Port partner could send PR_SWAP/DR_SWAP/VCONN_SWAP/Request just after it
enters Ready states. This will cause conficts if the port is going to
send DISC_IDENT in the Ready states of TCPM. Set a flag indicating that
the state machine is processing VDM and respond Wait messages until the
VDM state machine stops.

759f5d09e9 FROMGIT: usb: typec: tcpm: Protocol Error handling 
PD3.0 Spec 6.8.1 describes how to handle Protocol Error. There are
general rules defined in Table 6-61 which regulate incoming Message
handling. If the incoming Message is unexpected, unsupported, or
unrecognized, Protocol Error occurs. Follow the rules to handle these
situations. Also consider PD2.0 connection (PD2.0 Spec Table 6-36) for
backward compatibilities.

To know the types of AMS in all the recipient's states, identify those
AMS who are initiated by the port partner but not yet recorded in the
current code.

Besides, introduce a new state CHUNK_NOT_SUPP to delay the NOT_SUPPORTED
message after receiving a chunked message.

This patch provides the implementation of Collision Avoidance introduced
in PD3.0. The start of each Atomic Message Sequence (AMS) initiated by
the port will be denied if the current AMS is not interruptible. The
Source port will set the CC to SinkTxNG if it is going to initiate an
AMS, and SinkTxOk otherwise. Meanwhile, any AMS initiated by a Sink port
will be denied in TCPM if the port partner (Source) sets SinkTxNG except
for HARD_RESET and SOFT_RESET.

dd09232ee5 FROMGIT: ufs: introduce a quirk to allow only page-aligned sg entries 
Some SoCs could require one scatterlist entry for smaller than
page size, i.e. 4KB. For the cases of dispatching commands
with more than one scatterlist entry and under 4KB size,
They could behave as follows:

Given that a command to read something
from device is dispatched with two scatterlist entries that
are named AAA and BBB. After dispatching, host builds two PRDT
entries and during transmission, device sends just one DATA IN
because device doesn't care on host dma. The host then tranfers
the whole data from start address of the area named AAA.
In consequence, the area that follows AAA would be corrupted.

    |<------------->|
    +-------+------------         +-------+
    +  AAA  + (corrupted)   ...   +  BBB  +
    +-------+------------         +-------+

In this case, you need to force an alignment with page size for
sg entries.

d918b40977 FROMGIT: usb: gadget: u_audio: Free requests only after callback 
As per the kernel doc for usb_ep_dequeue(), it states that "this
routine is asynchronous, that is, it may return before the completion
routine runs". And indeed since v5.0 the dwc3 gadget driver updated
its behavior to place dequeued requests on to a cancelled list to be
given back later after the endpoint is stopped.

The free_ep() was incorrectly assuming that a request was ready to
be freed after calling dequeue which results in a use-after-free
in dwc3 when it traverses its cancelled list. Fix this by moving
the usb_ep_free_request() call to the callback itself in case the
ep is disabled.

Use SuperSpeed Plus sublink speed macros to fill the BOS descriptor
sublink speed attributes in the composite driver. They're
self-documented so we can remove some of the comments, and this helps
with readability by removing the magic numbers.

899051f22f FROMGIT: usb: dwc3: pci: ID for Tiger Lake CPU 
Tiger Lake SOC (the versions of it that have integrated USB4
controller) may have two DWC3 controllers. One is part of
the PCH (Platform Controller Hub, i.e. the chipset) as
usual, and the other is inside the actual CPU block.

On all Intel platforms that have the two separate DWC3
controllers, the one inside the CPU handles USB3 and only
USB3 traffic, while the PCH version handles USB2 and USB2
alone. The reason for splitting the two busses like this is
to allow easy USB3 tunneling over USB4 connections. As USB2
is not tunneled over USB4, it has dedicated USB controllers
(both xHCI and DWC3).

The usb_f_printer gadget driver uses a default q_len value of *0* which prevents
any IO from occurring.  Moreover, once the driver is instantiated it is
impossible to change the q_len value.

The following patch uses a default q_len value of 10 which matches the legacy
g_printer gadget driver.  This minimizes the possibility that you end up with a
non-working printer gadget.  It is still possible to set the q_len to a
different value using the configfs path of the same name.

e2724acdda FROMGIT: usb: dwc3: gadget: Introduce a DWC3 VBUS draw callback 
Some devices support charging while in device mode.  In these situations,
the USB gadget will notify the DWC3 gadget driver to modify the current
based on the enumeration and device state.  The usb_phy_set_power() API
will allow external charger entities to adjust the charge current through
the notifier block.
