Linus Torvalds bae41e45b7 sound updates for 3.19-rc1
This became a fairly large pull request.  In addition to the usual
 driver updates / fixes, there have been a high amount of cleanups in
 ASoC area, as well as control API helpers and kernel documentations
 fixes touching through the whole tree.
 
 In the driver side, the biggest changes are the support for new Intel
 SoC found on new x86 machines, and the updates of FireWire dice and
 oxfw drivers.
 
 Some remarkable items are below:
 
 * ALSA core
  - PCM mmap code cleanup, removal of arch-dependent codes
  - PCM xrun injection support
  - PCM hwptr tracepoint support
  - Refactoring of snd_pcm_action(), simplification of PCM locking
  - Robustified sequecner auto-load functionality
  - New control API helpers and lots of cleanups along with them
  - Lots of kerneldoc fixes and cleanups
 
 * USB-audio
  - The mixer resume code was largely rewritten, and the devices with
    quirks are resumed properly.
  - New hardware support: Focusrite Scarlett, Digidesign Mbox1,
    Denon/Marantz DACs, Zoom R16/24
 
 * FireWire
  - DICE driver updates with better duplex and sync support, including
    MIDI support
  - New OXFW driver for Oxford Semiconductor FW970/971 chipset,
    including the previous LaCie Speakers device.  Fullduplex and MIDI
    support included as well as DICE driver.
 
 * HD-audio
  - Refactoring the driver-caps quirk handling in snd-hda-intel
  - More consistent control names representing the topology better
  - Fixups: HP mute LED with ALC268 codec, Ideapad S210 built-in mic
    fix, ASUS Z99He laptop EAPD
 
 * ASoC
  - Conversion of AC'97 drivers to use regmap, bringing us closer to
    the removal of the ASoC level I/O code
  - Clean up a lot of old drivers that were open coding things that
    have subsequently been implemented in the core
  - Some DAPM performance improvements
  - Removal of the now seldom used CODEC mutex
  - Lots of updates for the newer Intel SoC support, including support
    for the DSP and some Cherrytrail and Braswell machine drivers
  - Support for Samsung boards using rt5631 as the CODEC
  - Removal of the obsolete AFEB9260 machine driver
  - Driver support for the TI TS3A227E headset driver used in some
    Chrombeooks
 
 * Others
  - ASIHPI driver update and cleanups
  - Lots of dev_*() printk conversions
  - Lots of trivial cleanups for the codes spotted by Coccinelle

Dave Airlie ca5a71de48 drm: Sanitize DRM_IOCTL_MODE_CREATE_DUMB input
Some drivers erroneously treat the .pitch and .size fields of struct
 drm_mode_create_dumb as inputs. While the include/uapi/drm/drm_mode.h
 header has a comment denoting them as outputs, that seemingly wasn't
 enough to make drivers use them properly.
 
 The result is that some userspace doesn't explicitly zero out those
 fields, assuming that the kernel won't use them. That causes problems
 since the data within the structure might be uninitialized, so bogus
 data may end up confusing drivers (ridiculously large values for the
 pitch, ...).
 
 This series attempts to improve the situation by fixing all drivers to
 not use the output fields. Furthermore to spare new drivers this bad
 surprise, the DRM core now zeros out these fields prior to handing the
 data structure to the driver.
 
 Lessons learned from this are that future IOCTLs should be properly
 documented (in the DRM DocBook for example) and should be rigorously
 defined. To prevent misuse like this, userspace should be required to
 zero out all output fields. The kernel should check for this and fail
 if that's not the case.

Dave Airlie 122387a53e Merge tag 'topic/atomic-helpers-2014-11-09' of git://anongit.freedesktop.org/drm-intel into drm-next
So here's my atomic series, finally all debugged&reviewed. Sean Paul has
done a full detailed pass over it all, and a lot of other people have
commented and provided feedback on some parts. Rob Clark also converted
msm over the w/e and seems happy. The only small thing is that Rob wants
to export the wait_for_vblank, which imo makes sense. Since there's other
stuff still to do I think we should apply Rob's patch (once it has grown
appropriate kerneldoc) later on top of this.

