Merge tag 'usb-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB / PHY updates from Greg KH:
 "Here are the big set of USB and PHY driver patches for 5.7-rc1.

  Nothing huge here, some new PHY drivers, loads of USB gadget fixes and
  updates, xhci updates, usb-serial driver updates and new device ids,
  and other minor things. Full details in the shortlog.

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

-DWC3 PHY nodes are defined to describe on-chip Synopsis Physical layer
-controllers.  Each DWC3 PHY controller should have its own node.
-
-Required properties:
-- compatible: should contain one of the following:
-	- "qcom,dwc3-hs-usb-phy" for High Speed Synopsis PHY controller

-- reg: offset and length of the DWC3 PHY controller register set
-- #phy-cells: must be zero
-- clocks: a list of phandles and clock-specifier pairs, one for each entry in
-  clock-names.
-- clock-names: Should contain "ref" for the PHY reference clock
-
-Optional clocks:

+==============
+USB Raw Gadget
+==============
+
+USB Raw Gadget is a kernel module that provides a userspace interface for
+the USB Gadget subsystem. Essentially it allows to emulate USB devices
+from userspace. Enabled with CONFIG_USB_RAW_GADGET. Raw Gadget is
+currently a strictly debugging feature and shouldn't be used in
+production, use GadgetFS instead.
+
+Comparison to GadgetFS
+~~~~~~~~~~~~~~~~~~~~~~
+
+Raw Gadget is similar to GadgetFS, but provides a more low-level and
+direct access to the USB Gadget layer for the userspace. The key
+differences are:
+
+1. Every USB request is passed to the userspace to get a response, while
+   GadgetFS responds to some USB requests internally based on the provided
+   descriptors. However note, that the UDC driver might respond to some
+   requests on its own and never forward them to the Gadget layer.
+
+2. GadgetFS performs some sanity checks on the provided USB descriptors,
+   while Raw Gadget allows you to provide arbitrary data as responses to
+   USB requests.
+
+3. Raw Gadget provides a way to select a UDC device/driver to bind to,
+   while GadgetFS currently binds to the first available UDC.
+
+4. Raw Gadget uses predictable endpoint names (handles) across different
+   UDCs (as long as UDCs have enough endpoints of each required transfer
+   type).
+
+5. Raw Gadget has ioctl-based interface instead of a filesystem-based one.
+
+Userspace interface
+~~~~~~~~~~~~~~~~~~~
+
+To create a Raw Gadget instance open /dev/raw-gadget. Multiple raw-gadget
+instances (bound to different UDCs) can be used at the same time. The
+interaction with the opened file happens through the ioctl() calls, see
+comments in include/uapi/linux/usb/raw_gadget.h for details.
+
+The typical usage of Raw Gadget looks like:
+
+1. Open Raw Gadget instance via /dev/raw-gadget.
+2. Initialize the instance via USB_RAW_IOCTL_INIT.
+3. Launch the instance with USB_RAW_IOCTL_RUN.
+4. In a loop issue USB_RAW_IOCTL_EVENT_FETCH calls to receive events from
+   Raw Gadget and react to those depending on what kind of USB device
+   needs to be emulated.
+
+Potential future improvements
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- Implement ioctl's for setting/clearing halt status on endpoints.
+
+- Reporting more events (suspend, resume, etc.) through
+  USB_RAW_IOCTL_EVENT_FETCH.
+
+- Support O_NONBLOCK I/O.
