extcon: Correct description to improve the readability

2017-08-16T00:27:55+00:00

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.

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

2017-04-04T02:22:42+00:00

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);

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

2017-01-09T01:04:11+00:00

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.

extcon: Add resource-managed functions to register extcon notifier

2016-06-27T12:03:23+00:00

This patch adds the resource-managed functions for register/unregister
the extcon notifier with the id of each external connector. This function
will make it easy to handle the extcon notifier.

- int devm_extcon_register_notifier(struct device *dev,
				struct extcon_dev *edev, unsigned int id,
				struct notifier_block *nb);
- void devm_extcon_unregister_notifier(struct device *dev,
				struct extcon_dev *edev, unsigned int id,
				struct notifier_block *nb);
