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.
