Subject: [PATCH 0/6] twl4030: Various fixes for charing-from-USB 

Following are a collection of patches that I've need using for a while
to make sure the charge-from-usb on my GTA04 works.
Hopefully I've included the right people in the recipient list :-)

The issues are:
 - charge the backup battery as well as the main battery
 - charge from a charger which ties ID to ground via a resistor
 - charge while device is suspended, or when no gadget module is
   loaded (i.e. when the USB side thinks the phy should be powered
   down).

Questions and comments more welcome.

Thanks,
NeilBrown

      twl4030-usb: Don't report EVENT_ID when there is VBUS.
      twl4030-usb: Don't power down phy when it is in-use by charger.
      twl4030_charger: Allow charger to control the regulator that feeds it.
      twl4030_charger: allow charging whenever VBUS is present.
      twl4030_charger: add backup-battery charging.
      twl4030_charger: Fix some typos
