kerneldoc polish will follow in the next patch.
Hopefully documenting the lru scan support a bit better spurs someone
to give this a shot in the ttm eviction code. At least in i915 it
helped quite a lot with memory thrashing on platforms where eviction
was (we've fixed that too meanwhile) fairly expensive.

For giant hilarity the DocBook reference overview is only generated
when in a level 2 section, not in a level 3 section. So we need to
move this up a bit as a side-by-side section to the main PRIME
documentation.
Whatever.
To have a complete set of references add the missing kerneldoc for all
functions exported to modules with the exception of the file private
init/destroy functions - drivers have no business calling those, so
let's just drop the EXPORT_SYMBOL instead.
Also reflow the function parameters to align correctly and break at 80
chars - my OCD couldn't stand them while writing the kerneldoc ;-)

PRIME fds aren't actually GEM fds but are (like the modeset API)
independent of the underlying buffer manager, as long as that one uses
uint32_t as handles. So move that entire section out of the GEM
section and reword it a bit to clarify which parts of PRIME are
generic, and which are the mandatory pieces for GEM drivers to
correctly implement the GEM lifetime rules. The rewording mostly
consists of not mixing up GEM, PRIME and DRM.
I've considered adding some blurbs to the GEM object lifetime section
about interactions with dma-bufs, but then dropped that. As long as
drivers use the right helpers they should have this all implemented
correctly and hence can be regarded as an implementation detail of the
PRIME/GEM helpers. So no need to confuse driver writers with those
tricky interactions.

- This is _not_ a generic interface to create gem objects, but just an
interface to make early boot services (like boot splash) with a
generic KMS userspace driver possible. Hence it's better to move
the documentation for this from the GEM section to the KMS section,
next to the creation of framebuffer objects.
- Make it really clear that the returned handle isn't necessarily a
GEM object (it can also be e.g. a TTM handle when running on top of
vmwgfx).
- Add a paragraph to make it clear that this is just for unaccelarated
userspace - gpu drivers need to have their own buffer object
creation ioctl which is hardware specific.
v2: Clarify that the documentation doesn't just apply to GEM-based
drivers only but is now generally valid, as suggested by David.
v3: Polish the intro sentence a bit and one s/objects/handles/ for
clarification, both suggested by Laurent.

Now that Christian fixed the performance problems with
the feedback buffer in mesa, we can enable variable UVD
clocks. There are multiple UVD power states associated
with different types and numbers of streams. This uses
the appropriate state based on that information rather
than always using the fastest UVD clocks which saves some
power. One possible downside is that this may adversely
affect decode benchmarks since these power states target
specific playback requirements rather than maximum
performance. If that becomes an issue, we can add a
sysfs attribute to force the max UVD state.

Updates from Jean-Fracois for the TDA998x driver, which are on top of
the fixes you have previously pulled, except these changes aren't
intended for -rc, but the next merge window.
Several of these are issues of correctness - passing more correct HDMI

Additional functionality is also added by way of optional support for

This is a superset of the current i2c_dp_aux bus functionality and can
be used to transfer native AUX in addition to I2C-over-AUX messages.
Helpers are provided to read and write the DPCD, either blockwise or
byte-wise. Many of the existing helpers for DisplayPort take a copy of a
portion of the DPCD and operate on that, without a way to write data
back to the DPCD (e.g. for configuration of the link).
Subsequent patches will build upon this infrastructure to provide common
functionality in a generic way.
