mfd/extcon: max77693: Rename defines to allow inclusion with max77843

2015-07-16T20:39:30+00:00

Add MAX77693 prefix to some of the defines used in max77693 extcon
driver so the max77693-private.h can be included simultaneously with
max77843-private.h.

Additionally use BIT() macro in header.

drivers: max77693: Move state container to common header

2015-07-16T20:39:30+00:00

This prepares for merging some of the drivers between max77693 and
max77843 so the child MFD driver can be attached to any parent MFD main
driver.

Move the state container to common header file. Additionally add
consistent 'i2c' prefixes to its members (of 'struct i2c_client' type).

mfd/extcon: max77693: Remove unused extern declarations and max77693_dev members

2015-07-16T20:39:29+00:00

Clean up the max77693 private header file by removing:
1. Left-overs from previous way of interrupt handling (driver uses
   regmap_irq_chip).
2. Unused members of struct 'max77693_dev' related to interrupts in
   extcon driver.

extcon: Redefine the unique id of supported external connectors without 'enum extcon' type

2015-06-13T00:01:42+00:00

This patch just redefine the unique id of supported external connectors without
'enum extcon' type. Because unique id would be used on devictree file(*.dts) to
indicate the specific external connectors like key number of input framework.
So, I have the plan to move this definitions to following header file which
includes the unique id of supported external connectors.
- include/dt-bindings/extcon/extcon.h

extcon: Use the unique id for external connector instead of string

2015-05-22T09:58:44+00:00

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)

extcon: Remove the optional name of extcon device

2015-05-19T07:39:06+00:00

This patch removes the optional name of extcon device. Instead,
extcon_dev_register() set the device name as 'extcon[number]' naming pattern.
- /sys/class/extcon/[hardcoded device name] -> /sys/class/extcon/extcon[number]

extcon: Alter MHL-TA cable name to TA cable name

2015-05-19T07:39:06+00:00

This patch alters the MHL-TA cable name to TA cable name because MHL-TA is not
standard name. The MHL-TA is MHL cable with charger cable (TA or USB). So, this
patch use the TA cable instead of MHL-TA to inform the charger cable state.
- MHL-TA -> TA

extcon: Unify the dock device names on max8997/77693

This patch change the name of various dock devices as 'DOCK' because the name of
various dock devices have not the standard naming rules. The name of dock devices
include the differenct word but it is ambiguous and never important information
on user-space aspect. This patch unifies the name of dock devices as following:
- Dock-Smart   -->|--> DOCK
