> 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
