Merge tag 'usb-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB/PHY updates from Greg KH:
 "Here is the big set of USB and PHY driver patches for 5.2-rc1

  There is the usual set of:

   - USB gadget updates

   - PHY driver updates and additions

   - USB serial driver updates and fixes

   - typec updates and new chips supported

   - mtu3 driver updates

   - xhci driver updates

   - other tiny driver updates

  Nothing really interesting, just constant forward progress.

  All of these have been in linux-next for a while with no reported
  issues. The usb-gadget and usb-serial trees were merged a bit "late",
  but both of them had been in linux-next before they got merged here
  last Friday"

+Amlogic Meson G12A DWC3 USB SoC Controller Glue
+
+The Amlogic G12A embeds a DWC3 USB IP Core configured for USB2 and USB3
+in host-only mode, and a DWC2 IP Core configured for USB2 peripheral mode
+only.
+
+A glue connects the DWC3 core to USB2 PHYs and optionnaly to an USB3 PHY.
+
+One of the USB2 PHY can be re-routed in peripheral mode to a DWC2 USB IP.
+
+The DWC3 Glue controls the PHY routing and power, an interrupt line is
+connected to the Glue to serve as OTG ID change detection.
+
+Required properties:
+- compatible:	Should be "amlogic,meson-g12a-usb-ctrl"
+- clocks:	a handle for the "USB" clock
+- resets:	a handle for the shared "USB" reset line
+- reg:		The base address and length of the registers
+- interrupts:	the interrupt specifier for the OTG detection
+- phys: 	handle to used PHYs on the system
+	- a <0> phandle can be used if a PHY is not used
+- phy-names:	names of the used PHYs on the system :
+	- "usb2-phy0" for USB2 PHY0 if USBHOST_A port is used
+	- "usb2-phy1" for USB2 PHY1 if USBOTG_B port is used
+	- "usb3-phy0" for USB3 PHY if USB3_0 is used
+- dr_mode:	should be "host", "peripheral", or "otg" depending on
+	the usage and configuration of the OTG Capable port.
+	- "host" and "peripheral" means a fixed Host or Device only connection
+	- "otg" means the port can be used as both Host or Device and
+	  be switched automatically using the OTG ID pin.
+
+Optional properties:
+- vbus-supply:	should be a phandle to the regulator controlling the VBUS
+		power supply when used in OTG switchable mode
+
+Required child nodes:
+
+A child node must exist to represent the core DWC3 IP block. The name of
+the node is not important. The content of the node is defined in dwc3.txt.
