The wm8997 is a compact, high-performance audio hub CODEC with SLIMbus
interfacing, for smartphones, tablets and other portable audio devices
based on the Arizona platform.
This patch integrates the wm8997 into the Arizona mfd.

When the device is used with an external DCVDD supply instead of the
internal LDO1 then an extra step is required when suspending and resuming
the device.

Running HPDET while the headphone outputs are enabled can disrupt the
operation of HPDET. In order to avoid this HPDET needs to disable the
headphone outputs and ASoC needs to not enable them while HPDET is
running.
Do the ASoC side of this by storing the enable state in the core driver
structure and only writing to the device if a flag indicating that the
accessory detection side is in a state where it can have the headphone
output stage enabled.

Newer Arizona devices include a microphone clamp function which is tied to
jack detect. Activate this feature when present in order to ensure best
performance of the subsystem.

Some other device functions need to integrate with signal sources in the
audio portion (primarily for haptics) so allow CODEC to export the DAPM
context by pointing to it from the core driver.

The WM5110 is a highly-integrated low-power audio system for smartphones,
tablets and other portable audio devices. It combines an advanced DSP
feature set with a flexible, high-performance audio hub CODEC.
The support is based on the Arizona core driver.

Rather than open coding the enable GPIO control in the MFD core use the
API to push the management on to the regulator driver. The immediate
advantage is slight for most systems but this will in future allow device
configurations where an external regulator is used for DCVDD.

Several forthcoming Wolfson devices are based on a common platform
known as Arizona allowing a great deal of reuse of driver code. This
patch adds core support for these devices.
In order to handle systems which do not use the generic clock API a
simple wrapper for the 32kHz clock domain in the devices is provided.
Once the generic clock API is widely available this code will be moved
over to use that.
For simplicity some WM5102 specific code is included in the core driver,
the effort involved in splitting the device out isn't worth it.
