Merge branch 'next' (accumulated 3.16 merge window patches) into master

Now that 3.15 is released, this merges the 'next' branch into 'master',
bringing us to the normal situation where my 'master' branch is the
merge window.

+Renesas AHB to PCI bridge
+-------------------------
+
+This is the bridge used internally to connect the USB controllers to the
+AHB. There is one bridge instance per USB port connected to the internal
+OHCI and EHCI controllers.
+
+Required properties:
+- compatible: "renesas,pci-r8a7790" for the R8A7790 SoC;
+	      "renesas,pci-r8a7791" for the R8A7791 SoC.
+- reg:	A list of physical regions to access the device: the first is
+	the operational registers for the OHCI/EHCI controllers and the
+	second is for the bridge configuration and control registers.
+- interrupts: interrupt for the device.
+- clocks: The reference to the device clock.
+- bus-range: The PCI bus number range; as this is a single bus, the range
+	     should be specified as the same value twice.
+- #address-cells: must be 3.
+- #size-cells: must be 2.
+- #interrupt-cells: must be 1.
+- interrupt-map: standard property used to define the mapping of the PCI
+  interrupts to the GIC interrupts.
+- interrupt-map-mask: standard property that helps to define the interrupt
+  mapping.
+
+Example SoC configuration:
+
+	pci0: pci@ee090000  {
+		compatible = "renesas,pci-r8a7790";
+		clocks = <&mstp7_clks R8A7790_CLK_EHCI>;
+		reg = <0x0 0xee090000 0x0 0xc00>,
+		      <0x0 0xee080000 0x0 0x1100>;
+		interrupts = <0 108 IRQ_TYPE_LEVEL_HIGH>;
+		status = "disabled";
+
+		bus-range = <0 0>;
+		#address-cells = <3>;
+		#size-cells = <2>;
+		#interrupt-cells = <1>;
+		interrupt-map-mask = <0xff00 0 0 0x7>;
+		interrupt-map = <0x0000 0 0 1 &gic 0 108 IRQ_TYPE_LEVEL_HIGH
+				 0x0800 0 0 1 &gic 0 108 IRQ_TYPE_LEVEL_HIGH
+				 0x1000 0 0 2 &gic 0 108 IRQ_TYPE_LEVEL_HIGH>;
+
+		pci@0,1 {
+			reg = <0x800 0 0 0 0>;
+			device_type = "pci";
+			phys = <&usbphy 0 0>;
+			phy-names = "usb";
+		};
+
+		pci@0,2 {
+			reg = <0x1000 0 0 0 0>;
+			device_type = "pci";
+			phys = <&usbphy 0 0>;
+			phy-names = "usb";
+		};
+	};
+
+Example board setup:
+
+&pci0 {
+	status = "okay";
+	pinctrl-0 = <&usb0_pins>;
+	pinctrl-names = "default";
+};
