In linux kernel since version 2.6.28 (release Date: 2008-12-24)  
Say yes here if you have TWL4030 / TWL6030 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.
