Hi all!

This patchset adds support for the USB 2.0 PHY of the Exynos990 SoC.
This SoC has a combo PHY that supports highspeed, superspeed USB and
DisplayPort, however due to my inability to test the superspeed part of
the combo phy (device always enumerated as high-speed, even on the
vendor kernels/bootloaders) only the highspeed part is brought up.

These changes have been tested and confirmed working (with the USB_ETH
gadget and telnet/ssh in a ramdisk) on a device from the hubble family
(x1s) and also a device from the canvas family (c1s).
