ASoC: da7219: Add recalc_rate function to return DAI clock rate
By making MCLK parent of DAI clocks, when querying the rate of the
clock the rate returned is now given from the parent clock so
gives the MCLK rate rather than 0 as previously returned. This is
a bit misleading, and actually there's no major reason why we can't
at least return the DAI WCLK rate, as set in HW, so that's what we
now do.

ASoC: da7219: MCLK should be enabled before DAI clocks
For platforms using the Common Clock Framework to control the
codec's DAI clocks, MCLK should be enabled prior to DAI clocks
being turned on. For some platforms the codec is already
provided with an MCLK reference and can therefore control MCLK
itself as it needs to.

To improve functionality MCLK is now added as a parent to the
DAI clocks, if MCLK was provided, so that if they are enabled MCLK
will automatically be enabled as a prerequisite by the CCF.

ASoC: rt274: Variable "buf" in function rt274_jack_detect() could be uninitialized
In function rt274_jack_detect(), local variable "buf" could
be uninitialized if function regmap_read() returns -EINVAL.
However, it will be used to calculate "hp" and "mic" and
make their value unpredictable while those value are used
in the caller. This is potentially unsafe.

ASoC: Intel: bytcr_rt5651: Add quirk for PoV TAB-P1006W-232 (v1.0) tablet
Add a DMI quirk for the Point of View TAB-P1006W-232 (v1.0) tablet, this
tablet is special in a number of ways:

1) It uses the 2nd GPIO resource in the ACPI tables for jack-detect rather
then using the rt5651 codec's builtin jack-detect functionality

2) It uses the 3th GPIO resource in the ACPI tables to control the
external amplifier rather then the usual first non GpioInt resource and
the GPIO is active-low.

3) It is a BYTCR device, without a CHAN package and it uses SSP0-AIF1
rather then the default SSP0-AIF2.

4) Its internal mic is a digital mic (the first x86 rt5651 device that
I'm aware of which does this), combined with having its headset-mic
connected to IN2.

ASoC: Intel: bytcr_rt5651: Revert "Fix DMIC map headsetmic mapping"
Commit 37c7401e8c1f ("ASoC: Intel: bytcr_rt5651: Fix DMIC map
headsetmic mapping"), changed the headsetmic mapping from IN3P to IN2P,
this was based on the observation that all bytcr_rt5651 devices I have
access to (7 devices) where all using IN3P for the headsetmic. This was
an attempt to unifify / simplify the mapping, but it was wrong.

None of those devices was actually using a digital internal mic. Now I've
access to a Point of View TAB-P1006W-232 (v1.0) tabler, which does use a
DMIC and it does have its headsetmic connected to IN2P, showing that the
original mapping was correct, so this commit reverts the change changing
the mapping back to IN2P.

ASoC: rt5651: Add support for jack detect using an external GPIO
Some board designs hook the jack-detect up to an external GPIO,
rather then to one of the codec pins, add support for this.

Figuring out which GPIO to use is pretty much board specific so I've
chosen to let the machine driver pass the gpio_desc as data argument to
snd_soc_component_set_jack() rather then add support for getting the
GPIO to the codec driver. This keeps the codec code nice and clean.

Note that using an external GPIO for this conflicts with button-press
support, so this commit disables button-press support when an
external GPIO is used.

ASoC: rt5651: Add ACPI ID 10EC5640
Some BYT platforms have a RT5651 codec while using an ACPI node with
a HID of 10EC5640 to describe the coded. Add the 10EC5640 HID to the
acpi_device_id list, so that the rt5651 will bind to the codec on these
devices.

Like the rt5645 and rt5670 drivers which also have the 10EC5640 ACPI HID
in their acpi_device_id list for similar reasons, the rt5651 driver checks
the codecs device-id register so that it will only bind if the codec
actually is a rt5651 and it will ignore actual rt5640 codecs.

ASoC: tlv320aic32x4: Kernel OOPS while entering DAPM standby mode
During the bootup of the kernel, the DAPM bias level is in the OFF
state. As soon as the DAPM framework kicks in it pushes the codec
into STANDBY state.

The probe function doesn't prepare the clock, and STANDBY state
does a clk_disable_unprepare() without checking the previous state.
This leads to an OOPS.

Not transitioning from an OFF state to the STANDBY state fixes the
problem.

ASoC: ak4458: Add support for AK4497
AK4497 is a 32-bit 2ch DAC and has the same register
map as AK4458 with few exceptions:

* AK4497 has one more register at the end of register space
  DFS_READ which is a read only register that allows users
  to read FS Auto Detection mode. We currently do not use
  this register so we use the same regmap structure as for ak4458.

* Because AK4458 is an 8ch DAC there are some fields that are
  only used by AK4458 and marked as reserved for AK4497, so for
  this reason we need to have a distinct set of controls, widgets
  and routes.

Datasheet for AK4497 is at:
https://www.akm.com/akm/en/file/ev-board-manual/AK4497EQ.pdf

574823bfab Change mincore() to count "mapped" pages rather than "cached" pages
The semantics of what "in core" means for the mincore() system call are
somewhat unclear, but Linux has always (since 2.3.52, which is when
mincore() was initially done) treated it as "page is available in page
cache" rather than "page is mapped in the mapping".

The problem with that traditional semantic is that it exposes a lot of
system cache state that it really probably shouldn't, and that users
shouldn't really even care about.

So let's try to avoid that information leak by simply changing the
semantics to be that mincore() counts actual mapped pages, not pages
that might be cheaply mapped if they were faulted (note the "might be"
part of the old semantics: being in the cache doesn't actually guarantee
that you can access them without IO anyway, since things like network
filesystems may have to revalidate the cache before use).

In many ways the old semantics were somewhat insane even aside from the
information leak issue.  From the very beginning (and that beginning is
a long time ago: 2.3.52 was released in March 2000, I think), the code
had a comment saying

  Later we can get more picky about what "in core" means precisely.

and this is that "later".  Admittedly it is much later than is really
comfortable.

NOTE! This is a real semantic change, and it is for example known to
change the output of "fincore", since that program literally does a
mmmap without populating it, and then doing "mincore()" on that mapping
that doesn't actually have any pages in it.

I'm hoping that nobody actually has any workflow that cares, and the
info leak is real.

We may have to do something different if it turns out that people have
valid reasons to want the old semantics, and if we can limit the
information leak sanely.