This is just the core<->driver interface plus a big pile of helpers. Short
recap of the main ideas:

- There are essentially three helper libraries in this patch set:

  * Transitional helpers to use the new plane callbacks for legacy plane
    updates and in the crtc helper's ->mode_set callback. These helpers are
    only temporarily used to convert drivers to atomic, but they allow a
    nice separation between changing the driver backend and switching to
    the atomic commit logic.

  * Legacy helpers to implement all the legacy driver entry points
    (page_flip, set_config, plane vfuncs) on top of the new atomic driver
    interface. These are completely driver agnostic. The reason for having
    the legacy support as helpers is that drivers can switch step-by-step.
    And they could e.g. even keep the legacy page_flip code around for some
    old platforms where converting to full-blown atomic isn't worth it.

  * Atomic helpers which implement the various new ->atomic_* driver
    interfaces in terms of the revised crtc helper and new plane helper
    hooks.

- The revised crtc helper implemenation essentially implements all the
  lessons learned in the i915 modeset rework (when using the atomic helpers
  only):

  * Enable/disable sequence for a given config are always the same and
    callbacks are always called in the same order. This contrast starkly
    with the crtc helpers, where the sequence of operations is heavily
    dependent on the previous config.

    One corollary of this is that if the configuration of a crtc only
    partially changes (e.g. a connector moves in a cloned config) the
    helper code will still disable/enable the full display pipeline. This
    is the only way to ensure that the enable/disable sequence is always
    the same.

  * It won't call disable or enable hooks more than once any more because
    it lost track of state, thanks to the atomic state tracking. And if
    drivers implement the ->reset hook properly (by either resetting the hw
    or reading out the hw state into the atomic structures) this even
    extends to the hardware state. So no more disable-me-harder kind of
    nonsense.

  * The only thing missing is the hw state readout/cross-check support, but
    if drivers have hw state readout support in their ->reset handlers it's
    simple to extend that to cross-check the hw state.

  * The crtc->mode_set callback is gone and its replacement only sets crtc
    timings and no longer updates the primary plane state. This way we can
    finally implement primary planes properly.

- The new plane helpers should be suitable enough for pretty much
  everything, and a perfect fit for hardware with GO bits. Even if they
  don't fit the atomic helper library is rather flexible and exports all
  the functions for the individual steps to drivers. So drivers can pick
  what matches and implement their own magic for everything else.

- A big difference compared to all previous atomic series is that this one
  doesn't implement async commit in a generic way. Imo driver requirements
  for that are too diverse to create anything reasonable sane which would
  actually work on a reasonable amount of different drivers. Also, we've
  never had a helper library for page_flips even, so it's really hard to
  know what might work and what's stupid without a bit of experience in the form
  of a few driver implementations.

  I think with the current flexibility for drivers to pick individual
  stages and existing helpers like drm_flip_queue it's rather easy though
  to implement proper async commit.

- There's a few other differences of minor importance to earlier atomic
  series:

  * Common/generic properties are parsed in the callers/core and not in
    drivers, and passed to drivers by directly setting the right members in
    atomic state structures. That greatly simplifies all the transitional
    and legacy helpers an removes a lot of boilerplate code.

  * There's no crazy trylock mode used for the async commit since these
    helpers don't do async commit. A simple ordered flip queue of atomic
    state updates should be sufficient for preventing concurrent hw access
    anyway, as long as synchronous updates stall correctly with e.g.
    flush_work_queue or similar function. Abusing locks to enforce ordering
    isn't a good idea imo anyway.

  * These helpers reuse the existing ->mode_fixup hooks in the atomic_check
    callback. Which means that drivers need to adapat and move a lot less code
    into their atomic_check callbacks.

Now this isn't everything needed in the drm core and helpers for full
atomic support. But it's enough to start with converting drivers, and
except for actually testing multiplane and multicrtc updates also enough to
implement full atomic updates. Still missing are:

- Per-plane locking. Since these helpers here encapsulate the locking
  completely this should be fairly easy to implement.

- fbdev support for atomic_check/commit, so that multi-pipe finally works
  sanely in fbcon.

- Adding and decoding shared/core properties. That just needs to be rebased
  from Rob's latest patch series, with minor adjustments so that the
  decoding happens in the core instead of in drivers.

