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 select USB_ROLE_SWITCH 52 select POWER_SUPPLY 53 help 54 The Type-C Port Controller Manager provides a USB PD and USB Type-C 55 state machine for use with Type-C Port Controllers. 56 57if TYPEC_TCPM 58 59config TYPEC_TCPCI 60 tristate "Type-C Port Controller Interface driver" 61 depends on I2C 62 select REGMAP_I2C 63 help 64 Type-C Port Controller driver for TCPCI-compliant controller. 65 66config TYPEC_RT1711H 67 tristate "Richtek RT1711H Type-C chip driver" 68 depends on I2C 69 select TYPEC_TCPCI 70 help 71 Richtek RT1711H Type-C chip driver that works with 72 Type-C Port Controller Manager to provide USB PD and USB 73 Type-C functionalities. 74 75source "drivers/usb/typec/fusb302/Kconfig" 76 77config TYPEC_WCOVE 78 tristate "Intel WhiskeyCove PMIC USB Type-C PHY driver" 79 depends on ACPI 80 depends on INTEL_SOC_PMIC 81 depends on INTEL_PMC_IPC 82 depends on BXT_WC_PMIC_OPREGION 83 help 84 This driver adds support for USB Type-C detection on Intel Broxton 85 platforms that have Intel Whiskey Cove PMIC.
