+ The Wolfson Microelectronics 1190-EV1 is a WM835x based PMIC
+ and audio daughtercard for the Samsung SMDK6410 reference
+ platform. Enabling this option will build support for this
+ module into the kernel. The presence of the module will be
+ detected at runtime so the the resulting kernel can be used
+ with or without the 1190-EV1 fitted.
