ATU (Address Translation Unit) is a new IOMMU in SPARC supported with
Hypervisor IOMMU v2 APIs.
Current SPARC IOMMU supports only 32bit address ranges and one TSB
per PCIe root complex that has a 2GB per root complex DVMA space
limit. The limit has become a scalability bottleneck nowadays that
a typical 10G/40G NIC can consume 300MB-500MB DVMA space per
instance. When DVMA resource is exhausted, devices will not be usable
since the driver can't allocate DVMA.
ATU removes bottleneck by allowing guest os to create IOTSB of size
32G (or more) with 64bit address ranges available in ATU HW. 32G is
more than enough DVMA space to be shared by all PCIe devices under
root complex contrast to 2G space provided by legacy IOMMU.
ATU allows PCIe devices to use 64bit DMA addressing. Devices
which choose to use 32bit DMA mask will continue to work with the
existing legacy IOMMU.

This adds the cpus node to the Integrator/AP device tree so
that we have a proper placeholder to put in the DT-defined
operating points for the generic DT/OPP cpufreq driver,
along with the proper operating points.
The old Integrator cpufreq driver would resolve the max
frequency to 71MHz, and the min frequency to 12 MHz, but
the clock driver can actually handle any frequency inbetween
so I picked a few select frequencies as OPPs. The cpufreq
framework doesn't seem to deal with sliding frequency scales,
only fixed points so 7 OPPs is better than 2 atleast.
We define a CPU node since this is required for cpufreq-dt,
however we do not define any compatible string for the CPU
since this architecture has pluggable CPU modules and we
do not know which one will be used. If necessary, the CPU
compatible can be filled in by the boot loader, but for
just cpufreq-dt it is not required.

This adds the cpus node to the Integrator/CP device tree so
that we have a proper placeholder to put in the DT-defined
operating points for the generic DT/OPP cpufreq driver,
along with two working operating points.
I have only put in 48 and 50 MHz because going to e.g. 36
MHz hangs the system when CLCD graphics are active.
Presumably the memory bus gets to slow to feed the display
and the systems hangs for this reason. The ideal solution
would be for the display controller to put constraints on
the memory bus frequency, but that need to be a separate
longer-term project.

Signed-off-by: Pratyush Anand <panand@redhat.com>
Signed-off-by: Will Deacon <will.deacon@arm.com>
Arm64 hardware does not always report a watchpoint hit address that
matches one of the watchpoints set. It can also report an address
"near" the watchpoint if a single instruction access both watched and
unwatched addresses. There is no straight-forward way, short of
disassembling the offending instruction, to map that address back to
the watchpoint.
Previously, when the hardware reported a watchpoint hit on an address
that did not match our watchpoint (this happens in case of instructions
which access large chunks of memory such as "stp") the process would
enter a loop where we would be continually resuming it (because we did
not recognise that watchpoint hit) and it would keep hitting the
watchpoint again and again. The tracing process would never get
notified of the watchpoint hit.
This commit fixes the problem by looking at the watchpoints near the
address reported by the hardware. If the address does not exactly match
one of the watchpoints we have set, it attributes the hit to the
nearest watchpoint we have. This heuristic is a bit dodgy, but I don't
think we can do much more, given the hardware limitations.

ARM64 hardware supports watchpoint at any double word aligned address.
However, it can select any consecutive bytes from offset 0 to 7 from that
base address. For example, if base address is programmed as 0x420030 and
byte select is 0x1C, then access of 0x420032,0x420033 and 0x420034 will
generate a watchpoint exception.
Currently, we do not have such modularity. We can only program byte,
halfword, word and double word access exception from any base address.
This patch adds support to overcome above limitations.

usb: patches for v4.10 merge window
One big merge this time with a total of 166 non-merge commits.
Most of the work, by far, is on dwc2 this time (68.2%) with dwc3 a far
second (22.5%). The remaining 9.3% are scattered on gadget drivers.
The most important changes for dwc2 are the peripheral side DMA support
implemented by Synopsys folks and support for the new IOT dwc2
compatible core from Synopsys.
In dwc3 land we have support for high-bandwidth, high-speed isochronous
endpoints and some non-critical fixes for large scatter lists.
Apart from these, we have our usual set of cleanups, non-critical fixes,

The ibm_pa_features array consists of structures that describe which bit
and byte in the ibm,pa-features property toggles one or more flags in
either the CPU, MMU, or user visible feature flags.
Each one consists of 7 values, which are all unsigned long, int or char,
meaning the compiler gives us no warning if we assign the wrong values
to the wrong elements. In fact we have had a bug here in the past, where
we were setting incorrect bits, see commit 6997e57d69 ("powerpc:
scan_features() updates incorrect bits for REAL_LE").
So switch to using named initialisers for the structure elements, to
reduce the likelihood of future bugs, and hopefully improve readability
also.
