This set of changes contains a bunch of cleanups to the host1x driver as
well as the addition of a pin controller for DPAUX, which is required by
boards to configure the DPAUX pads in AUX mode (for DisplayPort) or I2C
mode (for HDMI and DDC).
Included is also a bit of rework of the SOR driver in preparation to add
DisplayPort support as well as some refactoring and cleanup.
Finally, all output drivers are converted to runtime PM, which greatly
simplifies the handling of clocks and resets.

The SOR clock can have various sources, with the most commonly used
being the sor_safe, pll_d2_out0, pll_dp and sor_brick clocks. These
are configured using a three level mux, of which the first 2 levels
can be treated as one. The direct parents of the SOR clock are the
sor_safe, sor_brick and sor_src clocks, whereas the pll_d2_out0 and
pll_dp clocks can be selected as parents of the sor_src clock via a
second mux.
Previous generations of Tegra have only supported eDP and LVDS with
the SOR, where LVDS was never used on publicly available hardware.
Clocking for this only ever required the first level mux (to select
between sor_safe and sor_brick).
Tegra210 has a new revision of the SOR that supports HDMI and hence
needs to support the second level mux to allow selecting pll_d2_out0
as the SOR clock's parent. This second mux is knows as sor_src, and
operating system software needs a reference to it in order to select
the proper parent.

Back-merge tag 'v4.7-rc5' into drm-next
Linux 4.7-rc5
The fsl-dcu pull needs -rc3 so go to -rc5 for now.
On Tegra124, Tegra132 and Tegra210 devices the pads used by the Display
Port Auxiliary (DPAUX) channel are multiplexed such that they can also
be used by one of the internal I2C controllers. Note that this is
different from I2C-over-AUX supported by the DPAUX controller. The
register that configures these pads is part of the DPAUX controllers
register set and so a pinctrl driver is being added for the DPAUX device
to share these pads. Add the device-tree binding documentation for the
DPAUX pad controller.
Although there is only one group of pads associated with the DPAUX that
can be multiplexed, the group still needs to be described by the binding.
If the 'groups' property is not present in the binding, then the pads
will not be allocated by the pinctrl core for a client and this would
allow another client to re-configure the same pads that may already be
in-use.
Please note that although the "off" function for the DPAUX pads is not
technically a pin-mux setting but more of a pin-conf setting it is
simpler to expose these as a function so that the user can simply select
either "aux", "i2c" or "off" as the current function/mode.
Update the main DPAUX binding documentation to reference the DPAUX pad
controller binding document and add the 'i2c-bus' subnode. The 'i2c-bus'
subnode is used for populating I2C slaves for the DPAUX device so that
the I2C driver core does not attempt to add the DPAUX pad controller
nodes as I2C slaves.

Two straightforward fixes. One is a concurrency issue only affecting
SAS connected SATA drives, but which could hang the storage subsystem
if it triggers (because the outstanding command count on error never
goes back to zero) and the other is a NO_TAG fallout from the switch
to hostwide tags which causes the system to crash on module insertion
(we've checked carefully and only the 53c700 family of drivers is
vulnerable to this issue).

We already have a fallback in place to fill out the unique from
dev->unique, which is set to something reasonable in drm_dev_alloc.
Which means we only need to have a special set_busid for pci devices,
to be able to care the backwards compat code for drm 1.1 around, which
libdrm still needs.
While developing and testing this patch things blew up in really
interesting ways, and the code is rather confusing in naming things
between the kernel code, ioctl #defines and libdrm. For the next brave

Pandoc really did a bad job of converting the big KMS properties table
to RST. Instead, put the properties into a separate plain text CSV file,
and include it in the RST file. The generated output isn't very pretty,
but at least the information is there, and it's stored in a format
that's easier to process and improve upon at a later time.
The CSV file was generated by copy-pasting the table from the HTML
generated by the DocBook toolchain into LibreOffice Calc, and then saved
as CSV, unmodified.

While splitting the document up, the headings "shifted" from what pandoc
generated. Use the following order for headings for consistency:
==============
Document title
==============
First
=====
Second
------
Third
~~~~~
Leave the lower level headings as they are; I think those are less
important. Although RST doesn't mandate a specific order ("Rather than
imposing a fixed number and order of section title adornment styles, the
order enforced will be the order as encountered."), having the higher
levels the same overall makes it easier to follow the documents.
[I'm sort of kind of writing the recommendation for docs-next in the
mean time, but this order seems sensible, and is what I'm proposing.]

This is the first step towards converting the DocBook gpu.tmpl to Sphinx
and reStructuredText, the new kernel documentation tool and markup.
Use Jon's "cheesy conversion script" in Documentation/sphinx/tmplcvt to
do the rough conversion. Do the manual edits in follow-up patches. Add a
new Documentation/gpu directories for the graphics related
documentation. (Hooray, now we can have directories based on topics
rather than tools under Documentation.)
We also won't remove the DocBook gpu.tmpl yet so it's easier to build
both and compare the results for parity.

Jani Nikula says:
Jon, this is v2 of [1] and [2], with a considerable amount of polish and
fixes added. We started dogfooding this within drm-intel, and Daniel has
reviewed the lot and contributed a number of fixes, most notably
accurate file and line number references from Sphinx build
errors/warnings to the kernel-doc comments in source code.
We believe this is now in good shape for merging for v4.8. It's all in
my sphinx-for-docs-next branch that you've already looked at; pull
details below.
When this lands in docs-next and we can backmerge to drm, we'll plunge
ahead and convert gpu.tmpl to rst, and have that ready for v4.8. We
think it's best to contribute that via the drm tree, as it'll involve
splitting up the documentation and likely numerous updates to kernel-doc
comments.
I plan to update Documentation/kernel-doc-nano-HOWTO.txt for Sphinx and
rst, obviously converting it to rst while at it.
sas_ata_strategy_handler() adds the works of the ata error handler to
system_unbound_wq. This workqueue asynchronously runs work items, so the
ata error handler will be performed concurrently on different CPUs. In
this case, ->host_failed will be decreased simultaneously in
scsi_eh_finish_cmd() on different CPUs, and become abnormal.
It will lead to permanently inequality between ->host_failed and
->host_busy, and scsi error handler thread won't start running. IO
errors after that won't be handled.
Since all scmds must have been handled in the strategy handler, just
remove the decrement in scsi_eh_finish_cmd() and zero ->host_busy after
the strategy handler to fix this race.
