1142           systems.  This option enables core support for the WM8350 with
1143           I2C as the control interface.  Additional options must be
1144           selected to enable support for the functionality of the chip.

1153           The WM8994 is a highly integrated hi-fi CODEC designed for
1154           smartphone applicatiosn.  As well as audio functionality it
1155           has on board GPIO and regulator functionality which is
1156           supported via the relevant subsystems.  This driver provides
1157           core support for the WM8994, in order to use the actual
1158           functionaltiy of the device other drivers must be enabled.
