extcon: Introduce EXTCON_PROP_DISP_HPD property

2016-09-13T01:08:47Z

EXTCON_PROP_DISP_HPD is need by display port, if the system has no hpd interrupt, this property can be used. - HPD (Hot Plug Detect) send the signal whether display device is on or off to source device.

extcon: Add new EXTCON_CHG_WPT for Wireless Power Transfer device

2016-09-10T11:18:57Z

This patchs add the new EXTCON_CHG_WPT for Wireless Power Transfer[1]. The Wireless Power Transfer is the transmission of electronical energy from a power source. The EXTCON_CHG_WPT has the EXTCON_TYPE_CHG. [1] https://en.wikipedia.org/wiki/Wireless_power_transfer Signed-off-by: Chanwoo Choi

extcon: Add new EXTCON_DISP_HMD for Head-mounted Display device

2016-09-10T11:18:56Z

This patch adds the new EXTCON_DISP_HMD id for Head-mounted Display[1] device. The HMD device is usually for USB connector type So, the HMD connector has the two extcon types of both EXTCON_TYPE_DISP and EXTCON_TYPE_USB.

extcon: Add EXTCON_DISP_DP and the property for USB Type-C

2016-09-10T11:18:55Z

Add EXTCON_DISP_DP for the Display external connector. For Type-C connector the DisplayPort can work as an Alternate Mode(VESA DisplayPort Alt Mode on USB Type-C Standard). The Type-C support both normal and flipped orientation, so add a property to extcon.

extcon: Add the synchronization extcon APIs to support the notification

2016-09-10T11:18:54Z

This patch adds the synchronization extcon APIs to support the notifications for both state and property. When extcon_*_sync() functions is called, the extcon informs the information from extcon provider to extcon client. The extcon driver may need to change the both state and multiple properties at the same time. After setting the data of a external connector, the extcon send the notification to client driver with the extcon_*_sync(). The list of new extcon APIs as following: - extcon_sync() : Send the notification for each external connector to synchronize the information between extcon provider driver and extcon client driver. - extcon_set_state_sync() : Set the state of external connector with noti. - extcon_set_property_sync() : Set the property of external connector with noti. For example, case 1, change the state of external connector and synchronized the data. extcon_set_state_sync(edev, EXTCON_USB, 1); case 2, change both the state and property of external connector and synchronized the data. extcon_set_state(edev, EXTCON_USB, 1); extcon_set_property(edev, EXTCON_USB, EXTCON_PROP_USB_VBUS 1); extcon_sync(edev, EXTCON_USB); case 3, change the property of external connector and synchronized the data. extcon_set_property(edev, EXTCON_USB, EXTCON_PROP_USB_VBUS, 0); extcon_sync(edev, EXTCON_USB); case 4, change the property of external connector and synchronized the data. extcon_set_property_sync(edev, EXTCON_USB, EXTCON_PROP_USB_VBUS, 0); Signed-off-by: Chanwoo Choi Tested-by: Chris Zhong Tested-by: Guenter Roeck Reviewed-by: Guenter Roeck

extcon: Rename the extcon_set/get_state() to maintain the function naming pattern

2016-09-10T11:18:53Z

This patch just renames the existing extcon_get/set_cable_state_() as following because of maintaining the function naming pattern like as extcon APIs for property. - extcon_set_cable_state_() -> extcon_set_state() - extcon_get_cable_state_() -> extcon_get_state() But, this patch remains the old extcon_set/get_cable_state_() functions to prevent the build break. After altering new APIs, remove the old APIs. Signed-off-by: Chanwoo Choi Tested-by: Chris Zhong Tested-by: Guenter Roeck Reviewed-by: Guenter Roeck

extcon: Add the support for the capability of each property

2016-09-10T11:18:52Z

This patch adds the support of the property capability setting. This function decides the supported properties of each external connector on extcon provider driver. Ths list of new extcon APIs to get/set the capability of property as following: - int extcon_get_property_capability(struct extcon_dev *edev, unsigned int id, unsigned int prop); - int extcon_set_property_capability(struct extcon_dev *edev, unsigned int id, unsigned int prop); Signed-off-by: Chanwoo Choi Tested-by: Chris Zhong Tested-by: Guenter Roeck Reviewed-by: Guenter Roeck
