On UCSI system the USB Type-C ports 12 function autonomously by default, but in order to get the status of 13 the ports and support basic operations like role swapping, the driver 14 is required. UCSI is available on most of the new Intel based systems 15 that are equipped with Embedded Controller and USB Type-C ports. 16 17 UCSI specification does not define the interface method, so depending 18 on the platform, ACPI, PCI, I2C, etc. may be used. Therefore this 19 driver only provides the core part, and separate drivers are needed 20 for every supported interface method. 21 22 The UCSI specification can be downloaded from: 23 https://www.intel.com/content/www/us/en/io/universal-serial-bus/usb-type-c-ucsi-spec.html 24 25 To compile the driver as a module, choose M here: the module will be 26 called typec_ucsi. 27 28if TYPEC_UCSI 29 30config UCSI_CCG 31 tristate "UCSI Interface Driver for Cypress CCGx" 32 depends on I2C 33 help 34 This driver enables UCSI support on platforms that expose a 35 Cypress CCGx Type-C controller over I2C interface. 36 37 To compile the driver as a module, choose M here: the module will be 38 called ucsi_ccg. 39 40config UCSI_ACPI 41 tristate "UCSI ACPI Interface Driver" 42 depends on ACPI 43 help 44 This driver enables UCSI support on platforms that expose UCSI 45 interface as ACPI device.
