[PATCH v6 0/8] Enable USB 3.0 support on Exynos5 systems

[PATCH v6 0/8] Enable USB 3.0 support on Exynos5 systems

[Vivek Gautam]

From: Vivek gautam <gautam.vivek@samsung.com>

Based on 'for-next' branch of Kgene's linux-samsung tree;
along with dts patches for USB 2.0 phy[1], and Exynos5800 [2].
Also based on the latest USB 3.0 DRD phy driver patches posted [3].

Changes from v5:
 - Added node reference names for new boards.
 - Removed 'samsung,pmu-offset' porperty from nodes, since with latest driver
   bindings this is not required.
 - Added aliase nodes in Exynos5420 to facilitate latest driver bindings.
 - Added patch to add VBUS regulator for peach-pi board also.
 - Dropped patches removing older usb-phy driver:
   usb-phy: samsung-usb3: Remove older phy-samsung-usb3 driver
   ARM: exynos_defconfig: Remove SAMSUNG_USB3PHY config
   as appeared in V5 version of this series.
   Will post them separately after the new driver is merged.
