This patchset adds a generic USB repeater framework to be used by platforms that have eUSB2 support and want to have USB 2.0 compliance. In such cases there is a device between the eUSB2 PHY and the actual connector. That device is basically a repeater and the most important thing it does is to level shift in both directions. Such a device needs to be controlled in software usually by the PHY or by the HC. So add a generic framework with basic ops to allow consumer drivers to get a phandle to it and to control it. Also add the SM8550 PMIC eUSB2 repeater which uses the generic framework.
