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.

In musb_remove() cancel_delayed_work_sync(&musb->irq_work)
is called which flush the irq_work work queue.
After cancel delayed work, musb_remove() call
musb_gadget_cleanup->usb_del_gadget_udc->usb_del_gadget
->usb_gadget_remove_driver->usb_gadget_udc_stop->udc
->gadget->ops->udc_stop(udc->gadget);
Where musb_gadget_stop() call "schedule_delayed_work(&musb->irq_work, 0)”
which is already cancel/flush.
So remove the schedule_delayed_work(&musb->irq_work, 0);
from musb_gadget_stop function.

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.

The bluetooth code uses our bitmap infrastructure for the two bits (!)
of connection setup flags, and in the process causes odd problems when
it converts between a bitmap and just the regular values of said bits.
It's completely pointless to do things like bitmap_to_arr32() to convert
a bitmap into a u32. It shoudln't have been a bitmap in the first
place. The reason to use bitmaps is if you have arbitrary number of
bits you want to manage (not two!), or if you rely on the atomicity
guarantees of the bitmap setting and clearing.
The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
clear the bit values, but considering that it then copies the bitmaps
around with "bitmap_to_arr32()" and friends, there clearly cannot be a
lot of atomicity requirements.
So just use a regular integer.
In the process, this avoids the warnings about erroneous use of
bitmap_from_u64() which were triggered on 32-bit architectures when
conversion from a u64 would access two words (and, surprise, surprise,
only one word is needed - and indeed overkill - for a 2-bit bitmap).
That was always problematic, but the compiler seems to notice it and
warn about the invalid pattern only after commit 0a97953fd221 ("lib: add
bitmap_{from,to}_arr64") changed the exact implementation details of
'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

lottery and broken.

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 ]
