* extcon: Redefine the unique id of supported external connectors without ↵Chanwoo Choi2015-06-1312-28/+28
| | | | | | | | | | | | | | | '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: Remove optional print_name() function pointer of extcon_devChanwoo Choi2015-05-291-8/+0
| | | | | | | | | | | This patch removes the optional print_name() function pointer included in 'struct extcon_dev' because the extcon must maintain the consistent name of extcon device on sysfs instead of inconsistent name. After merged patch[1], extcon can maintain the consistent name of extcon device without any hard-coded device name.

* extcon: Update the prototype of extcon_register_notifier() with enum extconChanwoo Choi2015-05-221-43/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

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>

| * extcon: max77693: Fix cable name of JIG_UART_ONKrzysztof Kozlowski2014-11-241-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When JIG was set to "boot on" mode, the UART connection did not work because it was assigned to Dock-Car cable (path: audio), not JIG-UART-ON cable. This was introduced in 39bf369e4ed3 ("extcon: max77693: Add support dock device and buttons") while adding dock features. Assign the JIG-UART-ON back to UART path.

| * extcon: Implement OF-based extcon lookup properlyTomasz Figa2014-11-241-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Platform bus is not the only way to have extcon devices, so current implementation of of_extcon_get_extcon_dev() is broken. Also using parent device node only to get device name is quite ugly. This patch reimplements of_extcon_get_extcon_dev() to do exactly the same as extcon_get_extcon_dev() but instead of comparing names, compare node pointers.

* extcon: max77693: Fix a bug occured at changing ADC debounce time.Jonghwa Lee2014-09-221-4/+8
| | | | | | | | | | | When it writes some value other than 0 to BTLDset and JIGset, muic device will be reset automatically. And it happens during updating ADC debounce time, because it shares same register. To update ADC debounce time without reset, set value only to ADCDbset and 0 to BTLDset and JIGset.

* extcon: rt8973a: Add Richtek RT8973A extcon driverChanwoo Choi2014-09-224-0/+956
| | | | | | | | | | | | | This patch add support for Richtek RT8973A which is Micro USB Switch OVP and i2c interface. The RT8973A is a USB port accessory detector and switch that is optimized to protect low voltage system from abnormal high input voltage (up to 28V) and supports high speed USB operation. Also, RT8973A support 'auto-configuration' mode. If auto-configuration mode is enabled, RT8973A would control internal h/w patch for USB D-/D+ switching.
