The first patch is a refactoring to make the extcon side easier.

* | | extcon: arizona: Simplify HPDET based identificationMark Brown2013-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than measuring both HP channels we can simply directly measure the microphone impedance and then rely on MICDET for final confirmation of the presence of a suitable microphone. This improves the overall performance of the identification process. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* | ASoC: arizona: Fix interaction between headphone outputs and identificationMark Brown2013-03-26
|/ | | | | | | | | | | | | | 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.

Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset." Far amount of annoying but largely trivial conflicts.

Once the generic clock API is widely available this code will be moved over to use that.
