1 2menuconfig TYPEC 3 tristate "USB Type-C Support" 4 help 5 USB Type-C Specification defines a cable and connector for USB where 6 only one type of plug is supported on both ends, i.e. there will not 7 be Type-A plug on one end of the cable and Type-B plug on the other. 8 Determination of the host-to-device relationship happens through a 9 specific Configuration Channel (CC) which goes through the USB Type-C 10 cable. The Configuration Channel may also be used to detect optional 11 Accessory Modes - Analog Audio and Debug - and if USB Power Delivery 12 is supported, the Alternate Modes, where the connector is used for 13 something else then USB communication. 14 15 USB Power Delivery Specification defines a protocol that can be used 16 to negotiate the voltage and current levels with the connected 17 partners. USB Power Delivery allows higher voltages then the normal 18 5V, up to 20V, and current up to 5A over the cable. The USB Power 19 Delivery protocol is also used to negotiate the optional Alternate 20 Modes when they are supported. USB Power Delivery does not depend on 21 USB Type-C connector, however it is mostly used together with USB 22 Type-C connectors. 23 24 USB Type-C and USB Power Delivery Specifications define a set of state 25 machines that need to be implemented in either software or firmware. 26 Simple USB Type-C PHYs, for example USB Type-C Port Controller 27 Interface Specification compliant "Port Controllers" need the state 28 machines to be handled in the OS, but stand-alone USB Type-C and Power 29 Delivery controllers handle the state machines inside their firmware. 30 The USB Type-C and Power Delivery controllers usually function 31 autonomously, and do not necessarily require drivers. 32 33 Enable this configurations option if you have USB Type-C connectors on 34 your system and 1) you know your USB Type-C hardware requires OS 35 control (a driver) to function, or 2) if you need to be able to read 36 the status of the USB Type-C ports in your system, or 3) if you need 37 to be able to swap the power role (decide are you supplying or 38 consuming power over the cable) or data role (host or device) when 39 both roles are supported. 40 41 For more information, see the kernel documentation for USB Type-C 42 Connector Class API (Documentation/driver-api/usb/typec.rst) 43 <https://www.kernel.org/doc/html/latest/driver-api/usb/typec.html> 44 and ABI (Documentation/ABI/testing/sysfs-class-typec). 45 46if TYPEC 47 48config TYPEC_TCPM 49 tristate "USB Type-C Port Controller Manager" 50 depends on USB 51 help 52 The Type-C Port Controller Manager provides a USB PD and USB Type-C 53 state machine for use with Type-C Port Controllers. 54 55if TYPEC_TCPM 56 57source "drivers/usb/typec/fusb302/Kconfig" 58 59config TYPEC_WCOVE 60 tristate "Intel WhiskeyCove PMIC USB Type-C PHY driver" 61 depends on ACPI 62 depends on INTEL_SOC_PMIC 63 depends on INTEL_PMC_IPC 64 depends on BXT_WC_PMIC_OPREGION 65 help 66 This driver adds support for USB Type-C detection on Intel Broxton 67 platforms that have Intel Whiskey Cove PMIC.
