usb: typec: qcom: Add Qualcomm PMIC Type-C driver This commit adds a QCOM PMIC TCPM driver with an initial pm8150b block. The driver is layered as follows: qcom_pmic_typec.c : Responsible for registering with TCPM and arbitrates access to the Type-C and PDPHY hardware blocks in one place. This presents a single TCPM device to device to the Linux TCPM layer. qcom_pmic_typec_pdphy.c: Responsible for interfacing with the PDPHY hardware and processing power-delivery related calls from TCPM. This hardware binding can be extended to facilitate similar hardware in different PMICs. qcom_pmic_typec_port.c: Responsible for notifying and processing Type-C related calls from TCPM. Similar to the pdphy this layer can be extended to handle the specifics of different Qualcomm PMIC Type-C port managers. This code provides all of the same functionality as the existing qcom typec driver plus power-delivery as well. As a result commit 6c8cf3695176 ("usb: typec: Add QCOM PMIC typec detection driver") can be deleted entirely.

usb: typec: add support for STUSB160x Type-C controller family STMicroelectronics USB Type-C port controllers use I2C interface to configure, control and read the operation status of the device. All ST USB Type-C port controllers are based on the same I2C register map. That's why this driver can be used with all ST USB Type-C ICs. Some ST USB Type-C port controllers are Dual Role Port (DRP), only Sink or Source, some supports USB Power Delivery. This can be configured through connector device tree bindings. This driver is a basic Type-C port controller driver, with no power delivery support. It allows to configure ST USB Type-C port controller. Interrupt is supported and enables CC connection events, to detect attach and detach and update Type-C subsystem accordingly as well as usb role switch. ST USB Type-C port controller can be supplied in three different ways depending on the target application: - through VDD pin only (so VDD is the main supply) - through VSYS pin only (so VSYS is the main supply) - through VDD and VSYS pins. When both VDD and VSYS power supplies are present, the low power supply VSYS is selected as main supply when VSYS voltage is above 3.1V, else VDD is selected as main supply. In case of Source or Dual port type, if VDD supply is present, it has to be enabled in case of Source power role to provide Vbus. When interrupt support is available, VDD supply is dynamically managed upon attach/detach interrupt. When there is no interrupt support, VDD supply is enabled by default.

usb: typec: driver for TI TPS6598x USB Power Delivery controllers Driver for TI TPS65982, TPS65983 and other TPS6598x family stand alone USB Power Delivery controllers. The driver will at this stage only register the port and partners attached to it, so cables and alternate modes are not yet registered. Both power and data role swapping is supported.

usb: typec: Add support for UCSI interface UCSI - USB Type-C Connector System Software Interface - is a specification that defines set of registers and data structures for controlling the USB Type-C ports. It's designed for systems where an embedded controller (EC) is in charge of the USB Type-C PHY or USB Power Delivery controller. It is designed for systems with EC, but it is not limited to them, and for example some USB Power Delivery controllers will use it as their direct control interface. With UCSI the EC (or USB PD controller) acts as the port manager, implementing all USB Type-C and Power Delivery state machines. The OS can use the interfaces for reading the status of the ports and controlling basic operations like role swapping. The UCSI specification highlights the fact that it does not define the interface method (PCI/I2C/ACPI/etc.). Therefore the driver is implemented as library and every supported interface method needs its own driver. Driver for ACPI is provided in separate patch following this one. The initial driver includes support for all required features from UCSI specification version 1.0 (getting connector capabilities and status, and support for power and data role swapping), but none of the optional UCSI features (alternate modes, power source capabilities, and cable capabilities).

usb: USB Type-C connector class The purpose of USB Type-C connector class is to provide unified interface for the user space to get the status and basic information about USB Type-C connectors on a system, control over data role swapping, and when the port supports USB Power Delivery, also control over power role swapping and Alternate Modes.
