2015-03-07extcon: Rename extcon core driverChanwoo Choi1-1/+1
This patch renames the extcon core driver from extcon-class.c to extcon.c because '-class' postfix is not necessary. Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
2015-02-24extcon: max77843: Add max77843 MUIC driverJaewon Kim1-0/+1

2015-02-24extcon: usb-gpio: Introduce gpio usb extcon driverRoger Quadros1-0/+1
This driver observes the USB ID pin connected over a GPIO and updates the USB cable extcon states accordingly. The existing GPIO extcon driver is not suitable for this purpose as it needs to be taught to understand USB cable states and it can't handle more than one cable per instance. For the USB case we need to handle 2 cable states. 1) USB (attach/detach) 2) USB-HOST (attach/detach) This driver can be easily updated in the future to handle VBUS events in case it happens to be available on GPIO for any platform.

2014-09-22extcon: rt8973a: Add Richtek RT8973A extcon driverChanwoo Choi1-0/+1
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.

2012-09-05extcon: adc_jack: adc-jack driver to support 3.5 pi or simliar devicesanish kumar1-0/+1
External connector devices that decides connection information based on ADC values may use adc-jack device driver. The user simply needs to provide a table of adc range and connection states. Then, extcon framework will automatically notify others. Changes in V1: added Lars-Peter Clausen suggested changes: Using macros to get rid of boiler plate code such as devm_kzalloc and module_platform_driver.Other changes suggested are related to coding guidelines. Changes in V2: Removed some unnecessary checks and changed the way we are un-regitering extcon and freeing the irq while removing. Changes in V3: Renamed the files to comply with extcon naming. Changes in V4: Added the cancel_work_sync during removing of driver. Changes in V5: Added the dependency of IIO in Kconfig. Changes in V6: Some nitpicks related to naming.

2012-06-26Extcon: Arizona: Add driver for Wolfson Arizona class devicesMark Brown1-0/+1
Most Wolfson Arizona class audio hub CODECs include a flexible ultra low power accessory detection subsystem. This driver exposes initial support for this subsystem via the Extcon framework, implementing support for ultra low power detection of headphone and headset with the ability to detect the polarity of a headset. The functionality of the devices is much richer and more flexible than the current driver, future patches will extend the features of the driver to more fully exploit this.

The extcon-max8997 driver is implemented based on 'drivers/misc/ max8997-muic.c' and then use Extcon interface instead of callback function in struct max8997_muic_platform_data to notify cable state of notifee which want to know always newly cable state when external connector(e.g., USB, TA, JIG) is attached or detached. v1 - Use Extcon interface to notify cable state of notifee instead of callback function when external connector is attached or detached. - Bug fix of getting platform_data for irq_base value.

2012-04-20Extcon (external connector): import Android's switch class and modify.MyungJoo Ham1-0/+5
External connector class (extcon) is based on and an extension of Android kernel's switch class located at linux/drivers/switch/. This patch provides the before-extension switch class moved to the location where the extcon will be located (linux/drivers/extcon/) and updates to handle class properly. The before-extension class, switch class of Android kernel, commits imported are: switch: switch class and GPIO drivers. (splitted) Author: Mike Lockwood <lockwood@android.com> switch: Use device_create instead of device_create_drvdata.
