Say yes here if you have TWL4030 family chip on your board.
This core driver provides register access and IRQ handling
facilities, and registers devices for the various functions
so that function-specific drivers can bind to them.
These multi-function chips are found on many OMAP2 and OMAP3
boards, providing power management, RTC, GPIO, keypad, a
high speed USB OTG transceiver, an audio codec (on most
versions) and many other features.
