For example, an external connector of a device 10 may be used to connect an HDMI cable and a AC adaptor, and to 11 host USB ports. Many of 30-pin connectors including PDMI are 12 also good examples. 13 14if EXTCON 15 16comment "Extcon Device Drivers" 17 18config EXTCON_ADC_JACK 19 tristate "ADC Jack extcon support" 20 depends on IIO 21 help 22 Say Y here to enable extcon device driver based on ADC values. 23 24config EXTCON_AXP288 25 tristate "X-Power AXP288 EXTCON support" 26 depends on MFD_AXP20X && USB_SUPPORT && X86 && ACPI 27 select USB_ROLE_SWITCH 28 help 29 Say Y here to enable support for USB peripheral detection 30 and USB MUX switching by X-Power AXP288 PMIC. 31 32config EXTCON_FSA9480 33 tristate "FSA9480 EXTCON Support" 34 depends on INPUT && I2C 35 select IRQ_DOMAIN 36 select REGMAP_I2C 37 help 38 If you say yes here you get support for the Fairchild Semiconductor 39 FSA9480 microUSB switch and accessory detector chip.
