MX8 SoC is comprised of a few HW subsystems while some of them can be
reused in the different SoCs. So let's re-orginize them into subsystems
in device tree as well for the possible reuse of the common part.
Note, as there's still no devices of hsio subsys, so removed it
first instead of creating a subsys headfile with no devices.
They will be added back when new devices added.

Pull io_uring fixes from Jens Axboe:
"A bit of a mix between fallout from the worker change, cleanups and
reductions now possible from that change, and fixes in general. In
detail:
- Fully serialize manager and worker creation, fixing races due to
that.
- Clean up some naming that had gone stale.
- SQPOLL fixes.
- Fix race condition around task_work rework that went into this
merge window.
- Implement unshare. Used for when the original task does unshare(2)
or setuid/seteuid and friends, drops the original workers and forks
new ones.
- Drop the only remaining piece of state shuffling we had left, which
was cred. Move it into issue instead, and we can drop all of that
code too.
- Kill f_op->flush() usage. That was such a nasty hack that we had
out of necessity, we no longer need it.
- Following from ->flush() removal, we can also drop various bits of
ctx state related to SQPOLL and cancelations.
- Fix an issue with IOPOLL retry, which originally was fallout from a
filemap change (removing iov_iter_revert()), but uncovered an issue
with iovec re-import too late.
- Fix an issue with system suspend.
- Use xchg() for fallback work, instead of cmpxchg().
- Properly destroy io-wq on exec.
- Add create_io_thread() core helper, and use that in io-wq and
io_uring. This allows us to remove various silly completion events
related to thread setup.
- A few error handling fixes.
This should be the grunt of fixes necessary for the new workers, next
week should be quieter. We've got a pending series from Pavel on
cancelations, and how tasks and rings are indexed. Outside of that,
should just be minor fixes. Even with these fixes, we're still killing
a net ~80 lines"

Pull power management fixes from Rafael Wysocki:
"These fix the usage of device links in the runtime PM core code and
update the DTPM (Dynamic Thermal Power Management) feature added
recently.
Specifics:
- Make the runtime PM core code avoid attempting to suspend supplier
devices before updating the PM-runtime status of a consumer to
'suspended' (Rafael Wysocki).
- Fix DTPM (Dynamic Thermal Power Management) root node
initialization and label that feature as EXPERIMENTAL in Kconfig
(Daniel Lezcano)"
* tag 'pm-5.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
powercap/drivers/dtpm: Add the experimental label to the option description
powercap/drivers/dtpm: Fix root node initialization
PM: runtime: Update device status before letting suppliers suspend
Make the empty stubs of some helper functions used when CONFIG_ACPI
is not set actually match those functions (Andy Shevchenko).

- Fix big endian conversion for arm64 in recordmcount processing
- Fix timestamp corruption in ring buffer on discarding events
- Fix memory leak in __create_synth_event()
- Skip selftests if tracing is disabled as it will cause them to fail.
Non-functional fixes:
- Fix help text in Kconfig
- Remove duplicate prototype for trace_empty()
- Fix stale comment about the trace_event_call flags.
Self test update:
- Add more information to the validation output of when a
corrupt timestamp is found in the ring buffer, and also
trigger a warning to make sure that tests catch it.

In rxe_comp.c in rxe_completer() the function free_pkt() did not clear skb
which triggered a warning at 'done:' and could possibly at 'exit:'. The
WARN_ONCE() calls are not actually needed. The call to free_pkt() is
moved to the end to clearly show that all skbs are freed.
