ASoC: soc-pcm: fix regression in soc_new_pcm()

Commit af4bac11531f ("ASoC: soc-pcm: crash in snd_soc_dapm_new_dai")
swapped the SNDRV_PCM_STREAM_* parameter in the
snd_soc_dai_stream_valid(cpu_dai, ...) checks. But that works only
for codec2codec links. For normal links it breaks registration of
playback/capture-only PCM devices.

E.g. on qcom/apq8016_sbc there is usually one playback-only and one
capture-only PCM device, but they disappeared after the commit.

The codec2codec case was added in commit a342031cdd08
("ASoC: create pcm for codec2codec links as well") as an extra check
(e.g. `playback = playback && cpu_playback->channels_min`).

We should be able to simplify the code by checking directly for
the correct stream type in the loop.
This also fixes the regression because we check for PLAYBACK for
both codec and cpu dai again when codec2codec is not used.

ASoC: soc-pcm: tidyup soc_pcm_open() order

soc_pcm_open() operation order is not good.
At first, soc_pcm_open() operation order is

1) CPU DAI startup
2) Component open
3) Codec DAI startup
4) rtd startup

But here, 2) will call try_module_get() if component has
module_get_upon_open flags. This means 1) CPU DAI startup
will be operated *before* its module was loaded.
DAI should be called *after* Component.

Second, soc_pcm_close() operation order is
1) CPU DAI shutdown
2) Codec DAI shutdown
3) rtd shutdown
4) Component close

soc_pcm_open() and soc_pcm_close() are paired function,
but, its operation order is unbalance.
This patch tidyup soc_pcm_open() order to Component -> rtd -> DAI.

ASoC: SOF: Move DSP power state transitions to platform-specific ops

The DSP device substates such as D0I0/D0I3
are platform-specific. Therefore, the d0_substate
field of struct snd_sof_dev is replaced
with the dsp_power_state field which represents the current
state of the DSP. This field holds both the device state
and the platform-specific substate values.

With the DSP device substates being platform-specific,
the DSP power state transitions need to be performed in
the platform-specific suspend/resume ops as well.

In order to achieve this, the ops signature has to be
modified to pass the target device state as an
argument. The target substate will be determined by
the platform-specific ops before performing the transition.
For example, in the case of the system suspending to S0IX,
the top-level SOF device suspend callback needs to
only determine if the DSP will be entering
D3 or remain in D0. The target substate in case the device
needs to remain in D0 (D0I0 or D0I3) will be determined
by the platform-specific suspend op.

With the addition of the extended set of power states for the DSP,
the set_power_state op for HDA platforms has to be extended
to handle only the appropriate state transitions. So, the
implementation for the Intel HDA platforms is also modified.

ASoC: Use imply for SND_SOC_ALL_CODECS

Currently SND_SOC_ALL_CODECS selects the config symbols for all codec
drivers.  As "select" bypasses dependencies, lots of "select" statements
need explicit dependencies, which are hard to get right, and hard to
maintain[*].

Fix this by using "imply" instead, which is a weak version of "select",
and which obeys dependencies of target symbols.

Add dependencies to invisible symbols that are currently selected only
if their dependencies are fulfilled.

ASoC: SOF: Intel: hda: fix ordering bug in resume flow

When HDA controller is resumed from suspend, i915 HDMI/DP
codec requires that following order of actions is kept:

 - i915 display power up and configuration of link params
 - hda link reset and setup

Current SOF HDA code delegates display codec power control
to the codec driver. This works most of the time, but in
runtime PM sequences, the above constraint may be violated.
On platforms where BIOS values for HDA link parameters do
not match hardware reset defaults, this may lead to errors
in HDA verb transactions after resume.

Fix the issue by explicitly powering the display codec
in the HDA controller resume/suspend calls, thus ensuring
correct ordering. Special handling is needed for the D0i3
flow, where display power must be turned off even though
DSP is left powered.

