[PATCHv5 0/4] Enable usbphy and hsotg for exynos4

[Chanho Park]

This patchset enables a exynos4 usbphy and hsotg DT node for exynos4. The usb
phy node uses generic exynos phy driver. The driver uses PMU syscon and SYSREG
syscon phandles.

Changes from v4:
 - Correct 4212/4412 PMU syscon node according to documentation

Change from v3:
 - Place a status field at the end of the nodes for readability

Change from v2:
 - Split 4x12 compatibles to 4212 and 4412

Changes from v1: Applied Tomasz Figa's comments
 - Document PMU syscon compatibles for exynos4210/4x12
 - Use clock macro instead of raw clock number
 - Correct phy name to "usb2-phy"

Chanho Park (4):
  ARM: dts: exynos4: add PMU syscon node
  ARM: dts: exynos4: add exynos_usbphy node
  ARM: dts: exynos4: add hsotg device node
  ARM: dts: exynos4412-trats2: enable usb nodes

[PATCHv5 1/4] ARM: dts: exynos4: add PMU syscon node

[Chanho Park]

This patch adds a PMU(Power Management Unit) syscon node. This
should be required for USB Phy syscon regmap I/F.

[Chanho Park]

This patch enables a exynos_usbphy node for exynos4 SoCs.
A exynos4x12 usb phy node is almost same with 4210's one
except compatible string and pmu syscon.
