Adding a phy driver for USB 3.0 PHY controller present on Exynos5 series of SoCs alongwith DWC3 controller for USB 3.0 operations.
This driver is inline with Kamil's USB 2.0 phy driver. [1] Few functions used to translate ref clock rate are common to Kamil's changes. So we can figure out how to re-use them across these drivers.
Theses patches are based on usb-next branch and tested with Kishon's patches for adapting DWC3 to generic phy framework, [2] on smdk5250 as well as smdk5420 board.
