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
