Daniel Vetter d55f5320c7 drm: Move more framebuffer doc from docbook to kerneldoc
I missed a few paragraphs in the docbook that need to be pulled into
the fbdev vfunc docs.

Danilo Cesar Lemes de Paula f03d8ede7a drm/doc: Convert to markdown
DRM Docbook is now Markdown ready. This means its doc is able to
use markdown text on it.

* Documentation/DocBook/drm.tmpl: Contains a table duplicated from
  drivers/gpu/drm/i915/i915_reg.h. This is not needed anymore

* drivers/gpu/drm/drm_modeset_lock.c: had a code example that used
  to look pretty bad on html. Fixed by using proper code markup.

* drivers/gpu/drm/drm_prime.c: Remove spaces between lines to make
  a proper markup list.

* drivers/gpu/drm/i915/i915_reg.h: Altought pandoc supports tables,
  it doesn't support table cell spanning. But we can use fixed-width
  for those special cases.

* include/drm/drm_vma_manager.h: Another code example that should be
  proper indented with four spaces.

v2 (Daniel): Adjust name to gpu.xml due to rename.

v3 (Daniel):
Split out the actual enabling in the Makefile - this way we can merge
the conversion, while just keeping the enabling in a drm-private tree.

Dave Airlie 870a171814 Merge branch 'exynos-drm-next' of git://git.kernel.org:/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
- Support runtime pm
  . In case of most ARM SoC, each IP has each power domain which should be
    controlled by each IP driver using runtime pm interface. So this patch
    series makes each IP driver to control its own power domain when
    drm dpms is requested.
- Support of_graph based dt binding for DP panel.
  . This patch series adds of_graph based dt binding for DP panel.
    And also it keeps backward compatibility. This includes dt binding
    patch so I got Acked-by from Krzysztof Kozlowski who is a Exynos
    SoC maintainer and from Rob Herring who is a device tree maintainer.

- Cleanup for Exynos DRM IPP enhancement.
  . This patch series is a first step for enhancing existing IPP framework
    which will integrate existing IPP functions with DRM KMS part so that
    these can be transparent to userspace. For other portion of the patch
    series, we will have more times for the review.]

Daniel Vetter f6da8c6e5e drm: document drm_crtc_funcs
And merge any docbook we have into the kerneldoc comments.

Since it's a legacy entry point with only two implementation (one each
in atomic and legacy crtc helpers) I've made the documentation for
set_config fairly sparse - no one should ever need to look at this
again, all the ABI we have is baked into code.

For ->page_flip otoh I kept all the extensive docs from the docbook
and even extended it where it was lacking: Currently we have a pile of
legacy page_flip implemantations, and even for atomic drivers there's
not yet a standard implementation in the helpers. Which means every
driver needs to implement this itself, and precise specs are really
valuable.

Otherwise there's just cursor, which really just boils down to "use at
least universal planes". And gamma tables (where we have a bit a mess
with the fbdev helper gamma hooks).

v2: Spelling fixes (Eric).

v3: Suggestions from Thierry.

Daniel Vetter 092d01dae0 drm: Reorganize helper vtables and their docs
Currently we have 4 helper libraries (probe, crtc, plane & atomic)
that all use the same helper vtables. And that's by necessity since we
don't want to litter the core structs with one ops pointer per helper
library. Also often the reuse the same hooks (like atomic does, to
facilite conversion from existing drivers using crtc and plane
helpers).

Given all that it doesn't make sense to put the docs for these next to
specific helpers. Instead extract them into a new header file and
section in the docbook, and add references to them everywhere.

Unfortunately kernel-doc complains when an include directive doesn't
find anything (and it does by dumping crap into the output file). We
have to remove the now empty includes to avoid that, instead of leaving
them in for future proofing.

v2: More OCD in ordering functions.

v3: Spelling plus collate copyright headers properly.

Since Armada 38x SoC can support IP checksum for jumbo frames only on

rather than for the whole SoC.

This patch enables setting custom TX IP checksum limit by adding new
optional property to the mvneta device tree node. If not used, by
default 1600B is set for "marvell,armada-370-neta" and 9800B for other
strings, which ensures backward compatibility. Binding documentation
is updated accordingly.

Linus Torvalds c64410f3ec ARM: SoC fixes for 4.4-rc
There is a small backlog of at91 patches here, the most significant is
 the addition of some sama5d2 Xplained nodes that were waiting on an MFD include
 file to get merged through another tree. We normally try to sort those out
 before the merge window opens, but the maintainer wasn't aware of that here
 and I decided to merge the changes this time as an exception.
 
 On OMAP a series of audio changes for dra7 missed the merge window but turned
 out to be necessary to fix a boot time imprecise external abort error and to
 get audio working.
 
