extcon: return error code on failure

2017-01-19T19:18:03Z

commit 5b11ebedd6a8bb4271b796e498cd15c0fe1133b6 upstream. Function get_zeroed_page() returns a NULL pointer if there is no enough memory. In function extcon_sync(), it returns 0 if the call to get_zeroed_page() fails. The return value 0 indicates success in the context, which is incosistent with the execution status. This patch fixes the bug by returning -ENOMEM.

extcon: qcom-spmi-misc: Sync the extcon state on interrupt

2016-10-26T07:04:29Z

The driver was changed after submission to use the new style APIs like extcon_set_state(). Unfortunately, that only sets the state, and doesn't notify any consumers that the cable state has changed. Use extcon_set_state_sync() here instead so that we notify cable consumers of the state change. This fixes USB host-device role switching on the db8074 platform.

extcon: Add support for qcom SPMI PMIC USB id detection hardware

2016-09-13T02:26:26Z

Some Qualcomm PMICs have a misc device that performs USB id pin detection via an interrupt. When the interrupt triggers, we should read the interrupt line to see if it has gone high or low. If the interrupt is low then the ID pin is grounded, and if the interrupt is high then the ID pin is being held high.

extcon: Use the extcon_set_state_sync() instead of deprecated functions

2016-09-13T02:26:26Z

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 Acked-by: Charles Keepax Acked-by: Roger Quadros

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.
