usb: typec: Add support for retimers

2022-07-14T14:24:05Z

Introduce a retimer device class and associated functions that register and use retimer "switch" devices. These operate in a manner similar to the "mode-switch" and help configure retimers that exist between the Type-C connector and host controller(s). Type C ports can be linked to retimers using firmware node device references (again, in a manner similar to "mode-switch"). There are no new sysfs files being created; there is the new retimer class directory, but there are no class-specific files being created there.

usb: typec: Separate USB Power Delivery from USB Type-C

2022-06-12T04:49:47Z

Introducing a small device class for USB Power Delivery. The idea with it is that we do not mix any more USB Power Delivery information into the USB Type-C connectors only. This separation will make it possible to register USB Power Delivery devices also from other places, for example from USB Type-C Bridges (see USB Type-C Bridge Specification). The device class will not always deal with only the messages and objects that were negotiated with the partner, but instead messages and objects that can be used in the negotiation. That allows the USB PD devices to be shared and reconfigured. The ports can decide which objects are to be advertised to the partner before the contract is negotiated. It is also possible to allow the user space to make that decision if needed.

usb: typec: Support the WUSB3801 port controller

2022-02-17T15:23:18Z

WUSB3801 features a configurable port type, accessory detection, and plug orientation detection. It provides a hardware "ID" pin output for compatibility with USB 2.0 OTG PHYs. Add a typec class driver for it.

usb: typec: port-mapper: Convert to the component framework

2021-12-30T11:13:04Z

Instead of trying to keep track of the connections to the USB Type-C connectors separately, letting the component framework take care of that. From now on every USB Type-C connector will register itself as "aggregate" - component master - and anything that can be connected to it inside the system can then simply register itself as a generic component. The matching of the components and the connector shall rely on ACPI _PLD initially. Before registering itself as the aggregate, the connector will find all other ACPI devices that have matching _PLD crc hash with it (matching value in the pld_crc member of struct acpi_device), and add a component match entry for each one of them. Because only ACPI is supported for now, the driver shall only be build when ACPI is supported. This removes the need for the custom API that the driver exposed. The components and the connector can therefore exist completely independently of each other. The order in which they are registered, as well as are they modules or not, is now irrelevant.

usb: typec: Port mapping utility

2021-04-09T14:00:00Z

Adding functions that can be used to link/unlink ports - USB ports, TBT3/USB4 ports, DisplayPorts and so on - to the USB Type-C connectors they are attached to inside a system. The symlink that is created for the port device is named "connector". Initially only ACPI is supported. ACPI port object shares the _PLD (Physical Location of Device) with the USB Type-C connector that it's attached to.

usb: typec: Add QCOM PMIC typec detection driver

2020-10-09T13:14:43Z

The QCOM SPMI typec driver handles the role and orientation detection, and notifies client drivers using the USB role switch framework. It registers as a typec port, so orientation can be communicated using the typec switch APIs. The driver also attains a handle to the VBUS output regulator, so it can enable/disable the VBUS source when acting as a host/device.
