ALSA: dice: Split stream functionality into a file
This commit adds a file with some helper functions for streaming, and move some
codes into the file with some arrangements.
Well-known CMP is not used to start/stop streams for Dice chipset. It's
achieved by writing to specific address. We call this way as 'enable'.
When devices are 'enabled', streaming starts in registered isochronous channel.
Some helper functions are already implemented in previous commit.
Basically, the stream is compliant to IEC 61883-6, so-called as AMDTP. But Dice
has a specific quirk, so called-as 'Dual Wire'. This quirk is applied at
176.4/192.0kHz. In this mode, each packet includes double number of events than
number in the specification, and stream runs at a half of sampling rate.
There is another quirk at bus reset. Dice chipset handles drivers' request but
don't re-enable streaming. So stream should be stopped.

ALSA: dice: Split transaction functionality into a file
This commit adds a file with some helper functions for transaction, and move
some codes into the file with some arrangements.
For Dice chipset, well-known FCP or AV/C commands are not used to control
devices. It's achieved by read/write transactions into specific addresses.
Dice's address area is split into 5 areas. Each area has its own role. The
offset for each area can be got by reading head of the address area. By
reading these areas, drivers can get to know device status. By writing these
areas, drivers can change device status.
Dice has a specific mechanism called as 'notification'. When device status is
changed, Dice devices tells the event by sending transaction. This notification
is sent to an address which drivers register in advance. But this causes an
issue to drivers.
To handle the notification, drivers need to allocate its own callback function
to the address region in host controller. This region is exclusive. For the
other applications, drivers must give a mechanism to read the received
notification. For this purpose, Dice driver already implements hwdep interface.
Dice chipset doesn't allow drivers to register several addresses. In this
reason, when this driver is applied to a device, the other drivers should
_not_ try to register its own address to the device.

Denon/Marantz USB DACs need a specific vendor command to switch between PCM and

This patch applies to the following devices:
- Marantz SA-14S1
- Marantz HD-DAC1
User can pass snoop option to enable/disable the snoop behavior, but
currently azx_check_snoop_available() always turns it off for some
devices. For better debuggability, change the parameter as bint, and
allow user to enable/disable forcibly the snoop when specified via the
module option.
Add a new driver_caps bit, AZX_DCAPS_SNOOP_OFF, to set the snoop off
as default. This new bit is used for the checks in
azx_check_snoop_available(). Most of case-switches are replaced with
the new dcaps in each entry.
While working on it, for avoiding to spend more bits, combine three
bits AZX_DCAPS_SNOOP_SCH, AZX_DCAPS_SNOOP_ATI and
AZX_DCAPS_SNOOP_NVIDIA bits into a flat type of two bits. This
reduces the bits usages, and assign AZX_DCAPS_OFF to this empty bit

Sasha Levin reports:
"gcc5 changes the default standard to c11, which makes kernel build
unhappy
Explicitly define the kernel standard to be gnu89 which should keep
everything working exactly like it was before gcc5"
There are multiple small issues with the new default, but the biggest
issue seems to be that the old - and very useful - GNU extension to
allow a cast in front of an initializer has gone away.
Patch updated by Kirill:
"I'm pretty sure all gcc versions you can build kernel with supports
-std=gnu89. cc-option is redunrant.
We also need to adjust HOSTCFLAGS otherwise allmodconfig fails for me"
Note by Andrew Pinski:
"Yes it was reported and both problems relating to this extension has
been added to gnu99 and gnu11. Though there are other issues with the
kernel dealing with extern inline have different semantics between
gnu89 and gnu99/11"
End result: we may be able to move up to a newer stdc model eventually,
but right now the newer models have some annoying deficiencies, so the
traditional "gnu89" model ends up being the preferred one.

performance regression in some LKP test cases. The changes are
reverted for now. It'll probably be retried once threaded IRQ

Pull ACPI and power management fixes from Rafael Wysocki:
"These are three regression fixes, two recent (generic power domains,
suspend-to-idle) and one older (cpufreq), an ACPI blacklist entry for
one more machine having problems with Windows 8 compatibility, a minor
cpufreq driver fix (cpufreq-dt) and a fixup for new callback
definitions (generic power domains).
Specifics:
- Fix a crash in the suspend-to-idle code path introduced by a recent
commit that forgot to check a pointer against NULL before
dereferencing it (Dmitry Eremin-Solenikov).
- Fix a boot crash on Exynos5 introduced by a recent commit making
that platform use generic Device Tree bindings for power domains
which exposed a weakness in the generic power domains framework
leading to that crash (Ulf Hansson).
- Fix a crash during system resume on systems where cpufreq depends
on Operation Performance Points (OPP) for functionality, but
CONFIG_OPP is not set. This leads the cpufreq driver registration
to fail, but the resume code attempts to restore the pre-suspend
cpufreq configuration (which does not exist) nevertheless and
crashes. From Geert Uytterhoeven.
- Add a new ACPI blacklist entry for Dell Vostro 3546 that has
problems if it is reported as Windows 8 compatible to the BIOS
(Adam Lee).
- Fix swapped arguments in an error message in the cpufreq-dt driver
(Abhilash Kesavan).
- Fix up the prototypes of new callbacks in struct generic_pm_domain
to make them more useful. Users of those callbacks will be added
in 3.19 and it's better for them to be based on the correct struct
definition in mainline from the start. From Ulf Hansson and Kevin
