This patch removes the usage of extcon_set_state() because it uses the bit
masking to change the state of external connectors. The extcon framework
should handle the state by extcon_set/get_cable_state_() with extcon id.

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

External connector devices that decides connection information based on
ADC values may use adc-jack device driver. The user simply needs to
provide a table of adc range and connection states. Then, extcon
framework will automatically notify others.
Changes in V1:
added Lars-Peter Clausen suggested changes:
Using macros to get rid of boiler plate code such as devm_kzalloc
and module_platform_driver.Other changes suggested are related to
coding guidelines.
Changes in V2:
Removed some unnecessary checks and changed the way we are un-regitering
extcon and freeing the irq while removing.
Changes in V3:
Renamed the files to comply with extcon naming.
Changes in V4:
Added the cancel_work_sync during removing of driver.
Changes in V5:
Added the dependency of IIO in Kconfig.
Changes in V6:
Some nitpicks related to naming.
Changes in this version:
