drm/tegra: Changes for v4.13-rc1
This starts off with the addition of more documentation for the host1x
and DRM drivers and finishes with a slew of fixes and enhancements for
the staging IOCTLs as a result of the awesome work done by Dmitry and
Erik on the grate reverse-engineering effort.* tag 'drm/tegra/for-4.13-rc1' of git://anongit.freedesktop.org/tegra/linux:
gpu: host1x: At first try a non-blocking allocation for the gather copy

gpu: host1x: Forbid unrelated SETCLASS opcode in the firewall
gpu: host1x: Forbid RESTART opcode in the firewall

gpu: host1x: Do not leak BO's phys address to userspace
gpu: host1x: Correct host1x_job_pin() error handling
gpu: host1x: Initialize firewall class to the job's one
drm/tegra: dc: Disable plane if it is invisible
drm/tegra: dc: Apply clipping to the plane
drm/tegra: dc: Avoid reset asserts on Tegra20

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.Signed-off-by: Tom Cooksey

This commit adds a TODO list to the GPU driver developer's guide. The
content was taken from the DRMJanitors page on the X.Org wiki:https://www.x.org/wiki/DRMJanitors/
The goal is to track a list of refactorings that would be nice to see
merged eventually. Sometimes these would be encountered during patch
review on the mailing list, and at other times one can come across
these while working in a specific area of code.Signed-off-by: Thierry Reding

Move the documentation into Documentation/gpu, link it up and pull in
the kernel doc.No actual text changes except that I did polish the kerneldoc a bit,
especially for vga_client_register().v2: Remove some rst from vga-switcheroo.rst that I don't understand,
but which seems to be the reason why the new vgaarbiter.rst sometimes
drops out of the sidebar index.v3: Drop one level of headings and clarify the vgaarb one a bit.
v4: Fix some typos (Sean).

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.Signed-off-by: Jani Nikula
