[i2c] [patch 2.6.27-rc3] tps65010: vibrator hookup to gpiolib

From: Marek Vasut <marek.vasut at gmail.com>

All the tps6501{0,1,2,3,4} chips have a signal for hooking up with
a vibrator (for non-auditory cell phone "ring") ... expose that as
one more (output-only) GPIO.

[ dbrownell at users.sourceforge.net: comments; list tps65014 too ]
