The WM8974 is a low power, high quality mono CODEC designed for portable applications such as digital still cameras or digital voice recorders. This driver was originally written by Graeme Gregory and Liam Girdwood and has since been maintained by myself with some updates contributed by Brett Saunders and Javier Martin.