 The other changes are the usual simple changes, here is a list sorted by
 platform:
 
 at91:
 	removal of a useless defconfig option
 	removal of some legacy DT pieces
 	use of the proper watchdog compatible string
 	update of the MAINTAINERS entries for some Atmel drivers
 drivers/scpi:
 	hide get_scpi_ops in module from built-in code

 	add missing .irq_set_type for i.MX GPC irq_chip.
 	fix the wrong spi-num-chipselects settings for Vybrid DSPI devices.

Pull block layer fixes from Jens Axboe:
 "A round of fixes/updates for the current series.

  This looks a little bigger than it is, but that's mainly because we
  pushed the lightnvm enabled null_blk change out of the merge window so
  it could be updated a bit.  The rest of the volume is also mostly
  lightnvm.  In particular:

   - Lightnvm.  Various fixes, additions, updates from Matias and
     Javier, as well as from Wenwei Tao.

   - NVMe:
        - Fix for potential arithmetic overflow from Keith.
        - Also from Keith, ensure that we reap pending completions from
          a completion queue before deleting it.  Fixes kernel crashes
          when resetting a device with IO pending.
        - Various little lightnvm related tweaks from Matias.

   - Fixup flushes to go through the IO scheduler, for the cases where a
     flush is not required.  Fixes a case in CFQ where we would be
     idling and not see this request, hence not break the idling.  From
     Jan Kara.

   - Use list_{first,prev,next} in elevator.c for cleaner code.  From
     Gelian Tang.

   - Fix for a warning trigger on btrfs and raid on single queue blk-mq
     devices, where we would flush plug callbacks with preemption
     disabled.  From me.

   - A mac partition validation fix from Kees Cook.

   - Two merge fixes from Ming, marked stable.  A third part is adding a
     new warning so we'll notice this quicker in the future, if we screw
     up the accounting.

   - Cleanup of thread name/creation in mtip32xx from Rasmus Villemoes"

Murali Karicheri 17e846aa39 ARM: dts: keystone: k2l: fix kernel crash when clk_ignore_unused is not in bootargs
Currently kernel crash randomly when K2L EVM is booted without
clk_ignore_unused in the bootargs. This workaround is not needed
on other K2 devices such as K2HK and K2E and with this fix, we can
remove the workaround altogether. netcp driver on K2L uses linked
ram on OSR (On chip Static RAM) and requires the clock to this peripheral
enabled for proper functioning. This is the reason for the kernel crash.
So add the clock node to fix this issue.

While at it, remove the workaround documentation as well.

With the fix applied, clk_summary dump shows the clock to OSR enabled.

This is counter-intuitive for a end-user who sets watchdog timeout
value to something like 30s and who expects BMC to reset the system
within 30s of a panic.

This commit allows user to configure the timeout on panic.

Linus Torvalds d83763f4a6 SCSI misc on 20151113
Sorry for the delay in this patch which was mostly caused by getting the
 merger of the mpt2/mpt3sas driver, which was seen as an essential item of
 maintenance work to do before the drivers diverge too much.  Unfortunately,
 this caused a compile failure (detected by linux-next), which then had to be
 fixed up and incubated.  In addition to the mpt2/3sas rework, there are
 updates from pm80xx, lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc
 and ufs plus an assortment of changes including some year 2038 issues, a fix
 for a remove before detach issue in some drivers and a couple of other minor

Linus Torvalds 9aa3d651a9 Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger:
 "This series contains HCH's changes to absorb configfs attribute
  ->show() + ->store() function pointer usage from it's original
  tree-wide consumers, into common configfs code.

  It includes usb-gadget, target w/ drivers, netconsole and ocfs2
  changes to realize the improved simplicity, that now renders the
  original include/target/configfs_macros.h CPP magic for fabric drivers
  and others, unnecessary and obsolete.

  And with common code in place, new configfs attributes can be added
  easier than ever before.

  Note, there are further improvements in-flight from other folks for
  v4.5 code in configfs land, plus number of target fixes for post -rc1
  code"

In the meantime, a new user of the now-removed old configfs API came in
through the char/misc tree in commit 7bd1d4093c ("stm class: Introduce
an abstraction for System Trace Module devices").

This merge resolution comes from Alexander Shishkin, who updated his stm
class tracing abstraction to account for the removal of the old
show_attribute and store_attribute methods in commit 517982229f
("configfs: remove old API") from this pull.  As Alexander says about
that patch:

 "There's no need to keep an extra wrapper structure per item and the
  awkward show_attribute/store_attribute item ops are no longer needed.

  This patch converts policy code to the new api, all the while making
  the code quite a bit smaller and easier on the eyes.

  Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com>"

That patch was folded into the merge so that the tree should be fully
bisectable.
