94ad8aacbc ARM: omap1: move omap15xx local bus handling to usb.c
Commit 38225f2ef2f4 ("ARM/omap1: switch to use dma_direct_set_offset for
lbus DMA offsets") removed a lot of mach/memory.h, but left the USB
offset handling split into arch/arm/mach-omap1/usb.c and
drivers/usb/host/ohci-omap.c.

This can cause a randconfig build warning that now fails the build
with -Werror:

arch/arm/mach-omap1/usb.c:561:30: error: 'omap_1510_usb_ohci_nb' defined but not used [-Werror=unused-variable]
  561 | static struct notifier_block omap_1510_usb_ohci_nb = {
      |                              ^~~~~~~~~~~~~~~~~~~~~

Move it all into the platform file to get rid of the final
location that relies on mach/memory.h.

65a205e611 USB: cdc-acm: fix racy tty buffer accesses
A recent change that started reporting break events to the line
discipline caused the tty-buffer insertions to no longer be serialised
by inserting events also from the completion handler for the interrupt
endpoint.

Completion calls for distinct endpoints are not guaranteed to be
serialised. For example, in case a host-controller driver uses
bottom-half completion, the interrupt and bulk-in completion handlers
can end up running in parallel on two CPUs (high-and low-prio tasklets,
respectively) thereby breaking the tty layer's single producer
assumption.

Fix this by holding the read lock also when inserting characters from
the bulk endpoint.

0560c9c552 usb: gadget: f_uac2: fixed EP-IN wMaxPacketSize
Async feedback patches broke enumeration on Windows 10 previously fixed
by commit 789ea77310f0 ("usb: gadget: f_uac2: always increase endpoint
max_packet_size by one audio slot").

While the existing calculation for EP OUT capture for async mode yields
size+1 frame due to uac2_opts->fb_max > 0, playback side lost the +1
feature.  Therefore the +1 frame addition must be re-introduced for
playback. Win10 enumerates the device only when both EP IN and EP OUT
max packet sizes are (at least) +1 frame.

8253a34bfa usb: chipidea: ci_hdrc_imx: Also search for 'phys' phandle
When passing 'phys' in the devicetree to describe the USB PHY phandle
(which is the recommended way according to
Documentation/devicetree/bindings/usb/ci-hdrc-usb2.txt) the
following NULL pointer dereference is observed on i.MX7 and i.MX8MM:

[    1.489344] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000098

[    1.573973] lr : imx7d_charger_detection+0x22c/0x510

This happens because the charger functions check for the phy presence
inside the imx_usbmisc_data structure (data->usb_phy), but the chipidea
core populates the usb_phy passed via 'phys' inside 'struct ci_hdrc'
(ci->usb_phy) instead.

This causes the NULL pointer dereference inside imx7d_charger_detection().

Fix it by also searching for 'phys' in case 'fsl,usbphy' is not found.

Tested on a imx7s-warp board.

6d91017a29 usb: typec: tcpm: handle SRC_STARTUP state if cc changes
TCPM for DRP should do the same action as SRC_ATTACHED when cc changes in
SRC_STARTUP state. Otherwise, TCPM will transition to SRC_UNATTACHED state
which is not satisfied with the Type-C spec.

Per Type-C spec:
DRP port should move to Unattached.SNK instead of Unattached.SRC if sink
removed.

05300871c0 usb: typec: tcpci: don't handle vSafe0V event if it's not enabled
USB TCPCI Spec, 4.4.3 Mask Registers:
"A masked register will still indicate in the ALERT register, but shall
not set the Alert# pin low."

Thus, the Extended Status will still indicate in ALERT register if vSafe0V
is detected by TCPC even though being masked. In current code, howerer,
this event will not be handled in detection time. Rather it will be
handled when next ALERT event coming(CC evnet, PD event, etc).

Tcpm might transition to a wrong state in this situation. Thus, the vSafe0V
event should not be handled when it's masked.

72ee48ee89 usb: gadget: uvc: fix multiple opens
Currently, the UVC function is activated when open on the corresponding
v4l2 device is called.  On another open the activation of the function
fails since the deactivation counter in `usb_function_activate` equals
0. However the error is not returned to userspace since the open of the
v4l2 device is successful.

On a close the function is deactivated (since deactivation counter still
equals 0) and the video is disabled in `uvc_v4l2_release`, although the
UVC application potentially is streaming.

Move activation of UVC function to subscription on UVC_EVENT_SETUP
because there we can guarantee for a userspace application utilizing
UVC.  Block subscription on UVC_EVENT_SETUP while another application
already is subscribed to it, indicated by `bool func_connected` in
`struct uvc_device`.  Extend the `struct uvc_file_handle` with member
`bool is_uvc_app_handle` to tag it as the handle used by the userspace
UVC application.

With this a process is able to check capabilities of the v4l2 device
without deactivating the function for the actual UVC application.

846cbf98cb USB: EHCI: Improve port index sanitizing
Now that Kees Cook has added a definition for HCS_N_PORTS_MAX in
commit 72dd1843232c ("USB: EHCI: Add register array bounds to HCS
ports"), the code in ehci_hub_control() which sanitizes port index
values can be improved a little.

The idea behind this change is that it prevents a possible
out-of-bounds pointer computation, which the compiler might be able to
detect since the port_status[] array now has a fixed length rather
than a variable length.

The commit 217504a05532 ("usb: typec: ucsi: Work around PPM
losing change information") had solved this issue
previously, but in a really complex manner. The core issue
is that on some platforms the EC firmware does not interrupt
the driver on unplug event in some cases, mainly when the
cable is unplugged immediately after the plug-in.

From now on handling that problem by simply re-checking new
connections.

6cbe4b2d5a usb: typec: ucsi: Check the partner alt modes always if there is PD contract
UCSI does not tell the driver explicitly when the firmware
(PPM in UCSI lingo) has actually detected the partner
alternate modes, there is no specific change event for that.
That's why they have to be checked with any notification
that informs that PD contract with that partner has been
achieved.

Previously the alternate modes were checked always when the
firmware (PPM) informed that something with the partner had
changed, but on some platforms the EC firmware does not
generate separate events for generic partner changes at all.
On those platforms the EC firmware notifies the driver only
about connections, or separately about the PD contract if it
was not achieved soon enough after the initial connection
event.

The "poll worker" that is introduced here is first used for
checking partner alternate modes, but it can later be used
for any partner task that requires a separate job to be
scheduled to the connector specific workqueues.

The mechanism allows the partner device specific tasks to be
polling tasks and also delayed tasks if necessary.

By polling the partner alternate modes with this mechanism
the long command completion timeout value can be reduced
back to normal. The long command completion timeout was only
used to work around a problem on some platforms where the EC
firmware (PPM) didn't return BUSY even when it should with
the alt mode commands.

ce3e90d5a0 usb: misc: ehset: Workaround for "special" hubs
The USB2.0 spec chapter 11.24.2.13 says that the USB port which is going
under test needs to be put in suspend state before sending the test
command. Many hubs, don't enforce this precondition and they work fine
without this step. But there are some "special" hubs, which requires to
disable the port power before sending the test command.

Because the USB spec mention that the port should be suspended, also
do this step before sending the test command. This could rise the
problem with other hubs which are not compliant with the spec and the
test command will not work if the port is suspend. If such hubs are
found, a similar workaround like the disable part could be implemented
to skip the suspend port command.
