tx-fifo-resize is now added by default by the dwc3-qcom driver
to the SNPS DWC3 child node.
So, lets drop the tx-fifo-resize property from dwc3-qcom nodes
as having it there will cause the dwc3-qcom driver to error and
abort probe with:
[ 1.362938] dwc3-qcom 8af8800.usb: unable to add property

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.

The f_uac2 function fails to enumerate when connected in SuperSpeed
due to the feedback endpoint missing the companion descriptor.

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.

After we start to do core soft reset while usb role switch,
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
core is not 0. considering phy init is actually redundant for
role switch, so move out the phy init from core soft reset to
dwc3 core init where is the only place required.

This reverts commit f3de5d857b.
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.

For DEV_VER_V3 version there exist race condition between clearing
ep_sts.EP_STS_TRBERR and setting ep_cmd.EP_CMD_DRDY bit.
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.

This loop is supposed to loop until if reads something other than
CS_IDST or until it times out after 30,000 attempts. But because of
the || vs && bug, it will never time out and instead it will loop a

This bug is quite old but the code is only used in USB_DEVICE_TEST_MODE

To pick the change in:
7957d93bf3 ("block: add ioctl to read the disk sequence number")
It adds a new ioctl, but we are still not using that to generate tables
for 'perf trace', so no changes in tooling.
This silences this perf build warning:
Warning: Kernel ABI header at 'tools/include/uapi/linux/fs.h' differs from latest version at 'include/uapi/linux/fs.h'

To pick the changes in:
db243b7964 ("net/ipv4/ipv6: Replace one-element arraya with flexible-array members")
2d3e5caf96 ("net/ipv4: Replace one-element array with flexible-array member")
That don't result in any change in tooling, the structs changed remains
with the same layout.
This addresses this build warning:

Currently perf saves a build-id with size but old versions assumes the
size of 20. In case the build-id is less than 20 (like for MD5), it'd
fill the rest with 0s.
I saw a problem when old version of perf record saved a binary in the
build-id cache and new version of perf reads the data. The symbols
should be read from the build-id cache (as the path no longer has the
same binary) but it failed due to mismatch in the build-id.
symsrc__init: build id mismatch for /home/namhyung/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf.
The build-id event in the data has 20 byte build-ids, but it saw a
different size (16) when it reads the build-id of the elf file in the
build-id cache.

Let's fix this by allowing trailing zeros if the size is different.
