[PATCH v7 0/2] dts: Add usb2phy to Exynos 5250

[Vivek Gautam]

Next version of patch for Kamil's patch:
[PATCH v6 4/8] dts: Add usb2phy to Exynos 5250
https://lkml.org/lkml/2014/1/29/302

Based on 'for-next' branch of Kgene's linux-samsung tree.
Tested with driver side patches:
[PATCH 0/2] usb: ehci/ohci-exynos: Move to generic phy framework
https://www.mail-archive.com/linux-usb@vger.kernel.org/msg41246.html

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.
