9a34e7ad2e dt-bindings: interconnect: Document the support of optional path tag
Let's document that we now support specifying path tag information in the
arg cells of the 'interconnects' DT property. This information would be
populated when the xlate_extended() callback is used.

Specifying the tag in DT will allow the interconnect framework to do the
aggregation based on the tag automatically. The users can still use the
icc_set_tag() API if/when needed.

1521e22bfa interconnect: Introduce xlate_extended() callback
Currently there is the xlate() callback, which is used by providers for
mapping the nodes from phandle arguments. That's fine for simple mappings,
but the phandle arguments could contain an additional data, such as tag
information. Let's create another callback xlate_extended() for the cases
where providers want also populate the path tag data.

cb30e0292d interconnect: qcom: Add support for per-BCM scaling factors
Currently, bcm-voter always assumes requests are made in KBps and that
BCM HW always wants them in Bps, so it always scales the requests by
1000. However, certain use cases and BCMs may use different units.
Thus, add support for BCM-specific scaling factors.

db474be2b6 interconnect: qcom: Only wait for completion in AMC/WAKE by default
Change the default TCS wait behavior to only wait for completion in AMC
and WAKE. Waiting isn't necessary in the SLEEP TCS, since votes are only
being removed in this case. Resources can be safely disabled
asynchronously in parallel with the rest of the power collapse sequence.
This reduces the sleep entry latency.

b92902fddf interconnect: qcom: Support bcm-voter-specific TCS wait behavior
Currently, all bcm-voters set tcs_cmd::wait=true for the last VCD
command in each TCS (AMC, WAKE, and SLEEP). However, some bcm-voters
don't need the completion and instead need to optimize for latency. For
instance, disabling wait-for-completion in the WAKE set can decrease
resume latency and allow for certain operations to occur in parallel
with the WAKE TCS triggering. This is only safe in very specific
situations. Keep the default behavior of always waiting, but allow it to
be overridden in devicetree.

b41b0ce598 interconnect: Add bulk API helpers
There are drivers which just need to get multiple interconnect paths,
request some predefined amounts of bandwidth and then just toggle the
paths between enabled/disabled state.

The aim of this patch is simplify the above and to allow drivers to put
all the path names and bandwidth data into a single static icc_bulk_data
table and call the icc_bulk_* functions on that table in order to scale
all the interconnect paths in parallel.

dcc5c6f013 Merge tag 'x86-urgent-2020-08-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner:
 "Three interrupt related fixes for X86:

   - Move disabling of the local APIC after invoking fixup_irqs() to
     ensure that interrupts which are incoming are noted in the IRR and
     not ignored.

   - Unbreak affinity setting.

     The rework of the entry code reused the regular exception entry
     code for device interrupts. The vector number is pushed into the
     errorcode slot on the stack which is then lifted into an argument
     and set to -1 because that's regs->orig_ax which is used in quite
     some places to check whether the entry came from a syscall.

     But it was overlooked that orig_ax is used in the affinity cleanup
     code to validate whether the interrupt has arrived on the new
     target. It turned out that this vector check is pointless because
     interrupts are never moved from one vector to another on the same
     CPU. That check is a historical leftover from the time where x86
     supported multi-CPU affinities, but not longer needed with the now
     strict single CPU affinity. Famous last words ...

   - Add a missing check for an empty cpumask into the matrix allocator.

     The affinity change added a warning to catch the case where an
     interrupt is moved on the same CPU to a different vector. This
     triggers because a condition with an empty cpumask returns an
     assignment from the allocator as the allocator uses for_each_cpu()
     without checking the cpumask for being empty. The historical
     inconsistent for_each_cpu() behaviour of ignoring the cpumask and
     unconditionally claiming that CPU0 is in the mask struck again.
     Sigh.

784a083037 genirq/matrix: Deal with the sillyness of for_each_cpu() on UP
Most of the CPU mask operations behave the same way, but for_each_cpu() and
it's variants ignore the cpumask argument and claim that CPU0 is always in
the mask. This is historical, inconsistent and annoying behaviour.

The matrix allocator uses for_each_cpu() and can be called on UP with an
empty cpumask. The calling code does not expect that this succeeds but
until commit e027fffff7 ("x86/irq: Unbreak interrupt affinity setting")
this went unnoticed. That commit added a WARN_ON() to catch cases which
move an interrupt from one vector to another on the same CPU. The warning
triggers on UP.

Add a check for the cpumask being empty to prevent this.

0a4c56c80f fsldma: fix very broken 32-bit ppc ioread64 functionality
Commit ef91bb196b ("kernel.h: Silence sparse warning in
lower_32_bits") caused new warnings to show in the fsldma driver, but
that commit was not to blame: it only exposed some very incorrect code
that tried to take the low 32 bits of an address.

That made no sense for multiple reasons, the most notable one being that
that code was intentionally limited to only 32-bit ppc builds, so "only
low 32 bits of an address" was completely nonsensical.  There were no
high bits to mask off to begin with.

But even more importantly fropm a correctness standpoint, turning the
address into an integer then caused the subsequent address arithmetic to
be completely wrong too, and the "+1" actually incremented the address
by one, rather than by four.

Which again was incorrect, since the code was reading two 32-bit values
and trying to make a 64-bit end result of it all.  Surprisingly, the
iowrite64() did not suffer from the same odd and incorrect model.

This code has never worked, but it's questionable whether anybody cared:
of the two users that actually read the 64-bit value (by way of some C
preprocessor hackery and eventually the 'get_cdar()' inline function),
one of them explicitly ignored the value, and the other one might just
happen to work despite the incorrect value being read.

This patch at least makes it not fail the build any more, and makes the
logic superficially sane.  Whether it makes any difference to the code
_working_ or not shall remain a mystery.
