how the display engine can use the resulting
scanout object, and it would rather instruct us where to place the VMA so
that it can enable the features it wants. As such, make the pin flags an
argument to i915_gem_object_pin_to_display() and control them from
intel_pin_and_fence_fb_obj()
Whilst taking control of the mapping for ourselves, start tracking how
we use it to avoid trying to free a fence we never claimed:

i965 and g4x still have the pipe select bits in the plane control
registers, they're just hardcoded to select a specific pipe. However
plane C on i965 can still move between the pipes, thus we should
program the pipe select bits on i965 if we want to expose plane C
some day.
Since there is no harm in programming the bits on any plane on
i965/g4x let's just always set them. This will also make our
pre-computed register value match what the hardware register
would read, should we want to cross check the two.

G4x cursor control registers still allow us to write to the pipe select
bits even though cursors are supposed to be fixed to a specific pipe.
Bspec tells us that we should only ever write 0 to these bits. Let's
follow that recommendation. On ilk+ the bits become hardwired to 0.
Also looks like ICL repurposes these bits for some other use, so
we had better stop setting them to bogus values there.

Add some compile time assrts to the frontbuffer tracking to make sure
that we have enough bits per pipe to cover all the planes, and that we
have enough total bits to cover all the planes across all pipes.
We'll ignore any potential clash between the overlay bit and the
plane bits because that will allow us to keep using a total of 32
bits for the foreseeable future.
While at it change the macros to use BIT() and GENMASK(). The latter
gets rid of the hardcoded 0xff and thus means we can change the
number of bits per pipe by just changing
INTEL_FRONTBUFFER_BITS_PER_PIPE.

Remove tinydrm_of_find_backlight from tinydrm-helpers.c. We now have
a generic of_find_backlight defined in backlight.c. Let the callers
of tinydrm_of_find_backlight call of_find_backlight. Also, remove
select BACKLIGHT_LCD_SUPPORT and select BACKLIGHT_CLASS_DEVICE from
tinydrm/Kconfig as it is a hack that is no longer needed.

A bit boring documentation fix, but gets rid of the warnings:

[Depends on fe7bc493d979 ("scripts: kernel-doc: support in-line comments
on nested structs/unions") in docs-next to actually fix the warnings.]

Move it out of the csv dungeon.
While at it add the missing link to the helper functions for setting
up the "panel rotation" property.
Also OCD how we list enum property values and their corresponding docs.
Going for a nest definition list seams cleanest, no need for also making
it an uordered list.

Just a bit of drive-by OCD. All the other property docs use enumerations,
for some nice visual consistency. It also neatly highlights the property
name.

Motivated by patch review.
The table is really hard to read in source form, hard to edit, and
we've moved away to more focused sections about specific features and
how they're exposed in properties.
Those sections can then more easily enumerate options, link to helper
functions and other parts of the docs. All things that get ugly real
fast in the docs.

During igt, we frequently call into the driver to reset both HW and
driver state (idling the device, waiting for it to become idle and
freeing off old objects) to ensure that we start each test/subtest/pass
from known state. This process incurs an RCU barrier or two to ensure
that any such pending frees are indeed flushed before we return.
However, unconditionally waiting on the RCU barrier adds needless delay
to many callers, which adds up to several seconds when repeated thousands
of times. We can skip the rcu_barrier() if by tracking how many outstanding
frees we have, we know there are none.
The same path is used along suspend, where we may be able to save the
unconditional RCU barrier.
To put it into perspective with a completely meaningless
microbenchmark, igt/gem_sync/idle is improved from 50ms to 30us on bdw.
v2: Remove the extra synchronize_rcu() inside i915_drop_caches_set()

The PL111 needs to filter valid modes based on memory bandwidth.
I guess it is a pretty simple operation, so we can still claim
the DRM KMS helper pipeline is simple after adding this (optional)
vtable callback.
