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.

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.

The dwc3 core binding specifies one reset.

However some variants of the hardware may have more. Previously
this was handled by using the dwc3-of-simple glue driver, but
that resulted in a proliferation of bindings for for every
variant, when the only difference was the clocks and resets
lists.

So this patch reworks the reading of the resets to fetch all the
resets specified in the dts together.

This patch was recommended by Rob Herring <robh@kernel.org>
as an alternative to creating multiple bindings for each variant
of hardware.

The dwc3 core binding specifies three clocks:

which are all controlled in the driver together.

However some variants of the hardware my not have all three
clks, or some may have more. Usually this was handled by using
the dwc3-of-simple glue driver, but that resulted in a

In certain circumstances, the XHCI SuperSpeed instance in park mode
can fail to recover, thus on Amlogic G12A/G12B/SM1 SoCs when there is high
load on the single XHCI SuperSpeed instance, the controller can crash like:
 xhci-hcd xhci-hcd.0.auto: xHCI host not responding to stop endpoint command.
 xhci-hcd xhci-hcd.0.auto: Host halt failed, -110
 xhci-hcd xhci-hcd.0.auto: xHCI host controller not responding, assume dead
 xhci-hcd xhci-hcd.0.auto: xHCI host not responding to stop endpoint command.
 hub 2-1.1:1.0: hub_ext_port_status failed (err = -22)
 xhci-hcd xhci-hcd.0.auto: HC died; cleaning up
 usb 2-1.1-port1: cannot reset (err = -22)

Setting the PARKMODE_DISABLE_SS bit in the DWC3_USB3_GUCTL1 mitigates
the issue. The bit is described as :
"When this bit is set to '1' all SS bus instances in park mode are disabled"

Synopsys explains:
The GUCTL1.PARKMODE_DISABLE_SS is only available in
dwc_usb3 controller running in host mode.
This should not be set for other IPs.
This can be disabled by default based on IP, but I recommend to have a
property to enable this feature for devices that need this.

Pull ARM SoC fixes from Olof Johansson:
 "We've been accruing these for a couple of weeks, so the batch is a bit
  bigger than usual.

  Largest delta is due to a led-bl driver that is added -- there was a
  miscommunication before the merge window and the driver didn't make it
  in. Due to this, the platforms needing it regressed. At this point, it
  seemed easier to add the new driver than unwind the changes.

  Besides that, there are a handful of various fixes:

   - AMD tee memory leak fix

   - A handful of fixlets for i.MX SCU communication

   - A few maintainers woke up and realized DEBUG_FS had been missing
     for a while, so a few updates of that.
