This reverts commit 796eed4b2342c9d6b26c958e92af91253a2390e1.
This change causes boot lockups when using "arlyprintk=xdbc" because
ktime can not be used at this point in time in the boot process. Also,
it is not needed for very small delays like this.

In current design, when the tcpm port is unregisterd, the kthread_worker
will be destroyed in the last step. Inside the kthread_destroy_worker(),
the worker will flush all the works and wait for them to end. However, if
one of the works calls hrtimer_start(), this hrtimer will be pending until
timeout even though tcpm port is removed. Once the hrtimer timeout, many
strange kernel dumps appear.
Thus, we can first complete kthread_destroy_worker(), then cancel all the
hrtimers. This will guarantee that no hrtimer is pending at the end.

When activate_stm_id_vb_detection is enabled, ID and Vbus detection relies
on sensing comparators. This detection needs time to stabilize.
A delay was already applied in dwc2_resume() when reactivating the
detection, but it wasn't done in dwc2_probe().
This patch adds delay after enabling STM ID/VBUS detection. Then, ID state
is good when initializing gadget and host, and avoid to get a wrong
Connector ID Status Change interrupt.

Szymon rightly pointed out that the previous check for the endpoint
direction in bRequestType was not looking at only the bit involved, but
rather the whole value. Normally this is ok, but for some request
types, bits other than bit 8 could be set and the check for the endpoint
length could not stall correctly.
Fix that up by only checking the single bit.

When generalising GPIO support and adding support for CP2102N, the GPIO
registration for some CP2105 devices accidentally broke. Specifically,
when all the pins of a port are in "modem" mode, and thus unavailable
for GPIO use, the GPIO chip would now be registered without having
initialised the number of GPIO lines. This would in turn be rejected by
gpiolib and some errors messages would be printed (but importantly probe
would still succeed).
Fix this by initialising the number of GPIO lines before registering the
GPIO chip.
Note that as for the other device types, and as when all CP2105 pins are
muxed for LED function, the GPIO chip is registered also when no pins
are available for GPIO use.

When listening for notifications through netlink of a new interface being
registered, sporadically, it is possible for the MAC to be read as zero.
The zero MAC address lasts a short period of time and then switches to a
valid random MAC address.
This causes problems for netd in Android, which assumes that the interface
is malfunctioning and will not use it.
In the good case we get this log:
InterfaceController::getCfg() ifName usb0
hwAddr 92:a8:f0:73:79:5b ipv4Addr 0.0.0.0 flags 0x1002
In the error case we get these logs:
InterfaceController::getCfg() ifName usb0
hwAddr 00:00:00:00:00:00 ipv4Addr 0.0.0.0 flags 0x1002
netd : interfaceGetCfg("usb0")
netd : interfaceSetCfg() -> ServiceSpecificException
(99, "[Cannot assign requested address] : ioctl() failed")
The reason for the issue is the order in which the interface is setup,
it is first registered through register_netdev() and after the MAC
address is set.
Fixed by first setting the MAC address of the net_device and after that
calling register_netdev().

Make xhci_disable_slot() synchronous, thus ensuring it, and
xhci_free_dev() calling it return after xHC controller completes
the disable slot command.
Otherwise the roothub and xHC host may runtime suspend, and clear the
command ring while the disable slot command is being processed.
This causes a command completion mismatch as the completion event can't
be mapped to the correct command.
Command ring gets out of sync and commands time out.
Driver finally assumes host is unresponsive and bails out.

When the xHCI is quirked with XHCI_RESET_ON_RESUME, runtime resume
routine also resets the controller.
This is bad for USB drivers without reset_resume callback, because
there's no subsequent call of usb_dev_complete() ->
usb_resume_complete() to force rebinding the driver to the device. For
instance, btusb device stops working after xHCI controller is runtime
resumed, if the controlled is quirked with XHCI_RESET_ON_RESUME.
So always take XHCI_RESET_ON_RESUME into account to solve the issue.

This reverts commit cefdd52fa0455c0555c30927386ee466a108b060.
On sc7180-trogdor class devices with 'fw_devlink=permissive' and KASAN
enabled, you'll see a Use-After-Free reported at bootup.
The root of the problem is that dwc3_qcom_of_register_core() is adding
a devm-allocated "tx-fifo-resize" property to its device tree node
using of_add_property().
The issue is that of_add_property() makes a _permanent_ addition to
the device tree that lasts until reboot. That means allocating memory
for the property using "devm" managed memory is a terrible idea since
that memory will be freed upon probe deferral or device unbinding.
Let's revert the patch since the system is still functional without
it. The fact that of_add_property() makes a permanent change is extra
fodder for those folks who were aruging that the device tree isn't
really the right way to pass information between parts of the
driver. It is an exercise left to the reader to submit a patch
re-adding the new feature in a way that makes everyone happier.

cgroup.h (therefore swap.h, therefore half of the universe)
includes bpf.h which in turn includes module.h and slab.h.
Since we're about to get rid of that dependency we need
to clean things up.
v2: drop the cpu.h include from cacheinfo.h, it's not necessary
and it makes riscv sensitive to ordering of include files.

