This time around we have a total of 57 non-merge commits. A list of
most important changes follows:

- Improvements to dwc3 tracing interface
- Initial dual-role support for dwc3
- Improvements to how we handle DMA resources in dwc3
- A new f_uac1 implementation which much more flexible
- Removal of AVR32 bits
- Improvements to f_mass_storage driver

Broadcom IPROC USB Device controller.



The device node is used for UDCs integrated into Broadcom's

iProc family (Northstar2, Cygnus) of SoCs'. The UDC is based

on Synopsys Designware Cores AHB Subsystem Device Controller

IP.



Required properties:

 - compatible: Add the compatibility strings for supported platforms.

   For Broadcom NS2 platform, add "brcm,ns2-udc","brcm,iproc-udc".

   For Broadcom Cygnus platform, add "brcm,cygnus-udc", "brcm,iproc-udc".

 - reg: Offset and length of UDC register set

 - interrupts: description of interrupt line

 - phys: phandle to phy node.



Example:

	udc_dwc: usb@664e0000 {

		compatible = "brcm,ns2-udc", "brcm,iproc-udc";

		reg = <0x664e0000 0x2000>;

		interrupts = <GIC_SPI 424 IRQ_TYPE_LEVEL_HIGH>;

		phys = <&usbdrd_phy>;
