If we get an indeterminate impedance with both headset polarities then
give up and report the accessory as a headphone rather than continually
retrying.

Using pm_runtime to decide if the device should go into full power down
has the dual advantage of allowing easier integration with non-DAPM
reasons to power on the device (like the FLL) and allowing userspace to
control the final power down which is useful for tuning retention of
DSP firmware.

We need to write the configuration for each microphone to a different

When we have identified an accessory make sure we've flagged that we've
done so in order to make sure we always report buttons and don't continue
to polarity flip.

This is more what the device model wants us to do and will allow use by
non-audio functions before the audio part of the device has come up.

This will allow us to move the interrupt allocation out of the ASoC part
of the driver and simplifies the locking by removing any reliance in the
bulk of the interrupt path on the big CODEC lock.

These are all to either uncached registers or fixes to register defaults,
in the former case the cache won't do anything and in the latter case
we're fixing things so the cache sync will do the right thing.

Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure")
introduced the possibility to have constant DAI ops structures, yet this is
barley used in both existing drivers and also new drivers being submitted,
although none of them modifies its DAI ops structure. The later is not
surprising since existing drivers are often used as templates for new drivers.
So this patch just constifies all existing snd_soc_dai_ops structs to eliminate
the issue altogether.
The patch was generated with the following coccinelle semantic patch:
// <smpl>
@@
identifier ops;
@@
-struct snd_soc_dai_ops ops =
+const struct snd_soc_dai_ops ops =
{ ... };
// </smpl>

The WM5100 includes an advanced, low power, accessory detect subsystem
capable of detecting both accessory presence and button presses while
the device is in an ultra low power mode. Implement initial support for
this.

The WM5100 is a highly integrated low power audio subsystem with advanced
digital signal processing capabilities including effects, speech clarity
enhancement and active noise cancellation. This initial driver provides
support for basic audio paths, further patches will provide more
complete functionality.
