The host needs to tell the device the exit latencies using the SET_SEL
request before device initiated link powermanagement can be enabled.
The exit latency values do not change after enumeration, it's enough
to set them once. So do like Windows 10 and issue the SET_SEL request
once just before setting the configuration.
This is also the sequence described in USB 3.2 specs "9.1.2 Bus
enumeration". SET_SEL is issued once before the Set Configuration
request, and won't be cleared by the Set Configuration,
Set Interface or ClearFeature (STALL) requests.
Only warm reset, hot reset, set Address 0 clears the exit latencies.
See USB 3.2 section 9.4.14 Table 9-10 Device parameters and events
Add udev->lpm_devinit_allow, and set it if SET_SEL was successful.
If not set, then don't try to enable device initiated LPM
We used to issue a SET_SEL request every time lpm is enabled for either
U1 or U2 link states, meaning a SET_SEL was issued twice after every
Set Configuration and Set Interface requests, easily accumulating to
over 15 SET_SEL requets during a USB3 webcam enumeration.

All the USB Type-C Connector Class devices are protected, so
the drivers can not directly access them. This will adds a
few helpers that can be used to link the ports and partners
to the correct USB Power Delivery objects.
For ports a new optional sysfs attribute file is also added
that can be used to select the USB Power Delivery
capabilities that the port will advertise to the partner.

Introducing a small device class for USB Power Delivery.
The idea with it is that we do not mix any more USB Power
Delivery information into the USB Type-C connectors only.
This separation will make it possible to register USB Power
Delivery devices also from other places, for example from
USB Type-C Bridges (see USB Type-C Bridge Specification).
The device class will not always deal with only the messages
and objects that were negotiated with the partner, but
instead messages and objects that can be used in the
negotiation. That allows the USB PD devices to be shared and
reconfigured. The ports can decide which objects are to be
advertised to the partner before the contract is negotiated.
It is also possible to allow the user space to make that
decision if needed.

In some cases the port of an hub needs to be disabled or switched off
and on again. E.g. when the connected device needs to be re-enumerated.
Or it needs to be explicitly disabled while the rest of the usb tree
stays working.
For this purpose this patch adds an sysfs switch to enable/disable the
port on any hub. In the case the hub is supporting power switching, the
power line will be disabled to the connected device.
When the port gets disabled, the associated device gets disconnected and
removed from the logical usb tree. No further device will be enumerated
on that port until the port gets enabled again.

The current limitation of possible number of requests being handled is
dependent on the gadget speed. It makes more sense to depend on the
typical frame size when calculating the number of requests. This patch
is changing this and is using the previous limits as boundaries for
reasonable minimum and maximum number of requests.
For a 1080p jpeg encoded video stream with a maximum imagesize of
e.g. 800kB with a maxburst of 8 and an multiplier of 1 the resulting
number of requests is calculated to 49.

Currently the VBUS/ID detection interrupts are disabled during system
suspend. So the USB cable connect/disconnect event can't wakeup the
system from low power mode. To allow this, we keep these interrupts
enabled and configure them as wakeup capable. This behavior can be
controlled through device wakeup source policy by the user space.

This code does:
spin_unlock_irq(&udc->ud.lock);
spin_unlock_irqrestore(&udc->lock, flags);
which does not make sense. In theory, the first unlock could enable
IRQs and then the second _irqrestore could disable them again. There
would be a brief momemt where IRQs were enabled improperly.
In real life, however, this function is always called with IRQs enabled
and the bug does not affect runtime.

It generally doesn't make sense to use _irq() and _irqsave() in the same
function because either some of the callers have disabled IRQs or they
haven't. In this case, the v_recv_cmd_submit() appears to always be
called with IRQs enabled so the code works fine. That means I could
convert it to either _irq() or _irqsave() but I chose to use _irqsave()
because it's more conservative and easier to review.

Some SoC(e.g NXP imx8MQ) may have a wrong default power down scale
setting so need init it to be the correct value, the power down
scale setting description in DWC3 databook:
Power Down Scale (PwrDnScale)
The USB3 suspend_clk input replaces pipe3_rx_pclk as a clock source to
a small part of the USB3 core that operates when the SS PHY is in its
lowest power (P3) state, and therefore does not provide a clock.
The Power Down Scale field specifies how many suspend_clk periods fit
into a 16 kHz clock period. When performing the division, round up the
remainder.
For example, when using an 8-bit/16-bit/32-bit PHY and 25-MHz Suspend
clock,
Power Down Scale = 25000 kHz/16 kHz = 13'd1563 (rounder up)
So use the suspend clock rate to calculate it.

Pull hardware timestamping subsystem from Thierry Reding:
"This contains the new HTE (hardware timestamping engine) subsystem
that has been in the works for a couple of months now.
The infrastructure provided allows for drivers to register as hardware
timestamp providers, while consumers will be able to request events
that they are interested in (such as GPIOs and IRQs) to be timestamped
by the hardware providers.
Note that this currently supports only one provider, but there seems
to be enough interest in this functionality and we expect to see more
drivers added once this is merged"

platforms as another future timestamp provider ]

Pull ptrace_stop cleanups from Eric Biederman:
"While looking at the ptrace problems with PREEMPT_RT and the problems
Peter Zijlstra was encountering with ptrace in his freezer rewrite I
identified some cleanups to ptrace_stop that make sense on their own
and move make resolving the other problems much simpler.
The biggest issue is the habit of the ptrace code to change
task->__state from the tracer to suppress TASK_WAKEKILL from waking up
the tracee. No other code in the kernel does that and it is straight
forward to update signal_wake_up and friends to make that unnecessary.
Peter's task freezer sets frozen tasks to a new state TASK_FROZEN and
then it stores them by calling "wake_up_state(t, TASK_FROZEN)" relying
on the fact that all stopped states except the special stop states can
tolerate spurious wake up and recover their state.
The state of stopped and traced tasked is changed to be stored in
task->jobctl as well as in task->__state. This makes it possible for
the freezer to recover tasks in these special states, as well as
serving as a general cleanup. With a little more work in that
direction I believe TASK_STOPPED can learn to tolerate spurious wake
ups and become an ordinary stop state.
The TASK_TRACED state has to remain a special state as the registers
for a process are only reliably available when the process is stopped
in the scheduler. Fundamentally ptrace needs acess to the saved
register values of a task.
There are bunch of semi-random ptrace related cleanups that were found
while looking at these issues.
One cleanup that deserves to be called out is from commit 57b6de08b5f6
("ptrace: Admit ptrace_stop can generate spuriuos SIGTRAPs"). This
makes a change that is technically user space visible, in the handling
of what happens to a tracee when a tracer dies unexpectedly. According
to our testing and our understanding of userspace nothing cares that
spurious SIGTRAPs can be generated in that case"

Commit 23cfbc6ec44e ("firmware: Add the support for ZSTD-compressed
firmware files") added support for ZSTD compression, but in the process
also made the previously default XZ compression a config option.
That means that anybody who upgrades their kernel and does a
make oldconfig
to update their configuration, will end up without the XZ compression
that the configuration used to have.
Add the 'default y' to make sure this doesn't happen.
The whole compression question should probably be improved upon, since
it is now possible to "enable" compression in the kernel config but not
enable any actual compression algorithm, which makes it all very
useless. It makes no sense to ask Kconfig questions that enable
situations that are nonsensical like that.
This at least fixes the immediate problem of a kernel update resulting
in a nonbootable machine because of a missed option.