Now that we have more invocations of the display power helper
functions, the conditional checks surrounding each call have
been moved inside hda_codec_i915_display_power(). The two
special cases of display powering at initial probe are handled
separately. The intent is to avoid powering the display whenever
no display codecs are used.

Note that early powering of display was removed in
commit 687ae9e287b3 ("ASoC: intel: skl: Fix display power regression").
This change was also copied to the SOF driver. No failures
have resulted as hardware default values for link parameters
have worked out of the box. However with recent i915 driver
changes like done in commit 87c1694533c9 ("drm/i915: save
AUD_FREQ_CNTRL state at audio domain suspend"), this does not
hold anymore and errors are hit.

Merge tag 'zonefs-5.6-rc1' of git://git./linux/kernel/git/dlemoal/zonefs

Pull new zonefs file system from Damien Le Moal:
 "Zonefs is a very simple file system exposing each zone of a zoned
  block device as a file.

  Unlike a regular file system with native zoned block device support
  (e.g. f2fs or the on-going btrfs effort), zonefs does not hide the
  sequential write constraint of zoned block devices to the user. As a
  result, zonefs is not a POSIX compliant file system. Its goal is to
  simplify the implementation of zoned block devices support in
  applications by replacing raw block device file accesses with a richer
  file based API, avoiding relying on direct block device file ioctls
  which may be more obscure to developers.

  One example of this approach is the implementation of LSM
  (log-structured merge) tree structures (such as used in RocksDB and
  LevelDB) on zoned block devices by allowing SSTables to be stored in a
  zone file similarly to a regular file system rather than as a range of
  sectors of a zoned device. The introduction of the higher level
  construct "one file is one zone" can help reducing the amount of
  changes needed in the application while at the same time allowing the
  use of zoned block devices with various programming languages other
  than C.

  Zonefs IO management implementation uses the new iomap generic code.
  Zonefs has been successfully tested using a functional test suite
  (available with zonefs userland format tool on github) and a prototype
  implementation of LevelDB on top of zonefs"

irqchip/gic-v4.1: Avoid 64bit division for the sake of 32bit ARM

In order to allow the GICv4 code to link properly on 32bit ARM,
make sure we don't use 64bit divisions when it isn't strictly
necessary.

Merge tag 'x86-urgent-2020-02-09' of git://git./linux/kernel/git/tip/tip

Pull x86 fixes from Thomas Gleixner:
 "A set of fixes for X86:

   - Ensure that the PIT is set up when the local APIC is disable or
     configured in legacy mode. This is caused by an ordering issue
     introduced in the recent changes which skip PIT initialization when
     the TSC and APIC frequencies are already known.

   - Handle malformed SRAT tables during early ACPI parsing which caused
     an infinite loop anda boot hang.

   - Fix a long standing race in the affinity setting code which affects
     PCI devices with non-maskable MSI interrupts. The problem is caused
     by the non-atomic writes of the MSI address (destination APIC id)
     and data (vector) fields which the device uses to construct the MSI
     message. The non-atomic writes are mandated by PCI.

     If both fields change and the device raises an interrupt after
     writing address and before writing data, then the MSI block
     constructs a inconsistent message which causes interrupts to be
     lost and subsequent malfunction of the device.

     The fix is to redirect the interrupt to the new vector on the
     current CPU first and then switch it over to the new target CPU.
     This allows to observe an eventually raised interrupt in the
     transitional stage (old CPU, new vector) to be observed in the APIC
     IRR and retriggered on the new target CPU and the new vector.

     The potential spurious interrupts caused by this are harmless and
     can in the worst case expose a buggy driver (all handlers have to
     be able to deal with spurious interrupts as they can and do happen
     for various reasons).

   - Add the missing suspend/resume mechanism for the HYPERV hypercall
     page which prevents resume hibernation on HYPERV guests. This
     change got lost before the merge window.

   - Mask the IOAPIC before disabling the local APIC to prevent
     potentially stale IOAPIC remote IRR bits which cause stale
     interrupt lines after resume"
