phy: for 4.7

*) Add a new PHY driver for USB2 PHY on Northstar SoC
*) Add support for Broadcom NS2 SATA3 PHY in existing
   Broadcom SATA3 PHY driver
*) Add support for MIPI DPHYs in Exynos5420-compatible
   (5420, 5422 and 5800) and Exynos5433 SoCs
*) Add support for USB3 PHY on mt2701
*) Add extcon support for Renesas R-car USB2 PHY driver
*) Misc cleanups

Driver for Broadcom Northstar USB 2.0 PHY



Required properties:

- compatible: brcm,ns-usb2-phy

- reg: iomem address range of DMU (Device Management Unit)

- reg-names: "dmu", the only needed & supported reg right now

- clocks: USB PHY reference clock

- clock-names: "phy-ref-clk", the only needed & supported clock right now



To initialize USB 2.0 PHY driver needs to setup PLL correctly. To do this it

requires passing phandle to the USB PHY reference clock.



Example:

	usb2-phy {

		compatible = "brcm,ns-usb2-phy";

		reg = <0x1800c000 0x1000>;

		reg-names = "dmu";

		#phy-cells = <0>;

		clocks = <&genpll BCM_NSP_GENPLL_USB_PHY_REF_CLK>;

		clock-names = "phy-ref-clk";

	};
