Please work in terms of the ALSA controls - it is much easier to provide
support when working through the exposed interfaces and direct register
writes may be overwritten by the driver, causing additional confusion.

To get the latest development code:

	git clone git://opensource.wolfsonmicro.com/linux-2.6-asoc
	cd linux-2.6-asoc

You can generate a diff from a tag to the latest development branch like

	git diff v2.6.26..origin/dev

(Linux releases are tagged in that format - 'git tag' will list the
known tags) specifying directories lets you filter what's included so:

	git diff v2.6.26..origin/dev sound include/sound

will only give you ALSA related changes.
