2017-10-23extcon: Split out extcon header file for consumer and provider deviceChanwoo Choi1-0/+142
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 Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Acked-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk> Acked-by: Chen-Yu Tsai <wens@csie.org> Acked-by: Charles Keepax <ckeepax@opensource.cirrus.com> Acked-by: Lee Jones <lee.jones@linaro.org> Acked-by: Felipe Balbi <felipe.balbi@linux.intel.com> Acked-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Acked-by: Kishon Vijay Abraham I <kishon@ti.com>
