Cirrus Logic Family of ADCs 

Merge series from Paul Handrigan <paulha@opensource.cirrus.com>:

This patchset provides ASoC support for the latest family
of Cirrus Logic multichannel, high performance audio ADCs.
The devices that are supported are CS5302 (2 channel ADC),
CS5304 (4 channel ADC), and CS5308 (8 channel ADC).
