* extcon: Use the extcon_set_state_sync() instead of deprecated functionsChanwoo Choi2016-09-131-1/+1
| | | | | | | | | | | | | | | | | This patch alters the renamed extcon API to set the state of the external connectors instead of deprecated extcon_set_cable_state_(). Because the patch[1] modifies the function name to maintain the function naming pattern. - extcon_set_cable_state_() -> extcon_set_state_sync() - extcon_get_cable_state_() -> extcon_get_state() [1] https://lkml.org/lkml/2016/8/4/729 - extcon: Rename the extcon_set/get_state() to maintain the function naming pattern Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Acked-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Acked-by: Roger Quadros <rogerq@ti.com>

* extcon: Modify the id and name of external connectorChanwoo Choi2015-10-161-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch modifies the id and name of external connector with the additional prefix to clarify both attribute and meaning of external connector as following: - EXTCON_CHG_* mean the charger connector. - EXTCON_JACK_* mean the jack connector. - EXTCON_DISP_* mean the display port connector. Following table show the new name of external connector with old name: -------------------------------------------------- Old extcon name | New extcon name | -------------------------------------------------- EXTCON_TA | EXTCON_CHG_USB_DCP | EXTCON_CHARGE_DOWNSTREAM| EXTCON_CHG_USB_CDP | EXTCON_FAST_CHARGER | EXTCON_CHG_USB_FAST | EXTCON_SLOW_CHARGER | EXTCON_CHG_USB_SLOW | -------------------------------------------------- EXTCON_MICROPHONE | EXTCON_JACK_MICROPHONE | EXTCON_HEADPHONE | EXTCON_JACK_HEADPHONE | EXTCON_LINE_IN | EXTCON_JACK_LINE_IN | EXTCON_LINE_OUT | EXTCON_JACK_LINE_OUT | EXTCON_VIDEO_IN | EXTCON_JACK_VIDEO_IN | EXTCON_VIDEO_OUT | EXTCON_JACK_VIDEO_OUT | EXTCON_SPDIF_IN | EXTCON_JACK_SPDIF_IN | EXTCON_SPDIF_OUT | EXTCON_JACK_SPDIF_OUT | -------------------------------------------------- EXTCON_HMDI | EXTCON_DISP_HDMI | EXTCON_MHL | EXTCON_DISP_MHL | EXTCON_DVI | EXTCON_DISP_DVI | EXTCON_VGA | EXTCON_DISP_VGA | -------------------------------------------------- And, when altering the name of USB charger connector, EXTCON refers to the "Battery Charging v1.2 Spec and Adopters Agreement"[1] to use the standard name of USB charging port as following. Following name of USB charging port are already used in power_supply subsystem. We chan check it on patch[2]. - EXTCON_CHG_USB_SDP /* Standard Downstream Port */ - EXTCON_CHG_USB_DCP /* Dedicated Charging Port */ - EXTCON_CHG_USB_CDP /* Charging Downstream Port */ - EXTCON_CHG_USB_ACA /* Accessory Charger Adapter */ [1] www.usb.org/developers/docs/devclass_docs/BCv1.2_070312.zip [2] commit 85efc8a18ced ("power_supply: Add types for USB chargers") Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> [ckeepax: For the Arizona changes] Acked-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Reviewed-by: Roger Quadros <rogerq@ti.com>
* extcon: axp288: Convert to using managed resourcesVaishali Thakkar2015-09-291-18/+5
| | | | | | | | | | | | | | Use resource managed functions devm_usb_get_phy and devm_gpio_request to make error path simpler. To be compatible the change, various gotos are replaced with direct returns and unnecessary label gpio_req_failed is dropped. Also, remove function axp288_extcon_remove as it is now redundant.

* extcon: Redefine the unique id of supported external connectors without ↵Chanwoo Choi2015-06-121-2/+2
| | | | | | | | | | | | | | | 'enum extcon' type 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 Fixes: 2a9de9c0f08d ("extcon: Use the unique id for external connector instead of string") Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* extcon: Use the unique id for external connector instead of stringChanwoo Choi2015-05-221-14/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) Cc: Arnd Bergmann <arnd@arndb.de> Cc: Felipe Balbi <balbi@ti.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Acked-by: Roger Quadros <rogerq@ti.com> Acked-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Acked-by: Ramakrishna Pallala <ramakrishna.pallala@intel.com> Reviewed-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> [arnd: Report the build break about drivers/usb/phy/phy-tahvo.c after using the unique id for external connector insteadf of string] Reported-by: Arnd Bergmann <arnd@arndb.de> [dan.carpenter: Report the build warning of extcon_{set|get}_cable_state_()] Reported-by: Dan Carpenter <dan.carpenter@oracle.com>
