ASoC: Add snd_soc_of_put_dai_link_codecs() helper function
The code for dereferencing device nodes in the 'codecs' array is moved
to a separate function so we can avoid open coding that in drivers.

ASoC: soc-io: Fix snd_soc_component_update_bits_legacy
After the codec to component conversion codecs with custom read/write
function will no longer able to use update_bits as their io callbacks are
registered at component->driver level and not in component level.

To not complicate the code further, lets just use the
snd_soc_component_read/snd_soc_component_write function and let them sort
out the correct io function to call.

ASoC: da7219: Add common clock usage for providing DAI clks
There is a need to use DA7219 as DAI clock master for other codecs
within a system, which means that the DAI clocks are required to
remain, regardless of whether the codec is actually running
playback/capture. To be able to expose control of the DAI clocking
the common clock framework has been employed.

The current implementation adds a simple clock gate for enabling
and disabling the DAI clocks, with no rate control supported
(this is still handled through standard hw_params() functions as
before). If DT is enabled then the clock is added to the OF
providers list, otherwise a clkdev lookup is used.

ASoC: Intel: bytcr_rt5651: Change defaults to enable jack-detect, analog mics
Change the default quirk settings to enable jack-detect, analog mics.

The old default input mapping of DMIC for non Bay Trail CR devices seems
like a poor default as I'm not aware of any Intel SST + rt5651 using
devices with a DMIC.

All Cherry Trail devices using the bytcr_rt5651 machine driver seem to be
modelled after BYT-CR devices, And the only non CR Bay Trail devices with
a rt5651 codec I'm aware of are the Minnow boards for which we already have
board specific quirks. So it seems better to me to use the BYT-CR defaults
everywhere.

This e.g. makes the Chuwi Hi8 Pro (CWI513) work ootb without needing a
quirk.

ASoC: Intel: bytcr_rt5651: Add support for Bay Trail CR / SSP0 using boards
Despite its name being prefixed with bytcr, before this commit the
bytcr_rt5651 machine driver could not work with Bay Trail CR boards,
as those only have SSP0 and it only supported SSP0-AIF1 setups.

This commit adds support for this, autodetecting AIF1 vs AIF2 based on
BIOS tables.

While at it also add support for SSP2-AIF2 setups, as that requires only
minimal extra code on top of the code adding SSP0-AIF1 / SSP0-AIF2 support.

Note this code is all copy-pasted from bytcr_rt5640.c. I've looked into
merging the 2 machine drivers into 1 to avoid copy-pasting, but there are
enough subtile differences to make this hard *and* with all the quirks the
machine driver already is full with if (variant-foo) then ... else ...
constructs adding more of these is going to make the code unreadable.

change. If we really want the DMIC_EN behavior anywhere it should be

ASoC: rt5651: Make rt5651_apply_properties() private
The idea behind exporting rt5651_apply_properties(), was for it to be used
on platforms where the platform code may need to add device-properties,
rather then relying only on properties set by the firmware. The platform
code could then call rt5651_apply_properties() after adding properties to
make sure that the codec driver was aware of the new properties.

But this is not necessary, as long as we do all property parsing from
the codec component-driver's probe function (or later) then the machine
driver can attach properties before calling snd_soc_register_card and
calling rt5651_apply_properties() for ordering reasons is not necessary.

This commit makes rt5651_apply_properties() private and adds 2 comments
documenting that all property parsing must be done from the codec
component-driver's probe function.

ASoC: Intel: Skylake: Add BE DAI for WoV usecase
Currently DMIC capture and WoV usecase uses same BE DAI but operate at
different sampling rates, this results in config mismatch for WoV when
DMIC is already running in parallel.

DMIC has two slots which can operate with some constraints, so add BE
DAI for DMICvoice pin which can used for WoV usecases to capture 4ch,
16KHz, 16bit data.

ASoC: Intel: Skylake: Refine skl widget type check
The current check is not effective when all the widgets of a card are
involved since other widgets also can be of same type. So, make widget
type check more stringent by checking dev pointer additionally.

ASoC: rt5514: Fix uninitialized calibration value
With gcc-4.1.2, if CONFIG_SND_SOC_RT5514_SPI is not set:

    sound/soc/codecs/rt5514.c: In function ‘rt5514_dsp_voice_wake_up_put’:
    sound/soc/codecs/rt5514.c:363: warning: ‘buf[0]’ is used uninitialized in this function
    sound/soc/codecs/rt5514.c:363: warning: ‘buf[1]’ is used uninitialized in this function
    sound/soc/codecs/rt5514.c:363: warning: ‘buf[2]’ is used uninitialized in this function
    sound/soc/codecs/rt5514.c:363: warning: ‘buf[3]’ is used uninitialized in this function

Fix this by initializing the buffer with zeroes, to avoid random bits
being written to the calibration register later.

ASoC: rt5514: Fix rt5514_spi_burst_read() buffer passing
rt5514_dsp_voice_wake_up_put() passes "(u8 *)&buf" to
rt5514_spi_burst_read(), where the cast is needed to silence a compiler
warning:

    sound/soc/codecs/rt5514.c: In function ‘rt5514_dsp_voice_wake_up_put’:
    sound/soc/codecs/rt5514.c:357: warning: passing argument 2 of ‘rt5514_spi_burst_read’ from incompatible pointer type

However, as the variable is declared as an array ("u8 buf[8]"), the
function should just pass "buf" instead.
