Public bug reported:
Description:
With USB Type-C the OS needs to be able to switch the USB data role between
host mode and device mode. This is because USB Type-C connection will select
the role randomly.
The USB Type-C ports on GLK are controlled via UCSI (USB Type-C System Software
Interface). We will implement support for UCSI in this task. The UCSI will be
implemented as a "library" inside kernel. The actual UCSI device on GLK is ACPI
enumerated device, so we will implement driver for it. This driver will simply
"register" itself with the library that will do the rest. The "library"
approach is used because UCSI does not specify the actual bus (I2C, SPI, etc.)
that is used to interface with the Type-C ports. It only specifies the data
structures. That means that even though on GLK we have ACPI enumerate device
for the UCSI interface, on future platforms it may be something else like PCI
enumerate device.
Target Kernel:4.13
Target Release:17.10
