Clock registration must be performed before the component is
registered. aic32x4_component_probe attempts to get all the
clocks right off the bat. If the component is registered before
the clocks there is a race condition where the clocks may not
be registered by the time aic32x4_componet_probe actually runs.

The rt5670 codec driver uses DMI quirks to configure the DMIC data-pins,
which means that it knows which DMIC interface is used on a specific
device.
ATM we duplicate this DMI matching inside the UCM profiles to select
the right DMIC interface. Add a rt5670_components() helper which the
machine-driver can use to set the components string of the card so
that UCM can get the info from the components string.
This way we only need to add new DMI quirks in one place.

This patchset tries to resolve the diversity in the audio LED
control among the ALSA drivers. A new control layer registration
is introduced which allows to run additional operations on
top of the elementary ALSA sound controls.
A new control access group (three bits in the access flags)
was introduced to carry the LED group information for
the sound controls. The low-level sound drivers can just
mark those controls using this access group. This information
is not exported to the user space, but user space can
manage the LED sound control associations through sysfs
(last patch) per Mark's request. It makes things fully
configurable in the kernel and user space (UCM).
The actual state ('route') evaluation is really easy
(the minimal value check for all channels / controls / cards).
If there's more complicated logic for a given hardware,
the card driver may eventually export a new read-only
sound control for the LED group and do the logic itself.
The new LED trigger control code is completely separated
and possibly optional (there's no symbol dependency).
The full code separation allows eventually to move this
LED trigger control to the user space in future.
Actually it replaces the already present functionality
in the kernel space (HDA drivers) and allows a quick adoption
for the recent hardware (ASoC codecs including SoundWire).
snd_ctl_led 24576 0
The sound driver implementation is really easy:
1) call snd_ctl_led_request() when control LED layer should be
automatically activated
/ it calls module_request("snd-ctl-led") on demand /
2) mark all related kcontrols with
SNDRV_CTL_ELEM_ACCESS_SPK_LED or

to avoid same value writing. 'regmap_read' just read cache

When amp is internally shutdown by some reason, next 'AMP ON'

The call sequence in wm8960_configure_clocking is
ret = wm8960_configure_sysclk();
if (ret >= 0)
goto configure_clock;
....
ret = wm8960_configure_pll();
configure_clock:
...
wm8960_configure_sysclk is called before wm8960_configure_pll, as
there is bitclk relax on both functions, so wm8960_configure_sysclk
always return success, then wm8960_configure_pll() never be called.
With this case:
aplay -Dhw:0,0 -d 5 -r 48000 -f S24_LE -c 2 audio48k24b2c.wav
the required bitclk is 48000 * 24 * 2 = 2304000, bitclk got from
wm8960_configure_sysclk is 3072000, but if go to wm8960_configure_pll.
it can get correct bitclk 2304000.
So bitclk relax condition should be removed in wm8960_configure_sysclk,
then wm8960_configure_pll can be called, and there is also bitclk relax
function in wm8960_configure_pll.

Use the snd_soc_jack code to report jack events, instead of using extcon
for reporting the cable-type + an input_dev for reporting the button
presses.
The snd_soc_jack code will report the cable-type through both input_dev
events and through ALSA controls and the button-presses through input_dev
events.
Note that this means that when the codec drivers are moved over to use
the new arizona-jack.c library code instead of having a separate MFD
extcon cell with the extcon-arizona.c driver, we will no longer report
extcon events to userspace for cable-type changes. This should not be
a problem since "standard" Linux distro userspace does not (and has
never) used the extcon class interface for this. Android does have
support for the extcon class interface, but that was introduced in
the same release as support for input_dev cable-type events, so this
should not be a problem for Android either.
Note this also reduces ARIZONA_MAX_MICD_RANGE from 8 to 6, this is
ok to do since this info is always provided through pdata (or defaults)
and cannot be overridden from devicetree. All in-kernel users of the
pdata (and the fallback defaults) define 6 or less buttons/ranges.

Convert the arizona extcon driver into a helper library for direct use
from the arizona codec-drivers, rather then being bound to a separate
MFD cell.
Note the probe (and remove) sequence is split into 2 parts:
1. The arizona_jack_codec_dev_probe() function inits a bunch of
jack-detect specific variables in struct arizona_priv and tries to get
a number of resources where getting them may fail with -EPROBE_DEFER.
2. Then once the machine driver has create a snd_sock_jack through
snd_soc_card_jack_new() it calls snd_soc_component_set_jack() on
the codec component, which will call the new arizona_jack_set_jack(),
which sets up jack-detection and requests the IRQs.
This split is necessary, because the IRQ handlers need access to the
arizona->dapm pointer and the snd_sock_jack which are not available
when the codec-driver's probe function runs.
Note this requires that machine-drivers for codecs which are converted
to use the new helper functions from arizona-jack.c are modified to
create a snd_soc_jack through snd_soc_card_jack_new() and register
this jack with the codec through snd_soc_component_set_jack().

Drivers for MFD child-devices such as the arizona codec drivers
and the arizona-extcon driver can choose to either make
runtime_pm_get/_put calls on their own child-device, which will
then be propagated to their parent; or they can make them directly
on their MFD parent-device.
The arizona-extcon code was using runtime_pm_get/_put calls on
its own child-device where as the codec drivers are using
runtime_pm_get/_put calls on their parent.
The arizona-extcon MFD cell/child-device has been removed and this
commit is part of refactoring the arizona-extcon code into a library
to be used directly from the codec drivers.
Specifically this commit moves the code over to make
runtime_pm_get/_put calls on the parent device (on arizona->dev)
bringing the code inline with how the codec drivers do this.
Note this also removes the pm_runtime_enable/_disable calls
as pm_runtime support has already been enabled on the parent-device
by the arizona MFD driver.
This is part of a patch series converting the arizona extcon driver into
a helper library for letting the arizona codec-drivers directly report
jack state through the standard sound/soc/soc-jack.c functions.

>From Datasheet, the PLL performs best when f2 is between
