Every SPI transfer could have a different clock rate.  The
spi-geni-qcom controller code to deal with this was never very well
optimized and has always had a lot of code plus some calls into the
clk framework which, at the very least, would grab a mutex.  However,
until recently, the overhead wasn't _too_ much.  That changed with
commit 0e3b8a81 ("spi: spi-geni-qcom: Add interconnect support")
we're now calling geni_icc_set_bw(), which leads to a bunch of math
plus:
  geni_icc_set_bw()
    icc_set_bw()
      apply_constraints()
        qcom_icc_set()
          qcom_icc_bcm_voter_commit()
            rpmh_invalidate()
            rpmh_write_batch()
...and those rpmh commands can be a bit beefy if you call them too
often.

We already know what speed we were running at before, so if we see
that nothing has changed let's avoid the whole pile of code.

On my hardware, this made spi_geni_prepare_message() drop down from
~145 us down to ~14 us.

NOTE: Potentially it might also make sense to add some code into the
interconnect framework to avoid executing so much code when bandwidth
isn't changing, but even if we did that we still want to short circuit
here to save the extra math / clock calls.

In commit cff80645 ("spi: spi-qcom-qspi: Add interconnect support")
the spi_geni_runtime_suspend() and spi_geni_runtime_resume()
became a bit slower.  Measuring on my hardware I see numbers in the
hundreds of microseconds now.

Let's use autosuspend to help avoid some of the overhead.  Now if
we're doing a bunch of transfers we won't need to be constantly
chruning.

The number 250 ms for the autosuspend delay was picked a bit
arbitrarily, so if someone has measurements showing a better value we
could easily change this.

As per recent changes to the spi-qcom-qspi, now when we set the clock
we'll call into the interconnect framework and also call the OPP API.
Those are expensive operations.  Let's avoid calling them if possible.
This has a big impact on getting transfer rates back up to where they
were (or maybe slightly better) before those patches landed.

with a -95 return code). Switch back to using the atomic calls.

The write_tcs_reg_sync() may be called after timekeeping is suspended
so it's not OK to use ktime.  The readl_poll_timeout_atomic() macro
implicitly uses ktime.  This was causing a warning at suspend time.

Change to just loop 1000000 times with a delay of 1 us between loops.
This may give a timeout of more than 1 second but never less and is
safe even if timekeeping is suspended.

NOTE: I don't have any actual evidence that we need to loop here.
It's possibly that all we really need to do is just read the value
back to ensure that the pipes are cleaned and the looping/comparing is
totally not needed.  I never saw the loop being needed in my tests.
However, the loop shouldn't hurt.

This reverts commit a43a67a2.

This patch reverts the main part of switching direct io implementation
to iomap infrastructure. There's a problem in invalidate page that
couldn't be solved as regression in this development cycle.

The problem occurs when buffered and direct io are mixed, and the ranges
overlap. Although this is not recommended, filesystems implement
measures or fallbacks to make it somehow work. In this case, fallback to
buffered IO would be an option for btrfs (this already happens when
direct io is done on compressed data), but the change would be needed in
the iomap code, bringing new semantics to other filesystems.

Another problem arises when again the buffered and direct ios are mixed,
invalidation fails, then -EIO is set on the mapping and fsync will fail,
though there's no real error.

There have been discussions how to fix that, but revert seems to be the
least intrusive option.

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow

This happens, because ALE VLAN entries on these SoCs do not contain port
masks for reg/unreg mcast packets, but instead store indexes of
ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
reg/unreg mcast packets.