- Actually adding the atomic ioctl. Again just rebasing Rob's latest patch
  should be all that's needed.

- Resolving how to deal with DPMS in atomic. Atomic is a good excuse to fix up
  the crazy semantics dpms currently has. I'm floating an RFC about this topic
  already.

- Finally I couldn't test connector/encoder stealing properly since my test
  vehicle here doesn't allow a connector on different crtcs. So drivers
  which support this might see some surprises in that area. There is no semantic
  change though in how encoder stealing and assignment works (or at least no
  intended one), so I think the risk is minimal.

As just mentioned I've done a fake conversion of an existing driver using
crtc helpers to debug the helper code and validate the smooth transition
approach. And that smooth transition was the really big motivation for
this. It seems to actually work and consists of 3 phases:

Phase 1: Rework driver backend for crtc/plane helpers

The requirement here is that universal plane support is already implement. If
universal plane support isn't implement yet it might be better though to just do
it as part of this phase, directly using the new plane helpers. There are two
big things to do:

- Split up the existing ->update/disable_plane hooks into check/commit
  hooks and extract the crtc-wide prep/flush parts (like setting/clearing
  GO bits).

- The other big change is to split the crtc->mode_set hook into the plane
  update (done using the plane helpers) and the crtc setup in a new
  ->mode_set_nofb hook.

When phase 1 is complete the driver implements all the new callbacks which
push the software state into hardware, but still using all the legacy entry
points and crtc helpers. The transitional helpers serve as impendance
mismatch here.

Phase 2: Rework state handling

This consists of rolling out the state handling helpers for planes, crtcs
and connectors and reviewing all ->mode_fixup and similar hooks to make
sure they don't depend upon implicit global state which might change in the
atomic world. Any such code must be moved into ->atomic_check functions which
just rely on the free-standing atomic state update structures.

This phase also adds a few small pieces of fixup code to make sure the
atomic state doesn't get out of sync in the legacy driver callbacks.

Phase 3: Roll out atomic support

Now it's just about replacing vfuncs with the ones provided by the helper
and filling out the small missing pieces (like atomic_check logic or async
commit support needed for page_flips). Due to the prep work in phase 1 no
changes to the driver backend functions should be required, and because of
the prep work in phase 2 atomic implementations can be rolled out
step-by-step. So if async commit ins't implemented yet page_flip can be
implemented with the legacy functions without wreaking havoc in the other
operations.

Daniel Vetter cc4ceb484b drm: Global atomic state handling
Some differences compared to Rob's patches again:
- Dropped the committed and checked booleans. Checking will be
  internally enforced by always calling ->atomic_check before
  ->atomic_commit. And async handling needs to be solved differently
  because the current scheme completely side-steps ww mutex deadlock
  avoidance (and so either reinvents a new deadlock avoidance wheel or
  like the current code just deadlocks).

- State for connectors needed to be added, since now they have a
  full-blown drm_connector_state (so that drivers have something to
  attach their own stuff to).

- Refcounting is gone. I plane to solve async updates differently,
  since the lock-passing scheme doesn't cut it (since it abuses ww
  mutexes). Essentially what we need for async is a simple ownership
  transfer from the caller to the driver. That doesn't need full-blown
  refcounting.

- The acquire ctx is a pointer. Real atomic callers should have that
  on their stack, legacy entry points need to put the right one
  (obtained by drm_modeset_legacy_acuire_ctx) in there.

- I've dropped all hooks except check/commit. All the begin/end
  handling is done by core functions and is the same.

- commit/check are just thin wrappers that ensure that ->check is
  always called.

