Merge tag 'usb-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb into next

Pull USB driver updates from Greg KH:
 "Here is the big USB driver pull request for 3.16-rc1.

  Nothing huge here, but lots of little things in the USB core, and in
  lots of drivers.  Hopefully the USB power management will be work
  better now that it has been reworked to do per-port power control
  dynamically.  There's also a raft of gadget driver updates and fixes,
  CONFIG_USB_DEBUG is finally gone now that everything has been
  converted over to the dynamic debug inteface, the last hold-out
  drivers were cleaned up and the config option removed.  There were
  also other minor things all through the drivers/usb/ tree, the
  shortlog shows this pretty well.

  All have been in linux-next, including the very last patch, which came
  from linux-next to fix a build issue on some platforms"

+Samsung Exynos5 SoC series USB DRD PHY controller
+--------------------------------------------------
+
+Required properties:
+- compatible : Should be set to one of the following supported values:
+	- "samsung,exynos5250-usbdrd-phy" - for exynos5250 SoC,
+	- "samsung,exynos5420-usbdrd-phy" - for exynos5420 SoC.
+- reg : Register offset and length of USB DRD PHY register set;
+- clocks: Clock IDs array as required by the controller
+- clock-names: names of clocks correseponding to IDs in the clock property;
+	       Required clocks:
+	- phy: main PHY clock (same as USB DRD controller i.e. DWC3 IP clock),
+	       used for register access.
+	- ref: PHY's reference clock (usually crystal clock), used for
+	       PHY operations, associated by phy name. It is used to
+	       determine bit values for clock settings register.
+	       For Exynos5420 this is given as 'sclk_usbphy30' in CMU.
+- samsung,pmu-syscon: phandle for PMU system controller interface, used to
+		      control pmu registers for power isolation.
+- #phy-cells : from the generic PHY bindings, must be 1;
+
+For "samsung,exynos5250-usbdrd-phy" and "samsung,exynos5420-usbdrd-phy"
+compatible PHYs, the second cell in the PHY specifier identifies the
+PHY id, which is interpreted as follows:
+  0 - UTMI+ type phy,
+  1 - PIPE3 type phy,
+
+Example:
+	usbdrd_phy: usbphy@12100000 {
+		compatible = "samsung,exynos5250-usbdrd-phy";
+		reg = <0x12100000 0x100>;
+		clocks = <&clock 286>, <&clock 1>;
+		clock-names = "phy", "ref";
+		samsung,pmu-syscon = <&pmu_system_controller>;
+		#phy-cells = <1>;
+	};
+
+- aliases: For SoCs like Exynos5420 having multiple USB 3.0 DRD PHY controllers,
+	   'usbdrd_phy' nodes should have numbered alias in the aliases node,
+	   in the form of usbdrdphyN, N = 0, 1... (depending on number of
+	   controllers).
+Example:
+	aliases {
+		usbdrdphy0 = &usb3_phy0;
+		usbdrdphy1 = &usb3_phy1;
+	};
