2016-09-13extcon: Use the extcon_set_state_sync() instead of deprecated functionsChanwoo Choi
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>
2016-08-08extcon: arizona: Remove the usage of extcon_update_state()Chanwoo Choi
This patch remvoes the usage of extcon_update_state() because the extcon_update_state() use directly the bit masking calculation to change the state of external connector without the unique id of external connector. It makes the code diffcult to read it. So, this patch uses the extcon_set_cable_state_() instead.

Some Arizona devices have the option to use the GPIO5 pin as a second jack detection pin. This patch adds device bindings to specify to the driver that it should use this pin.

2015-09-22extcon: arizona: Don't disable debounce for inverted jacksCharles Keepax
Whilst the jack is connected we disable the jack detection debounce to ensure as quick as possible a detection of jack removal. However, it is only safe to disable the jack debounce whilst the jack is connected if using the micd clamp or the jack is not inverted.

This patch simplifies the symantics to 2 for 2 measurements, 4 for 4 measurements and any other value for the default.

'enum extcon' type This patch just redefine the unique id of supported external connectors without 'enum extcon' type.

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>
2015-05-22extcon: Use the unique id for external connector instead of stringChanwoo Choi
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>

2014-07-23extcon: arizona: Get MICVDD against extcon deviceCharles Keepax
Previously we would do a regulator get against the main Arizona device to obtain the MICVDD regulator. Arizona is an MFD device and normally MICVDD will be supplied by one of its children (the arizona-micsupp regulator). As devres destruction for the MFD device will run after all its children have been destroyed, the regulator will be destroyed before devres calls regulator_put. This causes a warning from both the destruction of the child node, as the regulator is still open, and from the put of the regulator as the regulator device has already been destroyed. A simple fix here is to get the regulator against the extcon device itself such that devres runs when the child is destroyed. This has the additional benefit that if for some reason the extcon driver is unloaded the regulator reference won't hang around until the MFD is unloaded.

2014-04-24extcon: arizona: Use devm_extcon_dev_register()Sangjung Woo
Use the resource-managed extcon device register function (i.e. devm_extcon_dev_register()) instead of extcon_dev_register(). If extcon device is attached with this function, that extcon device is automatically unregistered on driver detach. That reduces tiresome managing code.

2014-02-20ASoC: dapm: Add locking to snd_soc_dapm_xxxx_pin functionsCharles Keepax
The snd_soc_dapm_xxxx_pin all require the dapm_mutex to be held when they are called as they edit the dirty list, however very few of the callers do so. This patch adds unlocked versions of all the functions replacing the existing implementations with one that holds the lock internally. We also fix up the places where the lock was actually held on the caller side.
