Subject: [PATCH v5 0/3] ARM: Exynos5250: Enabling dwc3-exynos driver

This patch-set is in continuation with patch-series:
[PATCH v4 0/4] Enable ehci, ohci and dwc3 devices on exynos5250
out of which follwowing patches have been picked up:
ARM: Exynos5250: Enabling ehci-s5p driver
ARM: Exynos5250: Enabling ohci-exynos driver

Based on following patch-set for Samsung's usb PHY enablement:
[PATCH v4 0/2] ARM: Exynos5250: Enabling samsung usb phy

and further depends on dwc3-exynos driver patch-set:
[PATCH 0/2] dwc3: exynos: Device tree fixes

Changes from v4:
- Aligning with the recently merged common clock framework, thereby
no place for clock file changes. ;-)
- Adding proper binding documentation as per latest bindings changes in
dwc3 driver (dwc3/core.c as well as for dwc3-exynos.c change reflected
by above patch-set.
- Bifurcating the patch to separate our Documentation, arch and dts changes.
