  Lots of USB changes in here, primarily in these areas:

   - typec updates and new drivers

   - new PHY drivers

   - dwc2 driver updates and additions (this old core keeps getting
     added to new devices.)

   - usbtmc major update based on the industry group coming together and
     working to add new features and performance to the driver.

   - USB gadget additions for new features

   - USB gadget configfs updates

   - chipidea driver updates

   - other USB gadget updates

   - USB serial driver updates

   - renesas driver updates

   - xhci driver updates

Faraday FOTG Host controller
This OTG-capable USB host controller is found in Cortina Systems
Gemini and other SoC products.
Required properties:
- compatible: should be one of:
"faraday,fotg210"
"cortina,gemini-usb", "faraday,fotg210"
- reg: should contain one register range i.e. start and length
- interrupts: description of the interrupt line
Optional properties:
- clocks: should contain the IP block clock
- clock-names: should be "PCLK" for the IP block clock
Required properties for "cortina,gemini-usb" compatible:
- syscon: a phandle to the system controller to access PHY registers
Optional properties for "cortina,gemini-usb" compatible:
- cortina,gemini-mini-b: boolean property that indicates that a Mini-B
OTG connector is in use
- wakeup-source: see power/wakeup-source.txt
Example for Gemini:
usb@68000000 {
compatible = "cortina,gemini-usb", "faraday,fotg210";
reg = <0x68000000 0x1000>;
interrupts = <10 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&cc 12>;
clock-names = "PCLK";
syscon = <&syscon>;
wakeup-source;
};
