Here are some small USB fixes for 5.15-rc5 that resolve a number of
reported issues:
- gadget driver fixes
- xhci build warning fixes
- build configuration fix
- cdc-acm tty handling fixes
- cdc-wdm fix
- typec fixes
All of these have been in linux-next for a while with no reported

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.

Async feedback patches broke enumeration on Windows 10 previously fixed
by commit 789ea77310 ("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.

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:

[ 1.573973] 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.

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.

Some CP2102 do not support event-insertion mode but return no error when
attempting to enable it.
This means that any event escape characters in the input stream will not
be escaped by the device and consequently regular data may be
interpreted as escape sequences and be removed from the stream by the
driver.
The reporter's device has batch number DCL00X etched into it and as
discovered by the SHA2017 Badge team, counterfeit devices with that
marking can be detected by sending malformed vendor requests. [1][2]
Tests confirm that the possibly counterfeit CP2102 returns a single byte
in response to a malformed two-byte part-number request, while an
original CP2102 returns two bytes. Assume that every CP2102 that behaves
this way also does not support event-insertion mode (e.g. cannot report
parity errors).

For Isochronous endpoints, the SS companion descriptor's
wBytesPerInterval field is required to reserve bus time in order
to transmit the required payload during the service interval.
If left at 0, the UAC2 function is unable to transact data on its
playback or capture endpoints in SuperSpeed mode.
Since f_uac2 currently does not support any bursting this value can
be exactly equal to the calculated wMaxPacketSize.
Tested with Windows 10 as a host.

Set "HCD_FLAG_DEFER_RH_REGISTER" to hcd->flags in xhci_run() to defer
registering primary roothub in usb_add_hcd(). This will make sure both
primary roothub and secondary roothub will be registered along with the
second HCD. This is required for cold plugged USB devices to be detected
in certain PCIe USB cards (like Inateck USB card connected to AM64 EVM
or J7200 EVM).

It has been observed with certain PCIe USB cards (like Inateck connected
to AM64 EVM or J7200 EVM) that as soon as the primary roothub is
registered, port status change is handled even before xHC is running
leading to cold plug USB devices not detected. For such cases, registering
both the root hubs along with the second HCD is required. Add support for
deferring roothub registration in usb_add_hcd(), so that both primary and
secondary roothubs are registered along with the second HCD.

According USB spec each ISOC transaction should be performed in a
designated for that transaction interval. On bus errors or delays
in operating system scheduling of client software can result in no
packet being transferred for a (micro)frame. An error indication
should be returned as status to the client software in such a case.
Current implementation in case of missed/dropped interval send same
data in next possible interval instead of reporting missed isoc.
This fix complete requests with -ENODATA if interval elapsed.
HSOTG core in BDMA and Slave modes haven't HW support for
(micro)frames tracking, this is why SW should care about tracking
of (micro)frames. Because of that method and consider operating
system scheduling delays, added few additional checking's of elapsed
target (micro)frame:
1. Immediately before enabling EP to start transfer.
2. With any transfer completion interrupt.
3. With incomplete isoc in/out interrupt.
4. With EP disabled interrupt because of incomplete transfer.
5. With OUT token received while EP disabled interrupt (for OUT
transfers).
6. With NAK replied to IN token interrupt (for IN transfers).
As part of ISOC flow, additionally fixed 'current' and 'target' frame
calculation functions. In HS mode SOF limits provided by DSTS register
is 0x3fff, but in non HS mode this limit is 0x7ff.
Tested by internal tool which also using for dwc3 testing.

the phy init is invoked at every switch to device mode, but
its counter part de-init is missing, this causes the actual
phy init can not be done when we really want to re-init phy
like system resume, because the counter maintained by phy

That commit broke USB on all routers that have USB always powered on and
don't require toggling any GPIO. It's a majority of devices actually.
The original code worked and seemed safe: vcc GPIO is optional and
bcma_hci_platform_power_gpio() takes care of checking the pointer before
using it.

Setting EP_CMD_DRDY will be ignored by controller when
EP_STS_TRBERR is set. So, between these two instructions we have
a small time gap in which the EP_STSS_TRBERR can be set. In such case
the transfer will not start after setting doorbell.

Here is the big set of driver core patches for 5.15-rc1.
These do change a number of different things across different
subsystems, and because of that, there were 2 stable tags created that
might have already come into your tree from different pulls that did the
following
- changed the bus remove callback to return void
- sysfs iomem_get_mapping rework
The latter one will cause a tiny merge issue with your tree, as there
was a last-minute fix for this in 5.14 in your tree, but the fixup
should be "obvious". If you want me to provide a fixed merge for this,
please let me know.
Other than those two things, there's only a few small things in here:
- kernfs performance improvements for huge numbers of sysfs
users at once
- tiny api cleanups
- other minor changes
All of these have been in linux-next for a while with no reported
problems, other than the before-mentioned merge issue.

At least some PL2303GL have a bcdDevice of 0x405 instead of 0x100 as the
datasheet claims. Add it to the list of known release numbers for the
HXN (G) type.

The set/clear of the otg control values is done writing to
two different 16bit registers, however we setup the regmap
width for isp1760/61 to 32bit value bits.
So, just access the clear register address (0x376)as the high
part of the otg control register set (0x374), and write the
values in one go to make sure they get clear/set.

Instead of using the fields enum values to check interrupts
trigged, use the correct bit values.