- To help out with locking in the legacy implementations I've added a
  helper to just grab all locks in the backoff case.

v2: Add notices that check/commit can fail with EDEADLK.

v3:
- More consistent naming for state_alloc.
- Add state_clear which is needed for backoff and retry.

v4: Planes/connectors can switch between crtcs, and we need to be
careful that we grab the state (and locks) for both the old and new
crtc. Improve the interface functions to ensure this.

v5: Add functions to grab affected connectors for a crtc and to recompute
the crtc->enable state. This is useful for both helper and atomic ioctl
code when e.g. removing a connector.

v6: Squash in fixup from Fengguang to use ERR_CAST.

v7: Add debug output.

v8: Make checkpatch happy about kcalloc argument ordering.

v9: Improve kerneldoc in drm_crtc.h

v10:
- Fix another kcalloc argument misorder I've missed.
- More polish for kerneldoc.

v11: Clarify the ownership rules for the state object. The new rule is
that a successful drm_atomic_commit (whether synchronous or asnyc)
always inherits the state and is responsible for the clean-up. That
way async and sync ->commit functions are more similar.

v12: A few bugfixes:
- Assign state->state pointers correctly when grabbing state objects -
  we need to link them up with the global state.
- Handle a NULL crtc in set_crtc_for_plane to simplify code flow a bit
  for the callers of this function.

v13: Review from Sean:
- kerneldoc spelling fixes
- Don't overallocate states->planes.
- Handle NULL crtc in set_crtc_for_connector.

v14: Sprinkle __must_check over all functions which do wait/wound
locking to make sure callers don't forget this. Since I have ;-)

v15: Be more explicit in the kerneldoc when functions can return
-EDEADLK what to do. And that every other -errno is fatal.

v16: Indent with tabs instead of space, spotted by Ander.

v17: Review from Thierry, small kerneldoc and other naming polish.

Simon Farnsworth 9fd1f310a1 [media] DocBook media: Clarify V4L2_FIELD_ANY for drivers
Documentation for enum v4l2_field did not make it clear that V4L2_FIELD_ANY
is only acceptable as input to the kernel, not as a response from the
driver.

Make it clear, to stop userspace developers like me assuming it can be
returned by the driver.

Linus Torvalds 4f080f05e6 Merge tag 'docs-for-linus' of git://git.lwn.net/linux-2.6
Pull documentation fixes from Jonathan Corbet:
 "So this is my first pull request since I rashly agreed to look after
  the documentation subtree.  It contains some typo fixes, a few minor
  documentation improvements, and, most importantly, fixes for a couple
  of build problems in various bits of sample code.

  I fully intend to start sending pull requests with signed tags.
  However, due to poor planning on my part and the general obnoxiousness
  of life, I'm 2000 miles away from my private key which is sitting on a
  powered-down machine.  This should be fixed before my next request.

  Meanwhile git.lwn.net is a machine under my control, the patches are
  all trivial, and all have done time in linux-next"

Pull drm updates from Dave Airlie:
 "This is the main git pull for the drm,

  I pretty much froze major pulls at -rc5/6 time, and haven't had much
  fallout, so will probably continue doing that.

Linus Torvalds a2ce35273c sound updates for 3.18-rc1
This time it's a relatively calm update batch, but the amount isn't
 too small in the end.  Here we go over some highlights:
 
 - ALSA core
   - One major change is the support of nonatomic PCM operations.
     This allows the trigger and other callbacks to call schedule(),
     which would be useful for mailbox type communications.  Already
     some drivers (Digigram ones) have been converted to use together
     with threaded irqs as an example.
   - Improvement / fixes of DSD PCM format support
 
 - HD-audio
   - Large volume of rewrites are found in Realtek codec driver for
     converting Dell and HP quirks to generic forms.
   - Inverted dmic code cleanup from David.
   - Realtek COEF access has been optimized.
   - Now HD-audio jack infrastructure allows multiple callbacks, which
     fixes / simplifies the jack-dependent power controls on STAC/IDT
     and VIA codecs.
   - Many additional device-specific fixups as usual
   - A few deadcode cleanups, CA0132 code cleanup, etc.
 
 - ASoC
   - More componentization work from Lars-Peter, this time mainly
     cleaning up the suspend and bias level transition callbacks.
   - Real system support for the Intel drivers and a bunch of fixes
     and enhancements for the associated CODEC drivers, this is going
     to need a lot quirks over time due to the lack of any firmware
     description of the boards.
   - Jack detect support for simple card from Dylan Reid.
   - A bunch of small fixes and enhancements for the Freescale
     drivers.
   - New drivers for Analog Devices SSM4567, Cirrus Logic CS35L32,
     Everest Semiconductor ES8328 and Freescale cards using the ASRC
     in newer i.MX processors.
   - A few simple-card fixes, mostly cleanups but also a fix for
   - interaction between GPIO 0 and simple-card.
 
