The Configuration Channel may also be used to detect optional 12a7c42106SHeikki Krogerus Accessory Modes - Analog Audio and Debug - and if USB Power Delivery 13a7c42106SHeikki Krogerus is supported, the Alternate Modes, where the connector is used for 14a7c42106SHeikki Krogerus something else then USB communication. 15fab92884SHeikki Krogerus 16a7c42106SHeikki Krogerus USB Power Delivery Specification defines a protocol that can be used 17a7c42106SHeikki Krogerus to negotiate the voltage and current levels with the connected 18a7c42106SHeikki Krogerus partners. USB Power Delivery allows higher voltages then the normal 19a7c42106SHeikki Krogerus 5V, up to 20V, and current up to 5A over the cable. The USB Power 20a7c42106SHeikki Krogerus Delivery protocol is also used to negotiate the optional Alternate 21a7c42106SHeikki Krogerus Modes when they are supported. USB Power Delivery does not depend on 22a7c42106SHeikki Krogerus USB Type-C connector, however it is mostly used together with USB 23a7c42106SHeikki Krogerus Type-C connectors. 24a7c42106SHeikki Krogerus 25a7c42106SHeikki Krogerus USB Type-C and USB Power Delivery Specifications define a set of state 26a7c42106SHeikki Krogerus machines that need to be implemented in either software or firmware. 27a7c42106SHeikki Krogerus Simple USB Type-C PHYs, for example USB Type-C Port Controller 28a7c42106SHeikki Krogerus Interface Specification compliant "Port Controllers" need the state 29a7c42106SHeikki Krogerus machines to be handled in the OS, but stand-alone USB Type-C and Power 30a7c42106SHeikki Krogerus Delivery controllers handle the state machines inside their firmware. 31a7c42106SHeikki Krogerus The USB Type-C and Power Delivery controllers usually function 32a7c42106SHeikki Krogerus autonomously, and do not necessarily require drivers. 33a7c42106SHeikki Krogerus 34a7c42106SHeikki Krogerus Enable this configurations option if you have USB Type-C connectors on 35a7c42106SHeikki Krogerus your system and 1) you know your USB Type-C hardware requires OS 36a7c42106SHeikki Krogerus control (a driver) to function, or 2) if you need to be able to read 37a7c42106SHeikki Krogerus the status of the USB Type-C ports in your system, or 3) if you need 38a7c42106SHeikki Krogerus to be able to swap the power role (decide are you supplying or 39a7c42106SHeikki Krogerus consuming power over the cable) or data role (host or device) when 40a7c42106SHeikki Krogerus both roles are supported. 41a7c42106SHeikki Krogerus 42a7c42106SHeikki Krogerus For more information, see the kernel documentation for USB Type-C 43a7c42106SHeikki Krogerus Connector Class API (Documentation/driver-api/usb/typec.rst) 44a7c42106SHeikki Krogerus <https://www.kernel.org/doc/html/latest/driver-api/usb/typec.html> 45a7c42106SHeikki Krogerus and ABI (Documentation/ABI/testing/sysfs-class-typec). 46a7c42106SHeikki Krogerus 47a7c42106SHeikki Krogerusif TYPEC 48fab92884SHeikki Krogerus 49ae8a2ca8SHeikki Krogerussource "drivers/usb/typec/tcpm/Kconfig" 503c4fb9f1SHeikki Krogerus 51c1b0bc2dSHeikki Krogerussource "drivers/usb/typec/ucsi/Kconfig" 52c1b0bc2dSHeikki Krogerus 531c48c759SBiju Dasconfig TYPEC_HD3SS3220 541c48c759SBiju Das tristate "TI HD3SS3220 Type-C DRP Port controller driver" 551c48c759SBiju Das depends on I2C 56da4b5d18SMao Wenan depends on USB_ROLE_SWITCH 571c48c759SBiju Das help 581c48c759SBiju Das Say Y or M here if your system has TI HD3SS3220 Type-C DRP Port 591c48c759SBiju Das controller driver. 601c48c759SBiju Das 611c48c759SBiju Das If you choose to build this driver as a dynamically linked module, the 621c48c759SBiju Das module will be called hd3ss3220.ko. 631c48c759SBiju Das 640a4c005bSHeikki Krogerusconfig TYPEC_TPS6598X 650a4c005bSHeikki Krogerus tristate "TI TPS6598x USB Power Delivery controller driver" 660a4c005bSHeikki Krogerus depends on I2C 67e9ccc35bSBryan O'Donoghue depends on REGMAP_I2C 68e9ccc35bSBryan O'Donoghue depends on USB_ROLE_SWITCH || !USB_ROLE_SWITCH 690a4c005bSHeikki Krogerus help 700a4c005bSHeikki Krogerus Say Y or M here if your system has TI TPS65982 or TPS65983 USB Power 710a4c005bSHeikki Krogerus Delivery controller. 720a4c005bSHeikki Krogerus 730a4c005bSHeikki Krogerus If you choose to build this driver as a dynamically linked module, the 740a4c005bSHeikki Krogerus module will be called tps6598x.ko. 750a4c005bSHeikki Krogerus 76da95cc1dSHans de Goedesource "drivers/usb/typec/mux/Kconfig" 77da95cc1dSHans de Goede 780e3bb7d6SHeikki Krogerussource "drivers/usb/typec/altmodes/Kconfig" 790e3bb7d6SHeikki Krogerus 80a7c42106SHeikki Krogerusendif # TYPEC 81
