Mark Brown 8f103167fe ASoC: Map microphones on Littlemill 
Littlemill has one analogue microphone on the board (connected to IN1LN)
and an array of four DMICs connected to both DMICDAT lines. The biases
can be selected by jumpers but pick the default jumper fit.

Mark Brown f2e2026c98 ASoC: Add WM8958 based headset detection on Littlemill 
The board supports CODECs that won't work with this but the CODEC driver
will check to see if it's running on the right chip for us.

Mark Brown 0a590b1de2 ASoC: Add basic 1277-EV1 Littlemill audio driver 
The Littlemill audio card supports a number of pluggable miniboards,
normally for the WM8994 family of devices. As all these devices look
mostly the same from an external configuration point of view and are
runtime enumerable we can write a standard machine driver which will
work out of the box with any of them. Start doing that with the bare
bones of a driver, only supporting AIF1.

Future patches will flesh this out to be more fully featured.
