1menuconfig EXTCON 2 tristate "External Connector Class (extcon) support" 3 help 4 Say Y here to enable external connector class (extcon) support. 5 This allows monitoring external connectors by userspace 6 via sysfs and uevent and supports external connectors with 7 multiple states; i.e., an extcon that may have multiple 8 cables attached. For example, an external connector of a device 9 may be used to connect an HDMI cable and a AC adaptor, and to 10 host USB ports. Many of 30-pin connectors including PDMI are 11 also good examples. 12 13if EXTCON 14 15comment "Extcon Device Drivers" 16 17config EXTCON_ADC_JACK 18 tristate "ADC Jack extcon support" 19 depends on IIO 20 help 21 Say Y here to enable extcon device driver based on ADC values. 22 23config EXTCON_ARIZONA 24 tristate "Wolfson Arizona EXTCON support" 25 depends on MFD_ARIZONA && INPUT && SND_SOC 26 help 27 Say Y here to enable support for external accessory detection 28 with Wolfson Arizona devices.
