1515           The WM8350 is an integrated audio and power management
1516           subsystem with watchdog and RTC functionality for embedded
1517           systems.  This option enables core support for the WM8350 with
1518           I2C as the control interface.  Additional options must be

1528           The WM8994 is a highly integrated hi-fi CODEC designed for
1529           smartphone applications.  As well as audio functionality it
1530           has on board GPIO and regulator functionality which is
1531           supported via the relevant subsystems.  This driver provides
1532           core support for the WM8994, in order to use the actual
1533           functionaltiy of the device other drivers must be enabled.
