936b9df7a5 ASoC: Intel: Skylake: Replace zero-length array with flexible-array
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

This issue was found with the help of Coccinelle.

7693cadac8 ASoC: Intel: Skylake: Await purge request ack on CNL
Each purge request is sent by driver after master core is powered up and
unresetted but before it is unstalled. On unstall, ROM begins processing
the request and initializing environment for FW load. Host should await
ROM's ack before moving forward. Without doing so, ROM init poll may
start too early and false timeouts can occur.

2ef81057d8 ASoC: Intel: Skylake: Remove superfluous chip initialization
Skylake driver does the controller init operation twice:
- first during probe (only to stop it just before scheduling probe_work)
- and during said probe_work where the actual correct sequence is
executed

To properly complete boot sequence when iDisp codec is present, bus
initialization has to be called only after _i915_init() finishes.
With additional _reset_list preceding _i915_init(), iDisp codec never
gets the chance to enumerate on the link. Remove the superfluous
initialization to address the issue.

Pull sound updates from Takashi Iwai:
 "As the diffstat shows we've had again a lot of works done for this
  cycle: the majority of changes are the continued componentization and
  code refactoring in ASoC, the tree-wide PCM API updates and cleanups
  and SOF updates while a few ASoC driver updates are seen, too.

  Here we go, some highlights:

  Core:
   - Finally y2038 support landed to ALSA ABI; some ioctls have been
     extended and lots of tricks were applied
   - Applying the new managed PCM buffer API to all drivers; the API
     itself was already merged in 5.5
   - The already deprecated dimension support in ALSA control API is
     dropped completely now
   - Verification of ALSA control elements to catch API misuses

  ASoC:
   - Further code refactorings and moving things to the component level
   - Lots of updates and improvements on SOF / Intel drivers; now
     including common HDMI driver and SoundWire support
   - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
     WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011,
     RT1015 and RT1308

  HD-audio:
   - Improved ring-buffer communications using waitqueue
   - Drop the superfluous buffer preallocation on x86

  Others:
   - Many code cleanups, mostly constifications over the whole tree
   - USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix
   - FireWire: code refactoring for oxfw and dice drivers"

82d9d54a6c ALSA: hda: add Intel DSP configuration / probe code
For distributions, we need one place where we can decide
which driver will be activated for the auto-configation of the
Intel's HDA hardware with DSP. Actually, we cover three drivers:

* Legacy HDA
* Intel SST
* Intel Sound Open Firmware (SOF)

All those drivers registers similar PCI IDs, so the first
driver probed from the PCI stack can win. But... it is not
guaranteed that the correct driver wins.

This commit changes Intel's NHLT ACPI module to a common
DSP probe module for the Intel's hardware. All above sound
drivers calls this code. The user can force another behaviour
using the module parameter 'dsp_driver' located in
the 'snd-intel-dspcfg' module.

This change allows to add specific dmi checks for the specific
systems. The examples are taken from the pull request:

3507bb5fe4 ASoC: intel: skl-pcm: remove snd_pcm_ops
snd_pcm_ops is no longer needed.
Let's use component driver callback.

*Note*

Only Intel skl-pcm has .get_time_info implementation, but ALSA SoC
framework doesn't call it so far.
To keep its implementation, this patch keeps .get_time_info,
but it is still not called.
Intel guy need to support it in the future.

36004c42c7 ASoC: Intel: Skylake: large_config_get overhaul
LARGE_CONFIG_GET is mainly used to retrieve requested module parameters
but it may also carry TX payload with them. Update its implementation to
account for both TX and RX data.
First reply.header carries total payload size within data_off_sizefield.
Make use of reply.header to realloc returned buffer with correct size.

Failure of IPC request is permissive - error-payload may be returned, an
informative data why GET for given param failed - and thus function
should not collapse before entire processing is finished. Caller is
responsible for checking returned payload and bytes parameters.

19abfefd4c ALSA: hda: Direct MMIO accesses
HD-audio drivers access to the mmio registers indirectly via the
corresponding bus->io_ops callbacks.  This is because some platform
(notably Tegra SoC) requires the word-aligned access.  But it's rather
a rare case, and other platforms suffer from the penalties by indirect
calls unnecessarily.

This patch is an attempt to optimize and cleanup for this situation.
Now the special aligned access is used only when a new kconfig
CONFIG_SND_HDA_ALIGNED_MMIO is set.  And the HD-audio core itself
provides the aligned MMIO access helpers instead of the driver side.
If Kconfig isn't set (as default), the standard helpers like readl()
or writel() are used directly.

A couple of places in ASoC Intel drivers have the access via io_ops
reg_writel(), and they are replaced with the direct writel() calls.

And now with this patch, the whole bus->io_ops becomes empty, so it's
dropped completely.  The bus initialization functions are changed
accordingly as well to drop the whole bus->io_ops.

619a1f195f ALSA: hda: Remove page allocation redirection
The HD-audio core allocates and releases pages via driver's specific
dma_alloc_pages and dma_free_pages ops defined in bus->io_ops.  This
was because some platforms require the uncached pages and the handling
of page flags had to be done locally in the driver code.

Since the recent change in ALSA core memory allocator, we can simply
pass SNDRV_DMA_TYPE_DEV_UC for the uncached pages, and the only
difference became about this type to be passed to the core allocator.
That is, it's good time for cleaning up the mess.

This patch changes the allocation code in HD-audio core to call the
core allocator directly so that we get rid of dma_alloc_pages and
dma_free_pages io_ops.  If a driver needs the uncached pages, it has
to set bus->dma_type right after the bus initialization.

This is merely a code refactoring and shouldn't bring any behavior
changes.

abf31feea2 ASoC: Intel: Update request-reply IPC model
struct ipc_message contains fields: header, tx_data and tx_size which
represent TX i.e. request while RX is represented by rx_data and rx_size
with reply's header equivalent missing.

Reply header may contain some vital information including, but not
limited to, received payload size. Some IPCs have entire payload found
within RX header instead. Content and value of said header is context
dependent and may vary between firmware versions and target platform.
Current model does not allow such IPCs to function at all.

Rather than appending yet another parameter to an already long list of
such for sst_ipc_tx_message_XXXs, declare message container in form of
struct sst_ipc_message and add them to parent's ipc_message declaration.

Align haswell, baytrail and skylake with updated request-reply model and
modify their reply processing functions to save RX header within message
container. Despite the range of changes, status quo is achieved.

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

Also, if a debugfs call fails, userspace is notified with an error in
the log, so no need to log the error again.
