DWC3 controller on Qualcomm SOCs has a Qscratch wrapper.
Some of its uses are described below resulting in need to
have a separate glue driver instead of using dwc3-of-simple:
 - It exposes register interface to override vbus-override
   and lane0-pwr-present signals going to hardware. These
   must be updated in peripheral mode for DWC3 if vbus lines
   are not connected to hardware block. Otherwise RX termination
   in SS mode or DP pull-up is not applied by device controller.
 - pwr_events_irq_stat support to check if USB2 PHY is in L2 state
   before glue driver proceeds with suspend.
 - Support for wakeup interrupts lines that are asserted whenever
   there is any wakeup event on USB3 or USB2 bus.
 - Support to replace pip3 clock going to DWC3 with utmi clock
   for hardware configuration where SSPHY is not used with DWC3.

Update the source array (ecm_string_defs), every time before

The current frame_number is read from core for both
device and host modes. Reading of the current frame
number needs to be performed ASAP due to IRQ latency's.
This is why, it is moved to common interrupt handler.

Accordingly updated dwc2_gadget_target_frame_elapsed()
function which uses stored frame_number instead of
reading frame number.

In cases when target frame value is incremented
the frame_number is required to read again.

Dumping the registers via debugfs makes USB on Raspberry Pi completely

Changed existing two descriptor-chain flow to one chain.

In two-chain implementation BNA interrupt used for switching between
two chains. BNA interrupt asserted because of returning to
beginning of the chain based on L-bit of last descriptor.

Because of that we lose packets. This issue resolved by using one
desc-chain.

Removed all staff related to two desc-chain flow from
DDMA ISOC related functions.

Removed request length checking from dwc2_gadget_fill_isoc_desc()
function. Request length checking added to dwc2_hsotg_ep_queue()
function. If request length greater than descriptor limits then
request not added to queue. Additional checking done for High
Bandwidth ISOC OUT's which not supported by driver. In
dwc2_gadget_fill_isoc_desc() function also checked desc-chain
status (full or not) to avoid of reusing not yet processed
descriptors.

In dwc2_gadget_start_isoc_ddma() function creation of desc-chain
always started from descriptor 0. Before filling descriptors, they
were initialized by HOST BUSY status.

In dwc2_gadget_complete_isoc_request_ddma() added checking for
desc-chain rollover. Also added checking completion status.
Request completed successfully if DEV_DMA_STS is DEV_DMA_STS_SUCC,
otherwise complete with actual=0. For systems with high IRQ latency
added pointer compl_desc to next descriptor to be completed by
XferCompl interrupt. This pointer replace descriptor index calculation
based on DxEPDMA register. On descriptor completion interrupt
processing all descriptors starting from compl_desc till descriptor
which Buffer Status field not equal DMA_DONE status.

Actually removed dwc2_gadget_start_next_isoc_ddma() function because
now driver use only one desc-chain and instead that function added
dwc2_gadget_handle_isoc_bna() function for handling BNA interrupts.

Handling BNA interrupt done by flushing TxFIFOs for OUT EPs,
completing request with actual=0 and resetting desc-chain number and
target frame to initial values for restarting transfers.

On handling NAK request completed with actual=0. Incremented target
frame to allow fill desc chain and start transfers.
In DDMA mode avoided of frame number incrementing, because tracking
of frame number performed in dwc2_gadget_fill_isoc_desc() function.

When core assert XferCompl along with BNA, we should ignore XferCompl
in dwc2_hsotg_epint() function.

On BNA interrupt replaced dwc2_gadget_start_next_isoc_ddma() by above
mentioned BNA handler.

In dwc2_hsotg_ep_enable() function added sanity check of bInterval
for ISOC IN in DDMA mode, because HW doesn't supported EP's with
bInterval more than 10 and check for mc for ISOC OUT transfers,
because core doesn't support high bandwidth transfers.

The root cause is as the following:
When the xHCI driver set PORT_POWER of the OTG port, and if both
IDPIN and VBUS_VALID are high at the same time, the MTU3 controller
will set SESSION and pull up DP, so the Win7 can detect existence
of USB device, but if the mtu3 driver can't switch to device mode

Since the user could take a long time to release the

The Aspeed BMC SoCs support a "virtual hub" function. It provides some
HW support for a top-level USB2 hub behind which sit 5 gadget "ports".

This driver adds support for the full functionality, emulating the
hub standard requests and exposing 5 UDC gadget drivers corresponding
to the ports.

The hub itself has HW provided dedicated EP0 and EP1 (the latter for
hub interrupts). It also has dedicated EP0s for each function. For
other endpoints, there's a pool of 15 "generic" endpoints that are
shared among the ports.

The driver relies on my previous patch adding a "dispose" EP op to
handle EP allocation between ports. EPs are allocated from the shared
pool in the UDC "match_ep" callback and assigned to the UDC instance
(added to the gadget ep_list).

When the composite driver gets unbound, the new hook will allow the UDC
to clean things up and return those EPs to the shared pool.

Pull /dev/random fixes from Ted Ts'o:
 "Fix some bugs in the /dev/random driver which causes getrandom(2) to
  unblock earlier than designed.

  Thanks to Jann Horn from Google's Project Zero for pointing this out
  to me"

Pull libnvdimm fixes from Dan Williams:
 "A regression fix, new unit test infrastructure and a build fix:

   - Regression fix addressing support for the new NVDIMM label storage
     area access commands (_LSI, _LSR, and _LSW).

     The Intel specific version of these commands communicated the
     "Device Locked" status on the label-storage-information command.

     However, these new commands (standardized in ACPI 6.2) communicate
     the "Device Locked" status on the label-storage-read command, and
     the driver was missing the indication.

     Reading from locked persistent memory is similar to reading
     unmapped PCI memory space, returns all 1's.

   - Unit test infrastructure is added to regression test the "Device
     Locked" detection failure.

   - A build fix is included to allow the "of_pmem" driver to be built
     as a module and translate an Open Firmware described device to its
     local numa node"