In cdnsp_endpoint_init(), cdnsp_ring_alloc() is assigned to pep->ring
and there is a dereference of it in cdnsp_endpoint_init(), which could
lead to a NULL pointer dereference on failure of cdnsp_ring_alloc().
Fix this bug by adding a check of pep->ring.
This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.
Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.
Builds with CONFIG_USB_CDNSP_GADGET=y show no new warnings,
and our static analyzer no longer warns about this code.

Turns out some xHC controllers require all 64 bits in the CRCR register
to be written to execute a command abort.
The lower 32 bits containing the command abort bit is written first.
In case the command ring stops before we write the upper 32 bits then
hardware may use these upper bits to set the commnd ring dequeue pointer.
Solve this by making sure the upper 32 bits contain a valid command
ring dequeue pointer.
The original patch that only wrote the first 32 to stop the ring went
to stable, so this fix should go there as well.

xHC hardware can only have one slot in default state with address 0
waiting for a unique address at a time, otherwise "undefined behavior
may occur" according to xhci spec 5.4.3.4
The address0_mutex exists to prevent this across both xhci roothubs.
If hub_port_init() fails, it may unlock the mutex and exit with a xhci
slot in default state. If the other xhci roothub calls hub_port_init()
at this point we end up with two slots in default state.
Make sure the address0_mutex protects the slot default state across
hub_port_init() retries, until slot is addressed or disabled.
Note, one known minor case is not fixed by this patch.
If device needs to be reset during resume, but fails all hub_port_init()
retries in usb_reset_and_verify_device(), then it's possible the slot is
still left in default state when address0_mutex is unlocked.

The code that enables either BC_LVL or COMP_CHNG interrupt in tcpm_set_cc
wrongly assumes that the interrupt is unmasked by writing 1 to the apropriate
bit in the mask register. In fact, interrupts are enabled when the mask
is 0, so the tcpm_set_cc enables interrupt for COMP_CHNG when it expects
BC_LVL interrupt to be enabled.
This causes inability of the driver to recognize cable unplug events
in host mode (unplug is recognized only via a COMP_CHNG interrupt).
In device mode this bug was masked by simultaneous triggering of the VBUS
change interrupt, because of loss of VBUS when the port peer is providing
power.

A new commit in LLVM causes an error on the use of 'long double' when
'-mno-x87' is used, which the kernel does through an alias,
'-mno-80387' (see the LLVM commit below for more details around why it
does this).
drivers/usb/dwc2/hcd_queue.c:1744:25: error: expression requires 'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it
delay = ktime_set(0, DWC2_RETRY_WAIT_DELAY);
^
drivers/usb/dwc2/hcd_queue.c:62:34: note: expanded from macro 'DWC2_RETRY_WAIT_DELAY'
#define DWC2_RETRY_WAIT_DELAY (1 * 1E6L)
^
1 error generated.
This happens due to the use of a 'long double' literal. The 'E6' part of
'1E6L' causes the literal to be a 'double' then the 'L' suffix promotes
it to 'long double'.
There is no visible reason for a floating point value in this driver, as
the value is only used as a parameter to a function that expects an
integer type. Use NSEC_PER_MSEC, which is the same integer value as
'1E6L', to avoid changing functionality but fix the error.

The programming guide noted that the driver needs to verify if the link
state is in U0 before executing the Start Transfer command. If it's not
in U0, the driver needs to perform remote wakeup. This is not accurate.
If the link state is in U1/U2, then the controller will not respond to
link recovery request from DCTL.ULSTCHNGREQ. The Start Transfer command
will trigger a link recovery if it is in U1/U2. A clarification will be
added to the programming guide for all controller versions.
The current implementation shouldn't cause any functional issue. It may
occasionally report an invalid time out warning from failed link
recovery request. The driver will still go ahead with the Start Transfer
command if the remote wakeup fails. The new change only initiates remote
wakeup where it is needed, which is when the link state is in L1/L2/U3.

The End Transfer command from a stream endpoint will generate a NoStream

DWC3_EP_IGNORE_NEXT_NOSTREAM to track this prior to sending the command,
and it will be cleared on the next stream event. However, a stream event
may be generated before the End Transfer command completion and
prematurely clear the flag. Fix this by setting the flag on End Transfer
completion instead.
