Since you're changing the name, I would have expected to see a removal
of the old enum type in this patch.  I don't see it.  After applying
all of your patches I find that S5P_USB_PHY_HOST and
S5P_USB_PHY_DEVICE are still defined and used.

$ git grep S5P_USB_PHY_HOST
arch/arm/mach-exynos/setup-usb-phy.c:   else if (type == S5P_USB_PHY_HOST)
arch/arm/mach-exynos/setup-usb-phy.c:   else if (type == S5P_USB_PHY_HOST)
arch/arm/plat-samsung/include/plat/usb-phy.h:   S5P_USB_PHY_HOST,

I believe that those usages of the old enum should also be switched
over and the old enum removed.
