Chanwoo Choi 176aa36012 extcon: Split out extcon header file for consumer and provider device
The extcon has two type of extcon devices as following.
- 'extcon provider deivce' adds new extcon device and detect the
   state/properties of external connector. Also, it notifies the
   state/properties to the extcon consumer device.
- 'extcon consumer device' gets the change state/properties
   from extcon provider device.
Prior to that, include/linux/extcon.h contains all exported API for
both provider and consumer device driver. To clarify the meaning of
header file and to remove the wrong use-case on consumer device,
this patch separates into extcon.h and extcon-provider.h.

[Description for include/linux/{extcon.h|extcon-provider.h}]
- extcon.h includes the extcon API and data structure for extcon consumer
  device driver. This header file contains the following APIs:
  : Register/unregister the notifier to catch the change of extcon device
  : Get the extcon device instance
  : Get the extcon device name
  : Get the state of each external connector
  : Get the property value of each external connector
  : Get the property capability of each external connector

- extcon-provider.h includes the extcon API and data structure for extcon
  provider device driver. This header file contains the following APIs:
  : Include 'include/linux/extcon.h'
  : Allocate the memory for extcon device instance
  : Register/unregister extcon device
  : Set the state of each external connector
  : Set the property value of each external connector
  : Set the property capability of each external connector

Raviteja Garimella 787f24543c phy: phy-bcm-ns2-usbdrd: Broadcom USB DRD PHY driver for Northstar2
This is driver for USB DRD PHY used in Broadcom's Northstar2
SoC. The phy can be configured to be in Device mode or Host
mode based on the type of cable connected to the port. The
driver registers to  extcon framework to get appropriate
connect events for Host/Device cables connect/disconnect
states based on VBUS and ID interrupts.
