Some of the RCGs could be always ON from the XO source and could be used
as the clock on signal for the GDSC to be operational. In the cases where
the GDSCs are parked at different source with the source clock disabled,
it could lead to the GDSC to be stuck at ON/OFF during gdsc disable/enable.
Thus park the RCGs at XO during clock disable and update the rcg_ops to
use the shared_ops.

While picking commit a8cd989e ("mmc: sdhci-msm: Warn about
overclocking SD/MMC") back to my tree I was surprised that it was
reporting warnings.  I thought I fixed those!  Looking closer at the
fix, I see that I totally bungled it (or at least I halfway bungled
it).  The SD card clock got fixed (and that was the one I was really
focused on fixing), but I totally adjusted the wrong clock for eMMC.
Sigh.  Let's fix my dumb mistake.

Now both SD and eMMC have floor for the "apps" clock.

This doesn't matter a lot for the final clock rate for HS400 eMMC but
could matter if someone happens to put some slower eMMC on a sc7180.
We also transition through some of these lower rates sometimes and
having them wrong could cause problems during these transitions.
These were the messages I was seeing at boot:
  mmc1: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz
  mmc1: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz

In case the mux is not divided parent_req was mistakenly not assigned to
leading __clk_determine_rate to determine the best frequency setting for
a requested rate of 0, resulting in the msm8996 platform not booting.
Rectify this by refactoring the logic to unconditionally assign to
parent_req.rate with the clock rate the caller is expecting.

Pull io_uring fixes from Jens Axboe:
 "A bit of a mix between fallout from the worker change, cleanups and

   - 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
