This is not to try to force a new style; this is my interpretation of
what the most common existing style is.
With hopes I don't need to answer so many questions about style going
forward.
Start a new style section in the i915 document to bolt the register
style guide into.

The motivation behind this new interface is expose at runtime the
creation of new OA configs which can be used as part of the i915 perf
open interface. This will enable the kernel to learn new configs which
may be experimental, or otherwise not part of the core set currently
available through the i915 perf interface.

RST uses underscores at the end of words to create crossreferences and
it will accidentally try to link to tinydrm_ and drm_fb_ targets from
the TODO, which is clearly not the intention in this context.

Unfortuantely the kernel-doc in drm_driver isn't rendered yet, but
that will change as soon as drm_driver is kernel-docified properly.

Sync objects are new toplevel drm object, that contain a
pointer to a fence. This fence can be updated via command
submission ioctls via drivers.
There is also a generic wait obj API modelled on the vulkan
wait API (with code modelled on some amdgpu code).
These objects can be converted to an opaque fd that can be
passes between processes.
v2: rename reference/unreference to put/get (Chris)
fix leaked reference (David Zhou)
drop mutex in favour of cmpxchg (Chris)
v3: cleanups from danvet, rebase on drm_fops rename
check fd_flags is 0 in ioctls.
v4: export find/free, change replace fence to take a
syncobj. In order to support lookup first, replace
later semantics which seem in the end to be cleaner.

This is a modesetting driver for the pl111 CLCD display controller
found on various ARM platforms such as the Versatile Express. The
driver has only been tested on the bcm911360_entphn platform so far,
with PRIME-based buffer sharing between vc4 and clcd.
It reuses the existing devicetree binding, while not using quite as
many of its properties as the fbdev driver does (those are left for
future work).
v2: Nearly complete rewrite by anholt, cutting 2/3 of the code thanks
to DRM core's excellent new helpers.
v3: Don't match pl110 any more, don't attach if we don't have a DRM
panel, use DRM_GEM_CMA_FOPS, update MAINTAINERS, use the simple
display helper, use drm_gem_cma_dumb_create (same as our wrapper).
v4: Change the driver's .name to not clash with fbdev in sysfs, drop
platform alias, drop redundant "drm" in DRM driver name, hook up
.prepare_fb to the CMA helper so that DMA fences should work.
v5: Move register definitions inside the driver directory, fix build
in COMPILE_TEST and !AMBA mode.
v6: Drop TIM2_CLKSEL for now to be consistent with existing DT
bindings, switch back to external register definitions.

Also unify/merge with the existing stuff.
I was a bit torn where to put this, but in the end I decided to put
all the ioctl/sysfs/debugfs stuff into drm-uapi.rst. That means we
have a bit a split with the other uapi related stuff used internally,
like drm_file.[hc], but I think overall this makes more sense.
If it's too confusing we can always add more cross-links to make it
more discoverable. But the auto-sprinkling of links kernel-doc already
does seems sufficient.
Also for prettier docs and more cross-links, switch the internal
defines over to an enum, as usual.
v2: Update kerneldoc fro drm_compat_ioctl too (caught by 0day), plus a
bit more drive-by polish.

This was missed in Tomeu's patch. Also remove the kerneldoc for the
internal function, we don't document that in general.
While at it word-smith the docs slightly for more clarity.

drm-misc-next
Resync with drm-next, I have a patch which currently can't be applied
because drm-misc-next lacked the latest drm/i915 code.

SCDC is a mechanism defined in the HDMI 2.0 specification that allows
the source and sink devices to communicate.
This commit introduces helpers to access the SCDC and provides the
symbolic names for the various registers defined in the specification.
V2: Rebase.
V3: Added R-B from Jose.
V4: Rebase
V5: Addressed review comments from Ville
- Handle the I2c return values in a better way (dp_dual_mode)
- Make the macros for SCDC Major/Minor more readable, by adding
a 'GET' in the macro names

I want to split up a few more things and document some details better
(like how exactly to subclass drm_atomic_state). And maybe also split
up the helpers a bit per-topic, but this should be a ok-ish start for
better atomic overview.
v2: Spelling and clarifications (Eric).
v3: Implement suggestion from Gabriel to fix the graph.
v4: Review from Laurent.

First overview text (if there is any), then headers (since generally
you want to start out with the data structures), then all the other
stuff with functions.
Most of this is pre-shpinx, since with the old docbook only the
overview stuff was pulled in directly. Everything else was put in a
per-section index, so include order didn't really matter.

Well, mostly drm_file.h, and clean up all related things:
- I didnt' figure out the difference between preclose and postclose.
The existing explanation in drm-internals.rst didn't convince me,
since it's also really outdated - we clean up pending DRM events in
the core nowadays. I put a FIXME in for the future.
- Another FIXME is to have a macro for default fops.
- Lots of links all around, main areas are to tie the overview in
drm_file.c more into the callbacks in struct drm_device, and the
other is to link render/primary node code to the right sections in
drm-uapi.rst.
- Also moved the open/close stuff to drm_drv.h from drm-internals.rst,
seems like the better place for that information. Since that section
was rather outdated this amounted to full-on rewrite.
A big missing piece here is some overview graph, but I think better to
wait with that one until drm_device and drm_driver are also fully
documented.

drm_platform_init fumble that 0day and Stephen Rothwell reported.

git://anongit.freedesktop.org/git/drm-intel into drm-next
4 weeks worth of stuff since I was traveling&lazy:
- lspcon improvements (Imre)
- proper atomic state for cdclk handling (Ville)
- gpu reset improvements (Chris)
- lots and lots of polish around fences, requests, waiting and
everything related all over (both gem and modeset code), from Chris
- atomic by default on gen5+ minus byt/bsw (Maarten did the patch to
flip the default, really this is a massive joint team effort)
- moar power domains, now 64bit (Ander)
- big pile of in-kernel unit tests for various gem subsystems (Chris),
including simple mock objects for i915 device and and the ggtt
manager.
- i915_gpu_info in debugfs, for taking a snapshot of the current gpu
state. Same thing as i915_error_state, but useful if the kernel didn't
notice something is stick. From Chris.
- bxt dsi fixes (Umar Shankar)
- bxt w/a updates (Jani)
- no more struct_mutex for gem object unreference (Chris)
- some execlist refactoring (Tvrtko)
- color manager support for glk (Ander)
- improve the power-well sync code to better take over from the
firmware (Imre)
- gem tracepoint polish (Tvrtko)
- lots of glk fixes all around (Ander)
- ctx switch improvements (Chris)
- glk dsi support&fixes (Deepak M)
- dsi fixes for vlv and clanups, lots of them (Hans de Goede)
- switch to i915.ko types in lots of our internal modeset code (Ander)
- byt/bsw atomic wm update code, yay (Ville)
