Detecting the ATS capability of the SMMU at probe time introduces a
spinlock into the ->unmap() fast path, even when ATS is not actually
in use. Furthermore, the ATC invalidation that exists is broken, as it
occurs before invalidation of the main SMMU TLB which leaves a window
where the ATC can be repopulated with stale entries.
Given that ATS is both a new feature and a specialist sport, disable it
for now whilst we fix it properly in subsequent patches. Since PRI
requires ATS, disable that too.

After _gadget_stop_activity is executed, we can consider the hardware
operation for gadget has finished, and the udc can be stopped and enter
low power mode. So, any later hardware operations (from usb_ep_ops APIs
or usb_gadget_ops APIs) should be considered invalid, any deinitializatons
has been covered at _gadget_stop_activity.
I meet this problem when I plug out usb cable from PC using mass_storage
gadget, my callstack like: vbus interrupt->.vbus_session->
composite_disconnect ->pm_runtime_put_sync(&_gadget->dev),
the composite_disconnect will call fsg_disable, but fsg_disable calls
usb_ep_disable using async way, there are register accesses for
usb_ep_disable. So sometimes, I get system hang due to visit register
without clock, sometimes not.
The Linux Kernel USB maintainer Alan Stern suggests this kinds of solution.

We're not allowed to create new properties after device registration
so for MST connectors we need to either create the max_bpc property

Current code erroneously sets-up the CPU base address through the
parameter 'pci_addr', which is passed to initialize the CPU (AXI) base
address of the inbound window where the controller maps the PCI address
space into CPU physical address space; furthermore, it also truncates it
by programming only the lower 32-bit value into the inbound CPU address
register.
Fix both issues by introducing a new parameter 'u64 cpu_addr' to
initialize both lower 32-bit and upper 32-bit of the CPU physical
base address mapping PCI inbound transactions into CPU (AXI) ones.

ODP is working with userspace VA's in the interval tree which always fit
into an unsigned long, so we can use the common code.
This comes at a cost of a 16 byte increase in ib_umem_odp struct size due
to storing the interval tree start/last in addition to the umem
addr/length. However these values were computed and are performance
critical for the interval lookup, so this seems like a worthwhile trade
off.

migration_base is used as a placeholder when an hrtimer is migrated to a
different CPU. In the case that hrtimer_cancel_wait_running() hits a timer
which is currently migrated it would pointlessly acquire the expiry lock of
the migration base, which is even not initialized.
Surely it could be initialized, but there is absolutely no point in
acquiring this lock because the timer is guaranteed not to run it's
callback for which the caller waits to finish on that base. So it would
just do the inc/lock/dec/unlock dance for nothing.
As the base switch is short and non-preemptible, there is no issue when the
wait function returns immediately.
The timer base and base->cpu_base cannot be NULL in the code path which is
invoking that, so just replace those checks with a check whether base is
migration base.

The update to timer->base is protected by the base->cpu_base->lock().
However, hrtimer_cancel_wait_running() does access it lockless. So the
compiler is allowed to refetch timer->base which can cause havoc when the
