UCSI is used on several Intel Broxton SoC based platforms. Things that UCSI can be used to control include at least USB Data Role swapping, Power Role swapping and controlling of Alternate Modes on top of providing general details about the port and the partners that are attached to it. The initial purpose of the UCSI driver is to make sure USB is in host mode on desktop and server systems that are USB dual role capable, and provide UCSI interface. The goal is to integrate the driver later to an USB Type-C framework for Linux kernel, and at the same time add support for more extensive USB Type-C port control that UCSI offers, for example data role swapping, power role swapping, Alternate Mode control etc. The UCSI specification is public can be obtained from here: http://www.intel.com/content/www/us/en/io/universal-serial-bus/usb-type-c-ucsi-spec.html Signed-off-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
