The gadget driver may wait on the request completion when it sets the
USB_GADGET_DELAYED_STATUS. Make sure that the End Transfer command can
go through if the dwc->delayed_status is set so that the request can
complete. When the delayed_status is set, the Setup packet is already
processed, and the next phase should be either Data or Status. It's
unlikely that the host would cancel the control transfer and send a new
Setup packet during End Transfer command. But if that's the case, we can
try again when ep0state returns to EP0_SETUP_PHASE.

DWC3_EP_DELAYED_STOP is utilized to defer issuing the end transfer command
until the subsequent SETUP stage, in order to avoid end transfer timeouts.
During cable disconnect scenarios, __dwc3_gadget_ep_disable() is
responsible for ensuring endpoints have no active transfers pending. Since
dwc3_remove_request() can now exit early if the EP delayed stop is set,
avoid clearing all DEP flags, otherwise the transition back into the SETUP
stage won't issue an endxfer command.

During soft disconnect, EP0 events are expected to be handled in order to
allow the controller to successfully move into the halted state. Since
__dwc3_gadget_stop() is executed before polling, EP0 has been disabled, and
events are being blocked. Allow xfercomplete events to be handled, so that
cached SETUP packets can be read out from the internal controller memory.
Without doing so, it will lead to endxfer timeouts, which results to
controller halt failures.

If any function drivers request for a delayed status phase, this leads to a
SETUP transfer timeout error, since the function may take longer to process
the DATA stage. This eventually results in end transfer timeouts, as there
is a pending SETUP transaction.
In addition, allow the DWC3_EP_DELAY_STOP to be set for if there is a
delayed status requested. Ocasionally, a host may abort the current SETUP
transaction, by issuing a subsequent SETUP token. In those situations, it
would result in an endxfer timeout as well.

(cherry picked from commit e1ee843488)
There are some operations that need to be ignored if there is a soft
disconnect in progress. This is to avoid having a pending EP0 transfer in
progress while attempting to stop active transfers and halting the
controller.
There were several instances seen where a soft disconnect was able to occur
during early link negotiation, i.e. bus reset/conndone, which leads to the
conndone handler re-configuring EPs while attempting to halt the
controller, as DEP flags are cleared as part of the soft disconnect path.
ep0out: cmd 'Start New Configuration'
ep0out: cmd 'Set Endpoint Transfer Resource'
ep0in: cmd 'Set Endpoint Transfer Resource'
ep1out: cmd 'Set Endpoint Transfer Resource'
...
event (00030601): Suspend [U3]
event (00000101): Reset [U0]
ep0out: req ffffff87e5c9e100 length 0/0 zsI ==> 0
event (00000201): Connection Done [U0]
ep0out: cmd 'Start New Configuration'
ep0out: cmd 'Set Endpoint Transfer Resource'
In addition, if a soft disconnect occurs, EP0 events are still allowed to
process, however, it will stall/restart during the SETUP phase. The
host is still able to query for the DATA phase, leading to a
xfernotready(DATA) event. Since none of the SETUP transfer parameters are
populated, the xfernotready is treated as a "wrong direction" error,
leading to a duplicate stall/restart routine.
Add the proper softconnect/connected checks in sequences that are
potentially involved during soft disconnect processing.

(cherry picked from commit b44c0e7fef)
During a 3 stage SETUP transfer, if the host sends another SETUP token
before completing the status phase, it signifies that the host has aborted
the current control transfer. Currently, if a setup_packet_pending is
received, there are no subsequent calls to dwc3_ep0_out_start() to fetch
the new SETUP packet. This leads to a stall on EP0, as host does not
expect another STATUS phase as it has aborted the current transfer.
Fix this issue by explicitly stalling and restarting EP0, as well as
resetting the trb_enqueue indexes. (without this, there is a chance the
SETUP TRB is set up on trb_endqueue == 1)

According to the databook ep0 should be in setup phase during reset.
If host issues reset between control transfers, ep0 will be in an
invalid state. Fix this by issuing stall and restart on ep0 if it
is not in setup phase.
Also SW needs to complete pending control transfer and setup core for
next setup stage as per data book. Hence check ep0 state during reset
interrupt handling and make sure active transfers on ep0 out/in
endpoint are stopped by queuing ENDXFER command for that endpoint and
restart ep0 out again to receive next setup packet.

The driver shouldn't be able to issue End Transfer to the control
endpoint at anytime. Typically we should only do so in error cases such
as invalid/unexpected direction of Data Phase as described in the
control transfer flow of the programming guide. It _may_ end started
data phase during controller deinitialization from soft disconnect or
driver removal. However, that should not happen because the driver
should be maintained in EP0_SETUP_PHASE during driver tear-down. On
soft-connect, the controller should be reset from a soft-reset and there
should be no issue starting the control endpoint.

(cherry picked from commit 69e131d1ac)
The usb_ep_clear_halt() API can be called from the function driver, and
translates to dwc3_gadget_ep_set_halt(). This routine is shared with when
the host issues a clear feature ENDPOINT_HALT, and is differentiated by the
protocol argument. If the following sequence occurs, there can be a
situation where the delayed_status flag is improperly cleared for the wrong
SETUP transaction:
1. Vendor specific control transfer returns USB_GADGET_DELAYED_STATUS.
2. DWC3 gadget sets dwc->delayed_status to '1'.
3. Another function driver issues a usb_ep_clear_halt() call.
4. DWC3 gadget issues dwc3_stop_active_transfer() and sets
DWC3_EP_PENDING_CLEAR_STALL.
5. EP command complete interrupt triggers for the end transfer, and
dwc3_ep0_send_delayed_status() is allowed to run, as delayed_status
is '1' due to step#1.
6. STATUS phase is sent, and delayed_status is cleared.
7. Vendor specific control transfer is finished being handled, and issues
usb_composite_setup_continue(). This results in queuing of a data
phase.
Cache the protocol flag so that DWC3 gadget is aware of when the clear halt
is due to a SETUP request from the host versus when it is sourced from a
function driver. This allows for the EP command complete interrupt to know
if it needs to issue a delayed status phase.
