On UCSI system the USB Type-C ports 10 function autonomously by default, but in order to get the status of 11 the ports and support basic operations like role swapping, the driver 12 is required. UCSI is available on most of the new Intel based systems 13 that are equipped with Embedded Controller and USB Type-C ports. 14 15 UCSI specification does not define the interface method, so depending 16 on the platform, ACPI, PCI, I2C, etc. may be used. Therefore this 17 driver only provides the core part, and separate drivers are needed 18 for every supported interface method. 19 20 The UCSI specification can be downloaded from: 21 http://www.intel.com/content/www/us/en/io/universal-serial-bus/usb-type-c-ucsi-spec.html 22 23 To compile the driver as a module, choose M here: the module will be 24 called typec_ucsi. 25 26if TYPEC_UCSI 27 28config UCSI_CCG 29 tristate "UCSI Interface Driver for Cypress CCGx" 30 depends on I2C 31 help 32 This driver enables UCSI support on platforms that expose a 33 Cypress CCGx Type-C controller over I2C interface. 34 35 To compile the driver as a module, choose M here: the module will be 36 called ucsi_ccg. 37 38config UCSI_ACPI 39 tristate "UCSI ACPI Interface Driver" 40 depends on ACPI 41 help 42 This driver enables UCSI support on platforms that expose UCSI 43 interface as ACPI device.
