2 tristate "USB Type-C Connector System Software Interface driver"
3 depends on !CPU_BIG_ENDIAN
5 USB Type-C Connector System Software Interface (UCSI) is a
6 specification for an interface that allows the operating system to
7 control the USB Type-C ports. On UCSI system the USB Type-C ports
8 function autonomously by default, but in order to get the status of
9 the ports and support basic operations like role swapping, the driver
10 is required. UCSI is available on most of the new Intel based systems
11 that are equipped with Embedded Controller and USB Type-C ports.
13 UCSI specification does not define the interface method, so depending
14 on the platform, ACPI, PCI, I2C, etc. may be used. Therefore this
15 driver only provides the core part, and separate drivers are needed
16 for every supported interface method.
18 The UCSI specification can be downloaded from:

27 tristate "UCSI Interface Driver for Cypress CCGx"
30 This driver enables UCSI support on platforms that expose a
31 Cypress CCGx Type-C controller over I2C interface.

37 tristate "UCSI ACPI Interface Driver"
40 This driver enables UCSI support on platforms that expose UCSI
41 interface as ACPI device. On new Intel Atom based platforms starting
42 from Broxton SoCs and Core platforms stating from Skylake, UCSI is an
43 ACPI enumerated device.
