This patch serie aims at integration of the Mitac Mio A701 smartphone's sound
system into alsa sound system.

It should be noted that this serie applies upon asoc-v2-dev tree, commit id
e02f9491e1e6d9720e0caffdb8e5edc259f41946, and should not hit alsa tree before
2.6.27, because A701 official support will be included at that version through
arm tree (perhaps even 2.6.28, depending on Russell's time).

Happy review.

This machine driver enables sound functions on Mitac mio
a701 smartphone. Build upon ASoC v1, it handles :
 - rear speaker
 - front speaker
 - microphone
 - GSM

A global "Mio Mode" switch is not yet provided to cope with
audio path setup. As balance on audio chip line is no more
assured, an incorrect setup can produce a lot of heat and
even fry the battery behind the wm9713 and the speaker
amplificator.

It doesn't cope with :
 - headset jack
 - mio master mode
 - master volume control

This driver is backported from ASoc v2, and amputated from
scenario setups and master volume control.
