config TYPEC_UCSI
tristate "USB Type-C Connector System Software Interface driver"
depends on !CPU_BIG_ENDIAN
help
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.

tristate "UCSI Interface Driver for Cypress CCGx"
depends on I2C
help
This driver enables UCSI support on platforms that expose a
Cypress CCGx Type-C controller over I2C interface.
To compile the driver as a module, choose M here: the module will be
called ucsi_ccg.
config UCSI_ACPI
tristate "UCSI ACPI Interface Driver"
depends on ACPI
help
This driver enables UCSI support on platforms that expose UCSI
interface as ACPI device. On new Intel Atom based platforms starting
from Broxton SoCs and Core platforms stating from Skylake, UCSI is an
ACPI enumerated device.
To compile the driver as a module, choose M here: the module will be
called ucsi_acpi
