As long as the START_TRANSFER command completes, it provides the
resource index of the endpoint. Use this when we need to issue
END_TRANSFER command to an isoc endpoint to retry with a new
XferNotReady event.

If dwc3 fails to issue START_TRANSFER/UPDATE_TRANSFER command, then we
should properly end an active transfer and give back all the started
requests. However if it's for an isoc endpoint, the failure maybe due to
bus-expiry status. In this case, don't give back the requests and wait
for the next retry.

Refactor the USB2 PHY init code patch to handle the Amlogic GXL/GXM
not having the PHY mode control registers in the Glue but in the PHY
registers.
The Amlogic GXL/GXM will call phy_set_mode() instead of programming the
PHY mode control registers, thus add two new callbacks to the SoC match
data.

On the Amlogic GXL/GXM SoCs, only the USB control registers are available,

Thus, handle the PHY mode registers in separate regmaps and prepare

set in the SoC match data.

Remove 2 unnecessary checks:
1) A request in the started_list must have its trb field set. So
checking for req->trb is unnecessary.
2) An endpoint must have started (and have not ended) for the request to
still be in the started_list. There's no point to check if the endpoint
is started. We had this check because previously the driver didn't
handle the endpoint's started/ended flags for END_TRANSFER command
properly. See commit 9f45581f5eec ("usb: dwc3: gadget: early giveback
if End Transfer already completed").

If a request is dequeued, the transfer is cancelled. Give back all
the started requests.
In most scenarios, the function driver dequeues all requests of a
transfer when there's a failure. If the function driver follows this,
then it's fine. If not, then we'd be skipping TRBs at different points
within the dequeue and enqueue pointers, making dequeue/enqueue pointers
useless. To enforce and make sure that we're properly skipping TRBs,
cancel all the started requests and give back all the cancelled requests
to the function drivers.

DWC3 must not issue CLEAR_STALL command to control endpoints. The
controller automatically clears the STALL when it receives the SETUP
token. Also, when the driver receives ClearFeature(halt_ep), DWC3 must
stop any active transfer from the endpoint and give back all the
requests to the function drivers.

This driver only creates a bunch of platform devices sharing resources
belonging to the PMC device. This is pretty much what MFD subsystem is
for so move the driver there, renaming it to intel_pmc_bxt.c which
should be more clear what it is.
MFD subsystem provides nice helper APIs for subdevice creation so
convert the driver to use those. Unfortunately the ACPI device includes
separate resources for most of the subdevices so we cannot simply call
mfd_add_devices() to create all of them but instead we need to call it
separately for each device.
The new MFD driver continues to expose two sysfs attributes that allow
userspace to send IPC commands to the PMC/SCU to avoid breaking any
existing applications that may use these. Generally this is bad idea so
document this in the ABI documentation.

Currently UCSI framework doesn't update USB data role when partner type

results into no USB host mode functionality. This is valid usecase where
user wants to use legacy type c power cable with type a female connector
to attach different USB devices like mouse, thumb drive etc. Hence update

Cyril Roelandt reports that his JMicron JMS566 USB-SATA bridge fails
to handle WRITE commands with the FUA bit set, even though it claims
to support FUA. (Oddly enough, a later version of the same bridge,
version 2.03 as opposed to 1.14, doesn't claim to support FUA. Also
oddly, the bridge _does_ support FUA when using the UAS transport
instead of the Bulk-Only transport -- but this device was blacklisted
for uas in commit bc3bdb12bbb3 ("usb-storage: Disable UAS on JMicron
SATA enclosure") for apparently unrelated reasons.)
This patch adds a usb-storage unusual_devs entry with the BROKEN_FUA
flag. This allows the bridge to work properly with usb-storage.

first for high speed devices")
Commit bd0e6c9614b9 ("usb: hub: try old enumeration scheme first for
high speed devices") changed the way the hub driver enumerates
high-speed devices. Instead of using the "new" enumeration scheme
first and switching to the "old" scheme if that doesn't work, we start
with the "old" scheme. In theory this is better because the "old"
scheme is slightly faster -- it involves resetting the device only
once instead of twice.
However, for a long time Windows used only the "new" scheme. Zeng Tao
said that Windows 8 and later use the "old" scheme for high-speed
devices, but apparently there are some devices that don't like it.
William Bader reports that the Ricoh webcam built into his Sony Vaio
laptop not only doesn't enumerate under the "old" scheme, it gets hung
up so badly that it won't then enumerate under the "new" scheme! Only
a cold reset will fix it.
Therefore we will revert the commit and go back to trying the "new"
scheme first for high-speed devices.
