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);

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.

Previously, extcon consumer driver used the extcon_register_interest()
to register the notifier chain and then to receive the notifier event
when external connector's state is changed. When registering the notifier chain
for specific external connector with extcon_register_interest(), it used the
the string name of external connector directly. There are potential problem
because of unclear, non-standard and inconsequent cable name. Namely,
it is not appropriate method to identify each external connector.
So, this patch modify the prototype of extcon_register_notifier() by using
the 'enum extcon' which are the unique id for each external connector
instead of unclear string method.
- Previously, the extcon consumer driver used the extcon_register_interest()
with 'cable_name' to point out the specific external connector. Also. it used
the un-needed structure (struct extcon_specific_cable_nb).
: int extcon_register_interest(struct extcon_specific_cable_nb *obj,
const char *extcon_name, const char *cable_name,
struct notifier_block *nb)
- Newly, the updated extcon_register_notifier() would definitely support
the same feature to detech the changed state of external connector without
any specific structure (struct extcon_specific_cable_nb).
: int extcon_register_notifier(struct extcon_dev *edev, enum extcon id,
struct notifier_block *nb)
This patch support the both extcon_register_interest() and new extcon_register_
notifier(). But the extcon_{register|unregister}_interest() will be deprecated
because extcon core would support the notifier event for extcon consumer driver
with only updated extcon_register_notifier() and 'extcon_specific_cable_nb'
will be removed if there are no extcon consumer driver with legacy
extcon_{register|unregister}_interest().

This patch uses the unique id to identify the type of external connector instead
of string name. The string name have the many potential issues. So, this patch
defines the 'extcon' enumeration which includes all supported external connector
on EXTCON subsystem. If new external connector is necessary, the unique id of
new connector have to be added in 'extcon' enumeration. There are current
supported external connector in 'enum extcon' as following:
enum extcon {
EXTCON_NONE = 0x0,
/* USB external connector */
EXTCON_USB = 0x1,
EXTCON_USB_HOST = 0x2,
/* Charger external connector */
EXTCON_TA = 0x10,
EXTCON_FAST_CHARGER = 0x11,
EXTCON_SLOW_CHARGER = 0x12,
EXTCON_CHARGE_DOWNSTREAM = 0x13,
/* Audio and video external connector */
EXTCON_LINE_IN = 0x20,
EXTCON_LINE_OUT = 0x21,
EXTCON_MICROPHONE = 0x22,
EXTCON_HEADPHONE = 0x23,
EXTCON_HDMI = 0x30,
EXTCON_MHL = 0x31,
EXTCON_DVI = 0x32,
EXTCON_VGA = 0x33,
EXTCON_SPDIF_IN = 0x34,
EXTCON_SPDIF_OUT = 0x35,
EXTCON_VIDEO_IN = 0x36,
EXTCON_VIDEO_OUT = 0x37,
/* Miscellaneous external connector */
EXTCON_DOCK = 0x50,
EXTCON_JIG = 0x51,
EXTCON_MECHANICAL = 0x52,
EXTCON_END,
};
For example in extcon-arizona.c:
To use unique id removes the potential issue about handling
the inconsistent name of external connector with string.
- Previously, use the string to register the type of arizona jack connector
static const char *arizona_cable[] = {
"Mechanical",
"Microphone",
"Headphone",
"Line-out",
};
- Newly, use the unique id to register the type of arizona jack connector
static const enum extcon arizona_cable[] = {
EXTCON_MECHANICAL,
EXTCON_MICROPHONE,
EXTCON_HEADPHONE,
EXTCON_LINE_OUT,
EXTCON_NONE,
};
And this patch modify the prototype of extcon_{get|set}_cable_state_() which
uses the 'enum extcon id' instead of 'cable_index'. Because although one more
extcon drivers support USB cable, each extcon driver might has the differnt
'cable_index' for USB cable. All extcon drivers can use the unique id number
for same external connector with modified extcon_{get|set}_cable_state_().
- Previously, use 'cable_index' on these functions:
extcon_get_cable_state_(struct extcon_dev*, int cable_index)
extcon_set_cable_state_(struct extcon_dev*, int cable_index, bool state)
-Newly, use 'enum extcon id' on these functions:

extcon_set_cable_state_(struct extcon_dev*, enum extcon id, bool state)
