Help text

USB Type-C Connector System Software Interface (UCSI) is a specification for an interface that allows the operating system to control the USB Type-C ports. On UCSI system the USB Type-C ports function autonomously by default, but in order to get the status of the ports and support basic operations like role swapping, the driver is required. UCSI is available on most of the new Intel based systems that are equipped with Embedded Controller and USB Type-C ports.

UCSI specification does not define the interface method, so depending on the platform, ACPI, PCI, I2C, etc. may be used. Therefore this driver only provides the core part, and separate drivers are needed for every supported interface method.

The UCSI specification can be downloaded from: http://www.intel.com/content/www/us/en/io/universal-serial-bus/usb-type-c-ucsi-spec.html

To compile the driver as a module, choose M here: the module will be called typec_ucsi.
