Merge tag 'dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC DT updates from Olof Johansson:
 "DT and DT-conversion-related changes for various ARM platforms.  Most
  of these are to enable various devices on various boards, etc, and not
  necessarily worth enumerating.

  New boards and systems continue to come in as new devicetree files
  that don't require corresponding C changes any more, which is
  indicating that the system is starting to work fairly well.

  A few things worth pointing out:

   * ST Ericsson ux500 platforms have made the major push to move over
     to fully support the platform with DT
   * Renesas platforms continue their conversion over from legacy
     platform devices to DT-based for hardware description"

+TI Keystone USB PHY
+
+Required properties:
+ - compatible: should be "ti,keystone-usbphy".
+ - #address-cells, #size-cells : should be '1' if the device has sub-nodes
+   with 'reg' property.
+ - reg : Address and length of the usb phy control register set.
+
+The main purpose of this PHY driver is to enable the USB PHY reference clock
+gate on the Keystone SOC for both the USB2 and USB3 PHY. Otherwise it is just
+an NOP PHY driver.  Hence this node is referenced as both the usb2 and usb3
+phy node in the USB Glue layer driver node.

+TI Keystone Soc USB Controller

+DWC3 GLUE
+
+Required properties:
+ - compatible: should be "ti,keystone-dwc3".
+ - #address-cells, #size-cells : should be '1' if the device has sub-nodes
+   with 'reg' property.
+ - reg : Address and length of the register set for the USB subsystem on
+   the SOC.
+ - interrupts : The irq number of this device that is used to interrupt the
+   MPU.
+ - ranges: allows valid 1:1 translation between child's address space and
+   parent's address space.
+ - clocks: Clock IDs array as required by the controller.
+ - clock-names: names of clocks correseponding to IDs in the clock property.
+
+Sub-nodes:
+The dwc3 core should be added as subnode to Keystone DWC3 glue.
+- dwc3 :
+   The binding details of dwc3 can be found in:
