tate() function to check charger state.
- Remove the mutex lock in usb_charger_set_cur_limit_by_type() function
in case will be issued in atomic context.
Baolin Wang (4):
usb: gadget: Introduce the usb charger framework
usb: gadget: Support for the usb charger framework
usb: gadget: Integr
For supporting the usb charger, it adds the usb_charger_init() and
usb_charger_exit() functions for usb charger initialization and exit.
It will report to the usb charger when the gadget state is changed,
then the usb charger can do the power things.

When the usb gadget supporting for usb charger is ready, the usb charger
can implement the usb_charger_plug_by_gadget() function, usb_charger_exit()
function and dev_to_uchger() function by getting 'struct usb_charger' from
'struct gadget'.

usb gadget state.
This patch doesn't yet integrate with the gadget code, so some functions
which rely on the 'gadget' are not completed, that will be implemented
in the following patches.
