[PATCH v2 0/5] MFD/ASoC: Add support for Intel Bay Trail boards with WM5102 codec

Hi All,

Here is v2 of my series to add support for Intel Bay Trail based devices
which use a WM5102 codec for audio output/input. This was developed and
tested on a Lenovo Yoga Tablet 1051L.

The biggest difference from v1 is that, based on all the discussions about
the jack-detect stuff, I've decided to split this into 2 series.
One series adding the basic support for this setup, which is this series.

And a second series which reworks the extcon driver into an arizona-jackdet
library and then modifies the codec drivers to use that directly, replacing
the old separate extcon child-device and extcon-driver.

The are 2 reasons for the split:

1. With the new jack-det rework, the series really address 2 separate
(but related) enhancements.

2. I expect this series to be ready for merging, while the jack-det stuff
likely will need a couple more revisions.

Other then the split there are some minor changes addressing various review
comments, see the individual patch changelogs.

The MFD and ASoC parts can be merged independent from each-other (both must
be merged to get working sound on these boards, but that is only a runtime
dependency and a part missing won't have any bad side-effects). Or the
entire series could be merged through the MFD tree if people prefer that.
