Extcon (external connector): import Android's switch class and modify. 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. Author: Arve Hjønnevåg <arve@android.com> In this patch, upon the commits of Android kernel, we have added: - Relocated and renamed for extcon. - Comments, module name, and author information are updated - Code clean for successing patches - Bugfix: enabling write access without write functions - Class/device/sysfs create/remove handling - Added comments about uevents - Format changes for extcon_dev_register() to have a parent dev.

Changes from v2 - Updated name_show - Sysfs entries are handled by class itself. - Updated the method to add/remove devices for the class - Comments on uevent send - Able to become a module - Compatible with Android platform Changes from RFC - Renamed to extcon (external connector) from multistate switch - Added a seperated directory (drivers/extcon) - Added kerneldoc comments - Removed unused variables from extcon_gpio.c - Added ABI Documentation.

extcon: Allow compile test of GPIO consumers if !GPIOLIB The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled.

extcon: add Maxim MAX3355 driver Maxim Integrated MAX3355E chip integrates a charge pump and comparators to enable a system with an integrated USB OTG dual-role transceiver to function as an USB OTG dual-role device. In addition to sensing/controlling Vbus, the chip also passes thru the ID signal from the USB OTG connector. On some Renesas boards, this signal is just fed into the SoC thru a GPIO pin -- there's no real OTG controller, only host and gadget USB controllers sharing the same USB bus; however, we'd like to allow host or gadget drivers to be loaded depending on the cable type, hence the need for the MAX3355 extcon driver. The Vbus status signals are also wired to GPIOs (however, we aren't currently interested in them), the OFFVBUS# signal is controlled by the host controllers, there's also the SHDN# signal wired to a GPIO, it should be driven high for the normal operation.

extcon: sm5502: Add support new SM5502 extcon device driver This patch add new SM5502 MUIC(Micro-USB Interface Controller) device by using EXTCON subsystem. The extcon-sm5502 driver is capable of identifying the type of the external power source and attached accessory. An external power sources, such as Deticated Charger or a standard USB port, are able to charge the battery in the smart phone via the connector. Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>

extcon: usb-gpio: Introduce gpio usb extcon driver 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.

extcon: Allow compile test of GPIO consumers if !GPIOLIB The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate. If GPIOLIB=n and asm-generic/gpio.h is not used: drivers/extcon/extcon-usb-gpio.c: In function ‘usb_extcon_detect_cable’: drivers/extcon/extcon-usb-gpio.c:63: error: implicit declaration of function ‘gpiod_get_value_cansleep’ drivers/extcon/extcon-usb-gpio.c: In function ‘usb_extcon_probe’: drivers/extcon/extcon-usb-gpio.c:116: error: implicit declaration of function ‘devm_gpiod_get’ drivers/extcon/extcon-usb-gpio.c:116: warning: assignment makes pointer from integer without a cast drivers/extcon/extcon-usb-gpio.c:122: error: implicit declaration of function ‘gpiod_set_debounce’ drivers/extcon/extcon-usb-gpio.c:129: error: implicit declaration of function ‘gpiod_to_irq’ Add the missing #include <linux/gpio/consumer.h> to fix this.

extcon: cros-ec: Add extcon-cros-ec driver to support display out This is the driver for the USB Type C cable detection mechanism built into the ChromeOS Embedded Controller on systems that have USB Type-C ports. At present, this allows for the presence of display out, but in future, it may also be used to notify host and device type cables and the presence of power.
