Hi Kamil,

Would you add 'phy-exynos5250-usb.c' file? :-)

Now, I am testing Exynos5250 USB HOST with your patchset.
However, it makes error because there is no PHY driver for
Exynos5250.

  WARNING: CPU: 0 PID: 18 at drivers/phy/phy-core.c:366 phy_get+0x1e8/0x224()
  Device: exynos-ehci
  missing string
  .....

Best regards,
Jingoo Han
