menuconfig EXTCON tristate "External Connector Class (extcon) support" help 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. if EXTCON comment "Extcon Device Drivers" config EXTCON_ADC_JACK tristate "ADC Jack extcon support" depends on IIO help Say Y here to enable extcon device driver based on ADC values. config EXTCON_ARIZONA tristate "Wolfson Arizona EXTCON support" depends on MFD_ARIZONA && INPUT && SND_SOC help Say Y here to enable support for external accessory detection with Wolfson Arizona devices.
