+ Pin multiplexing support for DAVINCI boards. If your bootloader
+ sets the multiplexing correctly, say N. Otherwise, or if unsure,
+ say Y.

+ help
+ Makes the multiplexing functions print out a lot of debug info.
+ This is useful if you want to find out the correct values of the
+ multiplexing registers.

+ help
+ Choose Y here to warn whenever driver initialization logic needs
+ to change the pin multiplexing setup. When there are no warnings
+ printed, it's safe to deselect DAVINCI_MUX for your product.