 - Misc
   - Virtuoso / Oxygen updates by Clemens
   - USB-audio: Yamaha MOTIF XF MIDI port name fixes
   - Conversion of kernel messages to standard dev_*() in ctxfi
     driver.

Daniel Vetter fca52a5565 drm/i915: kerneldoc for interrupt enable/disable functions
Just start with the basics for now.

Since there's a lot of different functionality in i915_irq.c I've
decided to split it into different sections and pull in just the
relevant functions. Splitting into different files looks like a lot
more work since the interrupt handlers do an awful lot of reuse all
over.

v2: Rebase onto changed function names.

Daniel Vetter b680c37a4d drm/i915: DocBook integration for frontbuffer tracking
I shouldn't ask everyone to do this and fail myself ...

This extracts all the frontbuffer tracking functions into
intel_frontbuffer.c, adds a DOC overview section and also adds the
missing kerneldoc for i915_gem_track_fb and also pulls it into the
same section for convenience.

v2: Don't forget about the header files.

v3: Oops, might check compilation next time around. To make my life
easier drop the increase_pllclock from set_base_atomic since really,
it doesn't matter if you see your Oops or kgdb with a tiny bit of lag.

Ville Syrjälä 020178a1bc drm: Add drm_crtc_vblank_waitqueue()
Add a small static inline helper to grab the vblank wait queue based on
the drm_crtc.

This is useful for drivers to do internal vblank waits using
wait_event() & co.

v2: Pimp commit message (Daniel)
    Add kernel doc (Daniel)

Linus Torvalds a7d7a143d0 Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull DRM updates from Dave Airlie:
 "Like all good pull reqs this ends with a revert, so it must mean we
  tested it,

[ Ed. That's _one_ way of looking at it ]

  This pull is missing nouveau, Ben has been stuck trying to track down
  a very longstanding bug that revealed itself due to some other
  changes.  I've asked him to send you a direct pull request for nouveau
  once he cleans things up.  I'm away until Monday so don't want to
  delay things, you can make a decision on that when he sends it, I have
  my phone so I can ack things just not really merge much.

  It has one trivial conflict with your tree in armada_drv.c, and also
  the pull request contains some component changes that are already in
  your tree, the base tree from Russell went via Greg's tree already,
  but some stuff still shows up in here that doesn't when I merge my
  tree into yours.

  Otherwise all pretty standard graphics fare, one new driver and
  changes all over the place.

  New drivers:
   - sti kms driver for STMicroelectronics chipsets stih416 and stih407.

  core:
   - lots of cleanups to the drm core

Linus Torvalds e7fda6c4c3 Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer and time updates from Thomas Gleixner:
 "A rather large update of timers, timekeeping & co

   - Core timekeeping code is year-2038 safe now for 32bit machines.
     Now we just need to fix all in kernel users and the gazillion of
     user space interfaces which rely on timespec/timeval :)

   - Better cache layout for the timekeeping internal data structures.

   - Proper nanosecond based interfaces for in kernel users.

   - Tree wide cleanup of code which wants nanoseconds but does hoops
     and loops to convert back and forth from timespecs.  Some of it
     definitely belongs into the ugly code museum.

   - Consolidation of the timekeeping interface zoo.

   - A fast NMI safe accessor to clock monotonic for tracing.  This is a
     long standing request to support correlated user/kernel space
     traces.  With proper NTP frequency correction it's also suitable
     for correlation of traces accross separate machines.

   - Checkpoint/restart support for timerfd.

   - A few NOHZ[_FULL] improvements in the [hr]timer code.

   - Code move from kernel to kernel/time of all time* related code.

   - New clocksource/event drivers from the ARM universe.  I'm really
     impressed that despite an architected timer in the newer chips SoC
     manufacturers insist on inventing new and differently broken SoC
     specific timers.

[ Ed. "Impressed"? I don't think that word means what you think it means ]

   - Another round of code move from arch to drivers.  Looks like most
     of the legacy mess in ARM regarding timers is sorted out except for
     a few obnoxious strongholds.

   - The usual updates and fixlets all over the place"
