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.

Say Y here to enable external connector class (extcon) support.
This allows monitoring external connectors by userspace
via sysfs and uevent and supports external connectors with
multiple states; i.e., an extcon that may have multiple
cables attached. For example, an external connector of a device
may be used to connect an HDMI cable and a AC adaptor, and to
host USB ports. Many of 30-pin connectors including PDMI are
also good examples.

extcon: extcon-axp288: Use P-Unit semaphore lock for register accesses use low level P-Unit semaphore lock for axp288 register accesses directly and for more than one access a time, to reduce the number of times this semaphore is locked and released which is an expensive operation. i2c-bus to the XPower is shared between the kernel and the SoCs P-Unit. The P-Unit has a semaphore wich the kernel must lock for axp288 register accesses. When the P-Unit semaphore is locked CPU and GPU power states cannot change or the system will freeze. The P-Unit semaphore lock is already managed inside the regmap access logic, but for each access the semaphore is locked and released. So use directly iosf_mbi_(un)block_punit_i2c_access(), we are safe in doing so because nested calls to the same semaphore are turned to nops.

extcon: axp288: Set USB role where necessary The AXP288 BC1.2 charger detection / extcon code may seem like a strange place to add code to control the USB role-switch on devices with an AXP288, but there are 2 reasons to do this inside the axp288 extcon code: 1) On many devices the USB role is controlled by ACPI AML code, but the AML code only switches between the host and none roles, because of Windows not really using device mode. To make device mode work we need to toggle between the none/device roles based on Vbus presence, and the axp288 extcon gets interrupts on Vbus insertion / removal. 2) In order for our BC1.2 charger detection to work properly the role mux must be properly set to device mode before we do the detection. Also note the Kconfig help-text / obsolete depends on USB_PHY which are remnants from older never upstreamed code also controlling the mux from the axp288 extcon code. This commit also adds code to get notifications from the INT3496 extcon device, which is used on some devices to notify the kernel about id-pin changes instead of them being handled through AML code. This fixes: -Device mode not working on most CHT devices with an AXP288 -Host mode not working on devices with an INT3496 ACPI device -Charger-type misdetection (always SDP) on devices with an INT3496 when the USB role (always) gets initialized as host Signed-off-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

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.

extcon: max8997: select IRQ_DOMAIN instead of depending on it IRQ_DOMAIN is a hidden (not user visible) symbol. Users cannot set it directly thru "make *config", so drivers should select it instead of depending on it if they need it. Relying on it being set for a dependency is risky. Consistently using "select" or "depends on" can also help reduce Kconfig circular dependency issues. Therefore, change EXTCON_MAX8997's use of "depends on" for IRQ_DOMAIN to "select".

extcon: usbc-tusb320: Add USB TYPE-C support The TI TUSB320 seems like a better fit for USB TYPE-C subsystem, which can expose details collected by the TUSB320 in a far more precise way than extcon. Since there are existing users in the kernel and in DT which depend on the extcon interface, keep it for now. Add TYPE-C interface and expose the supported supply current, direction and connector polarity via the TYPE-C interface.

extcon: Add driver for TI TUSB320 This patch adds an extcon driver for the TI TUSB320 USB Type-C device. This can be used to detect whether the port is configured as a downstream or upstream facing port.

extcon: add Realtek DHC RTD SoC Type-C driver This patch adds the extcon driver for Realtek DHC (digital home center) RTD SoCs type-c module. This can be used to detect whether the port is configured as a downstream or upstream facing port. And notify the status of extcon to listeners.

Say Y here to enable extcon support for USB Type C cable detection
when using the Realtek RTD SoC USB Type-C port.
The DHC (Digital Home Hub) RTD series SoC contains a type c module.
This driver will detect the status of the type-c port.
