The PLL is disabled when the corresponding bit is set not the other
way around. This commit depends on my other commit with Subject
"ASoC: WM8804: Refactor set_pll code to avoid GCC warnings".

GPIO2 and GPIO3 on the WM8962 are MFPs and need to be put into GPIO mode
before the GPIO block can be used to control them. We're already doing
this when used via gpiolib, factor out the code for use when setting static
configurations via platform data as well.

Allow microphone detection on WM8962 to be performed using the interrupt
signal, allowing the detection of both microphone presence and button
presses with a signal singal from the CODEC to CPU. Currently a 250ms
debounce time is applied to both short circuit and presence detection,
this has not been optimised.

While it is a generic serial port in practice the i.MX SSI is only supported
in Linux as an audio port (the i.MX has dedicated SPI controllers and so on).
This means we don't need to disambiguate against other uses of the hardware
and so can drop the -dai suffix from the driver name which fixes merge
issues with the i.MX tree in -next.

The restrictions on configuring BCLK are overly cautious, other constraints
in the system should ensure that reconfiguration is not possible when the
device is sufficiently active to be unable to support reclocking.

Add the widget for MICBIAS power control and allow configuration of the
microphone bias setup via the platform data for the WM8962. When
microphone status signals are brought out to GPIO this should be
sufficient to enable microphone detection.

When configuring the FLL we preserve the FLL enable configuration in order
to allow us to reenable the FLL after configuration but we do not clear
the other bits in the register, causing old configuration to be preserved.

The code can't really cope with I/O errors, so it would be better
to be consistent throughout all cache functions and return -1 instead
of -EINVAL.
The return value of snd_soc_read(...) is mostly checked in the probe
function and nowhere else.

rtd->dev.init_name is set twice in soc_probe_dai_link. I removed the first

changes and usually dai_link->name seems to fit anyway better for a sysfs

Now codec hits the SND_SOC_BIAS_OFF also when it is idle. This is also
the default state after probing and codec is left unconfigured and
unpowered by default. Initialization will happen when the bias state changes
and aic3x_set_power does power-up and cache sync.

There is no need to reset the codec and perform cache sync if none of the
supply regulators were not disabled. Patch registers a notifier callback for
each supply and callback then sets a flag to indicate when cache sync is
required.
HW writes are also needless when codec bias is off so cache_only flag is set
independently of actual supply regulators state.

Now all the regulators are disabled when entering into SND_SOC_BIAS_OFF
and enabled when coming back to SND_SOC_BIAS_STANDBY state. Currently this
runtime control happens only with suspend/resume as this patch does not
change the default idle behavior.
This patch manages all the regulators and reset since it seems that register
sync is needed even if only analog supplies AVDD and DRVDD are disabled.
This was noted when the system was running with idle behavior changed and
IOVDD and DVDD were on.
It is not known are all the registers needed to sync or only some subset of
them. Therefore patch plays safe and does always full shutdown/power-up.

Purpose of this virtual Detection pin is to keep codec bias on whenever the
GPIO or jack detection features are needed.
Jack detection needs a mic bias so machine drivers can construct a following
route for instance for keeping the path and codec bias on:
"Input Jack" -> "Mic Bias xV" -> "Detection" -> detection block inside codec.
For the GPIO the machine driver can force the pin on with
snd_soc_dapm_force_enable_pin.
