Pull USB / Thunderbolt updates from Greg KH:
 "Here is the large set of USB and Thunderbolt changes for 6.4-rc1.

  The "biggest" thing in here is the removal of two obsolete drivers,
  u132-hcd and ftdi-elan, making this a net-removal of code overall.

  Other than the driver removals, included in here are:

   - Thunderbolt updates for new hardware and features

   - xhci driver updates and fixes

   - dwc3 driver updates and fixes

   - gadget core and driver updates and features added

   - mtu3 driver updates

   - dwc2 driver fixes and updates

   - usb-serial driver updates

   - typec driver updates and fixes

   - platform remove callback changes

   - dts updates and conversions

   - other small changes

  All have been in linux-next for a while with no reported problems"

* USB2 ChipIdea USB controller for ci13xxx

Required properties:
- compatible: should be one of:
	"fsl,imx23-usb"
	"fsl,imx27-usb"
	"fsl,imx28-usb"
	"fsl,imx6q-usb"
	"fsl,imx6sl-usb"
	"fsl,imx6sx-usb"
	"fsl,imx6ul-usb"
	"fsl,imx7d-usb"
	"fsl,imx7ulp-usb"
	"fsl,imx8mm-usb"
	"lsi,zevio-usb"
	"qcom,ci-hdrc"
	"chipidea,usb2"
	"xlnx,zynq-usb-2.20a"
	"nvidia,tegra20-udc"
	"nvidia,tegra30-udc"
	"nvidia,tegra114-udc"
	"nvidia,tegra124-udc"
- reg: base address and length of the registers
- interrupts: interrupt for the USB controller

Recommended properies:
- phy_type: the type of the phy connected to the core. Should be one
  of "utmi", "utmi_wide", "ulpi", "serial" or "hsic". Without this
  property the PORTSC register won't be touched.
- dr_mode: One of "host", "peripheral" or "otg". Defaults to "otg"

Deprecated properties:
- usb-phy:      phandle for the PHY device. Use "phys" instead.
- fsl,usbphy: phandle of usb phy that connects to the port. Use "phys" instead.

Optional properties:
- clocks: reference to the USB clock
- phys: reference to the USB PHY
- phy-names: should be "usb-phy"
- vbus-supply: reference to the VBUS regulator
- maximum-speed: limit the maximum connection speed to "full-speed".
- tpl-support: TPL (Targeted Peripheral List) feature for targeted hosts
- itc-setting: interrupt threshold control register control, the setting
  should be aligned with ITC bits at register USBCMD.
- ahb-burst-config: it is vendor dependent, the required value should be
  aligned with AHBBRST at SBUSCFG, the range is from 0x0 to 0x7. This
  property is used to change AHB burst configuration, check the chipidea
  spec for meaning of each value. If this property is not existed, it
  will use the reset value.
- tx-burst-size-dword: it is vendor dependent, the tx burst size in dword
  (4 bytes), This register represents the maximum length of a the burst
  in 32-bit words while moving data from system memory to the USB
  bus, the value of this property will only take effect if property
  "ahb-burst-config" is set to 0, if this property is missing the reset
  default of the hardware implementation will be used.
- rx-burst-size-dword: it is vendor dependent, the rx burst size in dword
  (4 bytes), This register represents the maximum length of a the burst
  in 32-bit words while moving data from the USB bus to system memory,
  the value of this property will only take effect if property
  "ahb-burst-config" is set to 0, if this property is missing the reset
  default of the hardware implementation will be used.
- extcon: phandles to external connector devices. First phandle should point to
  external connector, which provide "USB" cable events, the second should point
  to external connector device, which provide "USB-HOST" cable events. If one
  of the external connector devices is not required, empty <0> phandle should
  be specified.
- phy-clkgate-delay-us: the delay time (us) between putting the PHY into
  low power mode and gating the PHY clock.
- non-zero-ttctrl-ttha: after setting this property, the value of register
  ttctrl.ttha will be 0x7f; if not, the value will be 0x0, this is the default
  value. It needs to be very carefully for setting this property, it is
  recommended that consult with your IC engineer before setting this value.
  On the most of chipidea platforms, the "usage_tt" flag at RTL is 0, so this
  property only affects siTD.
  If this property is not set, the max packet size is 1023 bytes, and if
  the total of packet size for pervious transactions are more than 256 bytes,
  it can't accept any transactions within this frame. The use case is single
  transaction, but higher frame rate.
  If this property is set, the max packet size is 188 bytes, it can handle
  more transactions than above case, it can accept transactions until it
  considers the left room size within frame is less than 188 bytes, software
  needs to make sure it does not send more than 90%
  maximum_periodic_data_per_frame. The use case is multiple transactions, but
  less frame rate.
- mux-controls: The mux control for toggling host/device output of this
  controller. It's expected that a mux state of 0 indicates device mode and a
  mux state of 1 indicates host mode.
- mux-control-names: Shall be "usb_switch" if mux-controls is specified.
- pinctrl-names: Names for optional pin modes in "default", "host", "device".
  In case of HSIC-mode, "idle" and "active" pin modes are mandatory. In this
  case, the "idle" state needs to pull down the data and strobe pin
  and the "active" state needs to pull up the strobe pin.
- pinctrl-n: alternate pin modes

i.mx specific properties
- fsl,usbmisc: phandler of non-core register device, with one
  argument that indicate usb controller index
- disable-over-current: disable over current detect
- over-current-active-low: over current signal polarity is active low.
- over-current-active-high: over current signal polarity is active high.
  It's recommended to specify the over current polarity.
- power-active-high: power signal polarity is active high
- external-vbus-divider: enables off-chip resistor divider for Vbus
- samsung,picophy-pre-emp-curr-control: HS Transmitter Pre-Emphasis Current
  Control. This signal controls the amount of current sourced to the
  USB_OTG*_DP and USB_OTG*_DN pins after a J-to-K or K-to-J transition.
  The range is from 0x0 to 0x3, the default value is 0x1.
  Details can refer to TXPREEMPAMPTUNE0 bits of USBNC_n_PHY_CFG1.
- samsung,picophy-dc-vol-level-adjust: HS DC Voltage Level Adjustment.
  Adjust the high-speed transmitter DC level voltage.
  The range is from 0x0 to 0xf, the default value is 0x3.
  Details can refer to TXVREFTUNE0 bits of USBNC_n_PHY_CFG1.

	usb@f7ed0000 {
