Subject: [patch 2.6.28-rc6 2/3] mfd: twl4030: cleanup symbols and OMAP dependency

From: David Brownell <dbrownell@...rs.sourceforge.net>

Finish removing dependency of TWL driver stack on platform-specific
IRQ definitions ... and remove the build dependency on OMAP.

This lets the TWL4030 code be included in test builds for most
platforms, and will make it easier for non-OMAP folk to update
most of this code for new APIs etc.

Relies on patch #1 to hand this data to drivers explicitly,
rather than through global #defines.  Build tested only on
X86_64 and ARM/OMAP.

 	  Say yes here if you have TWL4030 family chip on your board.
 	  This core driver provides register access and IRQ handling
