	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>
2016-09-13	extcon: Use the extcon_set_state_sync() instead of deprecated functions	Chanwoo Choi
	This patch alters the renamed extcon API to set the state of the external connectors instead of deprecated extcon_set_cable_state_(). Because the patch[1] modifies the function name to maintain the function naming pattern. - extcon_set_cable_state_() -> extcon_set_state_sync() - extcon_get_cable_state_() -> extcon_get_state() [1] https://lkml.org/lkml/2016/8/4/729 - extcon: Rename the extcon_set/get_state() to maintain the function naming pattern Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Acked-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Acked-by: Roger Quadros <rogerq@ti.com>
2015-12-21	extcon: add Maxim MAX3355 driver	Sergei Shtylyov
	Maxim Integrated MAX3355E chip integrates a charge pump and comparators to enable a system with an integrated USB OTG dual-role transceiver to function as an USB OTG dual-role device. In addition to sensing/controlling Vbus, the chip also passes thru the ID signal from the USB OTG connector. On some Renesas boards, this signal is just fed into the SoC thru a GPIO pin -- there's no real OTG controller, only host and gadget USB controllers sharing the same USB bus; however, we'd like to allow host or gadget drivers to be loaded depending on the cable type, hence the need for the MAX3355 extcon driver. The Vbus status signals are also wired to GPIOs (however, we aren't currently interested in them), the OFFVBUS# signal is controlled by the host controllers, there's also the SHDN# signal wired to a GPIO, it should be driven high for the normal operation.
