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 ;-)

Userspace should set the first 4 bits of drm_radeon_cs_reloc::flags to
a number from 0 to 15. The higher the number, the higher the priority,
which means a buffer with a higher number will be validated sooner.
The old behavior is preserved: Buffers used for write are prioritized over
read-only buffers if the userspace doesn't set the number.

The statistics are:
- VRAM usage in bytes

The last one is actually a counter, so you need to sample it before and after
command submission and take the difference.
This is useful for finding performance bottlenecks. Userspace queries are
also added.

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
info packets, not reading registers in older chips documented as write
only (despite appearing to be read/write in later chips). Others are
code cleanups (using definitions rather than constants where we have
them already in the kernel).
Additional functionality is also added by way of optional support for
the IRQ from the TDA998x, which allows us to avoid busy-waiting for
the EDID reads.

The function reads the link status (6 bytes starting at offset 0x202)
from the DPCD so that it can be conveniently passed to other DPCD
helpers.

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.

This reverts commit d8a5dc3033.
This breaks plymouth installs, either because plymouth is using the file
"incorrectly" or because the patch is incorrect. Either way, this needs
to be reverted until it is all figured out.

This fixes bug introduced in 667a6b7a (regulator: max14577: Add missing
of_node_put). The DTS parsing function returned number of matched
regulators as success status which then was compared against 0 in probe.
Result was a probe fail after successful parsing the DTS:
max14577-regulator: probe of max14577-regulator failed with error 2

This branch contains a bug fix for the way devicetree code identifies
the type of device. Device drivers can contain a list of of_device_ids,
but it more than one entry will match, then the device driver may choose
the wrong one. Commit 105353145e, "match each node compatible against
all given matches first", was queued for v3.14 but ended up causing
other bugs. Commit 06b29e76a7 attempted to fix it but it had other bugs.
Merely reverting the fix and waiting until v3.15 isn't a good option
because there is code in v3.14 that depends on the revised behaviour to
boot.
This branch should finally fixes the problem correctly. This time
instead of just hoping that the patch is correct, this branch also adds
new testcases that validate the behaviour.
The changes in this branch are larger than I would like for a -rc pull,
but moving the test case data out of out of arch/arm so that it could be
validated on other architectures was important.

Enabling SPARSE_IRQ shows up a bug in the irq-orion bridge interrupt
handler. The bridge interrupt is implemented using a single generic
chip. Thus the parameter passed to irq_get_domain_generic_chip()
should always be zero.

ENDPTFLUSH and ENDPTPRIME registers are set by software and clear
by hardware. There is a bit for each endpoint. When we are setting
a bit for an endpoint we should make sure we do not touch other
endpoint bit. There is a race condition if the hardware clear the
bit between the read and the write in hw_write.

The change (008fa749e0) that moved the
node release code to a separate function broke death notifications in
some cases. When it encountered a reference without a death
notification request, it would skip looking at the remaining
references, and therefore fail to send death notifications for them.
