Two kerneldoc comments in gadget.c have excess function parameter description or wrong
prototype name and one kerneldoc comment in core.c has an excess function parameter
description, resulting in these three doc-build warnings:
1. ./drivers/usb/dwc3/gadget.c:675: warning: Excess function parameter
'nfifos' description in 'dwc3_gadget_calc_tx_fifo_size'
2. ./drivers/usb/dwc3/gadget.c:700: warning: expecting prototype for
dwc3_gadget_clear_tx_fifo_size(). Prototype was for dwc3_gadget_clear_tx_fifos()
instead
3. ./drivers/usb/dwc3/core.c:347: warning: Excess function parameter 'ref_clk_per'
description in 'dwc3_ref_clk_period'
Fix the warnings by correcting the prototype name and removing excess parameter descriptions.

Since commit ae8709b296d8 ("USB: core: Make do_proc_control() and
do_proc_bulk() killable") if a device has the USB_QUIRK_DELAY_CTRL_MSG
quirk set, it will temporarily block all other URBs (e.g. interrupts)
while sleeping due to a control.
This results in noticeable delays when, for example, a userspace usbfs
application is sending URB interrupts at a high rate to a keyboard and
simultaneously updates the lock indicators using controls. Interrupts
with direction set to IN are also affected by this, meaning that
delivery of HID reports (containing scancodes) to the usbfs application
is delayed as well.
This patch fixes the regression by calling msleep() while the device
mutex is unlocked, as was the case originally with usb_control_msg().

If the PHY controller node has a "port" dwc3 tries to find an
extcon device even when "usb-role-switch" is present. This happens
because dwc3_get_extcon() sees that "port" node and then calls
extcon_find_edev_by_node() which will always return EPROBE_DEFER
in that case.
On the other hand, even if an extcon was present and dwc3_get_extcon()
was successful it would still be ignored in favor of "usb-role-switch".
Let's just first check if "usb-role-switch" is configured in the device
tree and directly use it instead and only try to look for an extcon
device otherwise.

Issue description:
When an OTG port has been switched to device role and then switch back
to host role again, the USB 3.0 Host (XHCI) will not be able to detect
"plug in event of a connected USB 2.0/1.0 ((Highspeed and Fullspeed)
devices until system reboot.
Root cause and Solution:
There is a condition checking flag "ssusb->otg_switch.is_u3_drd" in
toggle_opstate(). At the end of role switch procedure, toggle_opstate()
will be called to set DC_SESSION and SOFT_CONN bit. If "is_u3_drd" was
set and switched the role to USB host 3.0, bit DC_SESSION and SOFT_CONN
will be skipped hence caused the port cannot detect connected USB 2.0
(Highspeed and Fullspeed) devices. Simply remove the condition check to
solve this issue.

It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ)
for requesting IRQ's resources any more, as they can be not ready yet in
case of DT-booting.
platform_get_irq() instead is a recommended way for getting IRQ even if
it was not retrieved earlier.
It also makes code simpler because we're getting "int" value right away
and no conversion from resource to int is required.

The function documentation of usb_set_configuration says that its
callers should hold the device lock. This lock is held for all
callsites except tweak_set_configuration_cmd. The code path can be
executed for example when attaching a remote USB device.
The solution is to surround the call by the device lock.
This bug was found using my experimental own-developed static analysis
tool, which reported the missing lock on v5.17.2. I manually verified
this bug report by doing code review as well. I runtime checked that
the required lock is not held. I compiled and runtime tested this on
x86_64 with a USB mouse. After applying this patch, my analyser no
longer reports this potential bug.

Commit 33fb697ec7e5 ("usb: dwc3: Get clocks individually") moved from
the clk_bulk api to individual clocks, following the snps,dwc3.yaml
dt-binding for clock names.
Unfortunately the rk3328 (and upcoming rk356x support) use the
rockchip,dwc3.yaml which has different clock names, which are common on
devices using the glue layer.
The rk3328 does not use a glue layer, but attaches directly to the dwc3
core driver.
The offending patch series failed to account for this, thus dwc3 was
broken on rk3328.
To retain backwards compatibility with rk3328 device trees we must also
check for the alternate clock names.

In zhaoxin platform, some ehci projects will latch a wakeup signal
internal when plug in a device on port during system S0. This wakeup
signal will turn on when ehci runtime suspend, which will trigger a
system control interrupt that will resume ehci back to D0. As no
device connect, ehci will be set to runtime suspend and turn on the
internal latched wakeup signal again. It will cause a suspend-resume
loop and generate system control interrupt continuously.
Fixed this issue by clear wakeup signal latched in ehci internal when
ehci resume callback is called.

The sizeof(struct whitehat_dr_info) can be 4 bytes under CONFIG_AEABI=n
due to "-mabi=apcs-gnu", even though it has a single u8:
whiteheat_private {
__u8 mcr; /* 0 1 */
/* size: 4, cachelines: 1, members: 1 */
/* padding: 3 */
/* last cacheline: 4 bytes */
};
The result is technically harmless, as both the source and the
destinations are currently the same allocation size (4 bytes) and don't
use their padding, but if anything were to ever be added after the
"mcr" member in "struct whiteheat_private", it would be overwritten. The
structs both have a single u8 "mcr" member, but are 4 bytes in padded
size. The memcpy() destination was explicitly targeting the u8 member
(size 1) with the length of the whole structure (size 4), triggering
the memcpy buffer overflow warning:

The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:
- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros
Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.
linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

During the uvcg_video_pump() process, if an error occurs and
uvcg_queue_cancel() is called, the buffer queue will be cleared out, but
the current marker (queue->buf_used) of the active buffer (no longer
active) is not reset. On the next iteration of uvcg_video_pump() the
stale buf_used count will be used and the logic of min((unsigned
int)len, buf->bytesused - queue->buf_used) may incorrectly calculate a
nbytes size, causing an invalid memory access.

Path fixes bug which occurs during resetting endpoint in
__cdns3_gadget_ep_clear_halt function. During resetting endpoint
controller will change HW/DMA owned TRB. It set Abort flag in
trb->control and will change trb->length field. If driver want
to use the aborted trb it must update the changed field in
TRB.

The first U3 wake signal by the host may be lost if the USB 3 connection is
tunneled over USB4, with a runtime suspended USB4 host, and firmware
implemented connection manager.
Specs state the host must wait 100ms (tU3WakeupRetryDelay) before
resending a U3 wake signal if device doesn't respond, leading to U3 -> U0
link transition times around 270ms in the tunneled case.
Fixes: 0200b9f790b0 ("xhci: Wait until link state trainsits to U0 after setting USB_SS_PORT_LS_U0")
