git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator Pull regulator updates from Mark Brown: "The biggest changes in the core this time around have been some refactorings that move us towards being able to drop the list of regulators maintained by the core and instead just use the driver model list maintained for the class devices for regulators which will make the code smaller and avoid some potential bugs. Otherwise another fairly quiet release for the regulator API, highlights include: - a new API for setting voltages based on a minimum, target, maximum triplet - support for continuous voltage ranges rather than tables of explicit steps in the PWM regulator, requiring less explicit configuration - new driver support for Dialog DA9215, Maxim 77843, Mediatek MT6311 and Qualcomm RPM" * tag 'regulator-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (70 commits) regulator: mt6311: fix platform_no_drv_owner.cocci warnings regulator: ltc3589: Remove unnecessary MODULE_ALIAS() regulator: ad5398: Remove unnecessary MODULE_ALIAS() regulator: pfuze100: Remove unnecessary MODULE_ALIAS() regulator: core: use debug level print in regulator_check_drms regulator: lp872x: handle error case regulator: lp872x: use the private data instead of updating I2C device platform data regulator: isl9305: Export OF module alias information regulators: max77693: register driver earlier to avoid deferred probe regulator: qcom_smd: Set n_voltages for pm8941_lnldo regulator: core: Use IS_ERR_OR_NULL() regulator: core: Define regulator_set_voltage_triplet() regulator: Regulator driver for the Qualcomm RPM regulator: pbias: Fix broken pbias disable functionality regulator: core: Spelling fix regulator: core: Use class device list for regulator_list in late init regulator: core: Move more deallocation into class unregister regulator: core: Reduce rdev locking region when releasing regulator Input: Remove the max77843 haptic driver Input: max77693: Add support for Maxim 77843 ...

2015-07-31extcon: Fix hang and extcon_get/set_cable_state().Roger Quadros
Users of find_cable_index_by_name() will cause a kernel hang as the while loop counter is never incremented and end condition is never reached. extcon_get_cable_state() and extcon_set_cable_state() are broken because they use cable index instead of cable id. This causes the first cable state (cable.0) to be always invalid in sysfs or extcon_get_cable_state() users. Introduce a new function find_cable_id_by_name() that fixes both of the above issues.

2015-05-22extcon: Update the prototype of extcon_register_notifier() with enum extconChanwoo Choi
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().

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>

2015-04-27extcon: usb-gpio: register extcon device before IRQ registrationRobert Baldyga
