1752 bool "Wolfson Microelectronics WM8350 with I2C"
1757 The WM8350 is an integrated audio and power management
1758 subsystem with watchdog and RTC functionality for embedded
1759 systems. This option enables core support for the WM8350 with
1760 I2C as the control interface. Additional options must be
1761 selected to enable support for the functionality of the chip.
1764 tristate "Wolfson Microelectronics WM8994"
1770 The WM8994 is a highly integrated hi-fi CODEC designed for
1771 smartphone applications. As well as audio functionality it
1772 has on board GPIO and regulator functionality which is
1773 supported via the relevant subsystems. This driver provides
1774 core support for the WM8994, in order to use the actual
1775 functionaltiy of the device other drivers must be enabled.

1782 depends on AC97_BUS_NEW
1784 The WM9705, WM9712 and WM9713 is a highly integrated hi-fi CODEC
1785 designed for smartphone applications. As well as audio functionality
1786 it has on board GPIO and a touchscreen functionality which is
1787 supported via the relevant subsystems. This driver provides core
1788 support for the WM97xx, in order to use the actual functionaltiy of
1789 the device other drivers must be enabled.
