    extcon: Split out extcon header file for consumer and provider device · 176aa360
    Chanwoo Choi authored
    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
