i2c/tps65010: Vibrator hookup to gpiolib
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@users.sourceforge.net: comments; list tps65014 too ] Signed-off-by: Marek Vasut <marek.vasut@gmail.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
