From ab37813f4093a5f59cb8e083cde277289dc72ed3 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Wed, 9 May 2012 07:40:40 +1000 Subject: twl4030_charger: Allow charger to control the regulator that feeds it The charger needs usb3v1 to be running, so add a new consumer to keep it running. This allows the charger to draw current even when the USB driver has powered down.
