The Configuration Channel may also be used to detect optional 11a7c42106SHeikki Krogerus Accessory Modes - Analog Audio and Debug - and if USB Power Delivery 12a7c42106SHeikki Krogerus is supported, the Alternate Modes, where the connector is used for 13a7c42106SHeikki Krogerus something else then USB communication. 14fab92884SHeikki Krogerus 15a7c42106SHeikki Krogerus USB Power Delivery Specification defines a protocol that can be used 16a7c42106SHeikki Krogerus to negotiate the voltage and current levels with the connected 17a7c42106SHeikki Krogerus partners. USB Power Delivery allows higher voltages then the normal 18a7c42106SHeikki Krogerus 5V, up to 20V, and current up to 5A over the cable. The USB Power 19a7c42106SHeikki Krogerus Delivery protocol is also used to negotiate the optional Alternate 20a7c42106SHeikki Krogerus Modes when they are supported. USB Power Delivery does not depend on 21a7c42106SHeikki Krogerus USB Type-C connector, however it is mostly used together with USB 22a7c42106SHeikki Krogerus Type-C connectors. 23a7c42106SHeikki Krogerus 24a7c42106SHeikki Krogerus USB Type-C and USB Power Delivery Specifications define a set of state 25a7c42106SHeikki Krogerus machines that need to be implemented in either software or firmware. 26a7c42106SHeikki Krogerus Simple USB Type-C PHYs, for example USB Type-C Port Controller 27a7c42106SHeikki Krogerus Interface Specification compliant "Port Controllers" need the state 28a7c42106SHeikki Krogerus machines to be handled in the OS, but stand-alone USB Type-C and Power 29a7c42106SHeikki Krogerus Delivery controllers handle the state machines inside their firmware. 30a7c42106SHeikki Krogerus The USB Type-C and Power Delivery controllers usually function 31a7c42106SHeikki Krogerus autonomously, and do not necessarily require drivers. 32a7c42106SHeikki Krogerus 33a7c42106SHeikki Krogerus Enable this configurations option if you have USB Type-C connectors on 34a7c42106SHeikki Krogerus your system and 1) you know your USB Type-C hardware requires OS 35a7c42106SHeikki Krogerus control (a driver) to function, or 2) if you need to be able to read 36a7c42106SHeikki Krogerus the status of the USB Type-C ports in your system, or 3) if you need 37a7c42106SHeikki Krogerus to be able to swap the power role (decide are you supplying or 38a7c42106SHeikki Krogerus consuming power over the cable) or data role (host or device) when 39a7c42106SHeikki Krogerus both roles are supported. 40a7c42106SHeikki Krogerus 41a7c42106SHeikki Krogerus For more information, see the kernel documentation for USB Type-C 42a7c42106SHeikki Krogerus Connector Class API (Documentation/driver-api/usb/typec.rst) 43a7c42106SHeikki Krogerus <https://www.kernel.org/doc/html/latest/driver-api/usb/typec.html> 44a7c42106SHeikki Krogerus and ABI (Documentation/ABI/testing/sysfs-class-typec). 45a7c42106SHeikki Krogerus 46a7c42106SHeikki Krogerusif TYPEC 47fab92884SHeikki Krogerus 484b4e02c8SGuenter Roeckconfig TYPEC_TCPM 494b4e02c8SGuenter Roeck tristate "USB Type-C Port Controller Manager" 504b4e02c8SGuenter Roeck depends on USB 512000016cSHans de Goede select USB_ROLE_SWITCH 524b4e02c8SGuenter Roeck help 534b4e02c8SGuenter Roeck The Type-C Port Controller Manager provides a USB PD and USB Type-C 544b4e02c8SGuenter Roeck state machine for use with Type-C Port Controllers. 554b4e02c8SGuenter Roeck 5676f0c53dSGuenter Roeckif TYPEC_TCPM 5776f0c53dSGuenter Roeck 5876f0c53dSGuenter Roecksource "drivers/usb/typec/fusb302/Kconfig" 5976f0c53dSGuenter Roeck 60d2061f9cSHeikki Krogerusconfig TYPEC_WCOVE 61d2061f9cSHeikki Krogerus tristate "Intel WhiskeyCove PMIC USB Type-C PHY driver" 62d2061f9cSHeikki Krogerus depends on ACPI 63d2061f9cSHeikki Krogerus depends on INTEL_SOC_PMIC 64d2061f9cSHeikki Krogerus depends on INTEL_PMC_IPC 65d2061f9cSHeikki Krogerus depends on BXT_WC_PMIC_OPREGION 66d2061f9cSHeikki Krogerus help 67d2061f9cSHeikki Krogerus This driver adds support for USB Type-C detection on Intel Broxton 68d2061f9cSHeikki Krogerus platforms that have Intel Whiskey Cove PMIC.
