[PATCH V3 0/4] dts: Add usb2phy to Exynos 5250/5420

[Vikas Sajjan]

Based on 'for-next' branch of Kgene's linux-samsung tree.
These patches are as per discussions on the driver side patches
which have already been acked. [1]

Changes from v2:
	- Addressed kukjin's comments to update DT binding documentation for sysreg.
	- removed the version for each patch. Made all patches version as same.

Changes from v1:
 - Rebase on 'for-next' branch.
 - Removed 'phy-names' property as per discuusion in the driver patches. [1]

V1 of this series was the next version for earlier patch-series:
[PATCH v7 0/2] dts: Add usb2phy to Exynos 5250 [2]

Changes from v7 series:
 - Added patches to enable usb 2.0 support on exynos5420;
   which include dt nodes for usb2phy as well as ehci and ohci
   controllers.

Changes from v6:
 - Splitted the patch into two:
    adding syscon nodes to Exynos5250 and Exynos5420 in first;
    and phy entry change in the second.
 - Changed the name of phandle for usb2phy from 'usb2_phy_new'
   to 'usb2_phy_gen' indicating generic phy.
 - Using clock macros in dt entries.
