extcon: Add stubs for extcon_register_notifier_all() functions

2021-04-07T10:47:03Z

[ Upstream commit c9570d4a5efd04479b3cd09c39b571eb031d94f4 ] Add stubs for extcon_register_notifier_all() function for !CONFIG_EXTCON case. This is useful for compile testing and for drivers which use EXTCON but do not require it (therefore do not depend on CONFIG_EXTCON). Fixes: 815429b39d94 ("extcon: Add new extcon_register_notifier_all() to monitor all external connectors") Reported-by: kernel test robot Signed-off-by: Krzysztof Kozlowski Signed-off-by: Chanwoo Choi Signed-off-by: Sasha Levin

extcon: Use tab instead of space for indentation

2017-08-16T00:27:55Z

The extcon header file defines the functions which used the mismatched indentation and used the space on some case. So, this patch clean-up the indentation in order to improve the readbility. And this patch changes the return value of extcon_get_extcon_dev() because of maintaing the same value with extcon_get_edev_by_phandle(). Signed-off-by: Chanwoo Choi

extcon: Correct description to improve the readability

2017-08-16T00:27:55Z

The extcon files explains the detailed operation for functions and what is meaning of extcon structure. There are different explanation even if the same argument. So, it modifies the description for both functions and structures in order to improve the readability and guide the role of functions more well. Also, this patch fixes the mismatching license info as a GPL v2 and removes the inactive author information. Signed-off-by: Chanwoo Choi

extcon: Remove deprecated extcon_set/get_cable_state_()

2017-08-16T00:21:49Z

The commit 575c2b867ee0 ("extcon: Rename the extcon_set/get_state() to maintain the function naming pattern") renames the extcon function as following: But, the extcon just keeps the old API to prevent the build error. This patch removes the deprecatd extcon API. - extcon_get_cable_state_() -> extcon_get_state() - extcon_set_cable_state_() -> extcon_set_state_sync() Signed-off-by: Chanwoo Choi

extcon: Add new extcon_register_notifier_all() to monitor all external connectors

2017-04-04T02:22:42Z

The extcon core already provides the extcon_register_notifier() function in order to register the notifier block which is used to monitor the state change for the specific external connector such as EXTCON_USB, EXTCON_USB_HOST and so on. The extcon consumer uses the this function. The extcon consumer might need to monitor the all supported external connectors from the extcon device. In this case, The extcon consumer should have each notifier_block structure for each external connector. This patch adds the new extcon_register_notifier_all() function that extcon consumer is able to monitor the state change of all supported external connectors by using only one notifier_block structure. - List of new added functions: int extcon_register_notifier_all(struct extcon_dev *edev, struct notifier_block *nb); int extcon_unregister_notifier_all(struct extcon_dev *edev, struct notifier_block *nb); int devm_extcon_register_notifier_all(struct device *dev, struct extcon_dev *edev, struct notifier_block *nb); void devm_extcon_unregister_notifier_all(struct device *dev, struct extcon_dev *edev, struct notifier_block *nb); Suggested-by: Hans de Goede Signed-off-by: Chanwoo Choi Tested-by: Hans de Goede Acked-by: Hans de Goede

extcon: Add new EXTCON_CHG_USB_PD type for USB Power Delivery

2017-01-09T01:04:58Z

This patch adds the new EXTCON_CHG_USB_PD for USB PD (Power Delivery)[1]. The USB Power Delivery specification specifies that USB cable provides the increased power more than 7.5W to device with larger power demand. The EXTCON_CHG_USB_PD has the EXTCON_TYPE_CHG and EXTCON_TYPE_USB type. [1] https://en.wikipedia.org/wiki/USB#PD Signed-off-by: Chanwoo Choi

extcon: Add documentation for EXTCON_CHG_USB_SLOW/FAST

2017-01-09T01:04:12Z

Currently there are no documentation for EXTCON_CHG_USB_SLOW/FAST charger connector. These names don't mean much and no guide to tell users how to use it, thus try to add documentation to make them clear.

extcon: Move defintion of struct extcon_dev to driver/extcon directory

2017-01-09T01:04:11Z

This patch moves the 'struct extcon_dev' of extcon subsystem to driver/extcon/extcon.h header file because the struct extcon_dev have to be handled by extcon API to guarantee the consistency of strcut extcon_dev. If external drivers are able to touch the struct extcon_dev directly, it might cause the critical and unknown problem. Signed-off-by: Chanwoo Choi

extcon: Add documentation for EXTCON_CHG_USB_* and EXTCON_USB_*

2017-01-09T01:04:11Z

Current there is both "EXTCON_USB" and "EXTCON_CHG_USB_SDP" which both seem to suggest a standard downstream port. But there is no documentation describing how these relate. Thus add documentation to describe EXTCON_CHG_USB_SDP should always appear together with EXTCON_USB, and EXTCON_CHG_USB_ACA would normally appear with EXTCON_USB_HOST.
