Add initial device tree support for the ASPEED AST27xx family, the
8th-generation Baseboard Management Controller (BMC) SoCs.
AST27xx SOC Family
- https://www.aspeedtech.com/server_ast2700/
- https://www.aspeedtech.com/server_ast2720/
- https://www.aspeedtech.com/server_ast2750/
The AST27xx features a dual-SoC architecture consisting of two dies,
referred to as SoC0 and SoC1 - interconnected through an internal
proprietary bus. Both SoCs share the same address decoding scheme,
while each maintains independent clock and reset domains.
- SoC0 (CPU die): contains a quad-core Cortex-A35 cluster and two
Cortex-M4 cores, along with high-speed peripherals.
- SoC1 (I/O die): includes the BootMCU (responsible for system
boot) and its own clock/reset domains low-speed peripherals.
The device tree describes the SoC0 and SoC1 domains and their peripheral
layouts.

This configuration option exists so "that we don't provide the symbol
when there's no possibility of there being a usable clocksource".
However it only covers __vdso_gettimeofday() and none of the other vDSO

The text display code used in the Risc PC kernel image decompression
code uses arch/arm/boot/compressed/font.c, which includes
lib/fonts/font_acorn_8x8.c, which further includes <linux/font.h>.
Since commit 97df8960240a ("lib/fonts: Provide helpers for calculating
glyph pitch and size") <linux/font.h> contains inline functions that
require __do_div64, which is not linked into the ARM kernel
decompressor. This makes Risc PC zImages fail to build.
Resolve this issue by defining the BOOTLOADER symbol and use it to avoid
a static declaration of the acorndata_8x8 symbol. That way it can be
referenced by the arm bootloader, and other static math functions and
symbols (like __do_div64) stay static and don't get unneccesary included
in the ARM kernel bootloader decompressor object file.
Fixes: 97df8960240a ("lib/fonts: Provide helpers for calculating glyph pitch and size")

MIPI CSI-2 is supported on the A83T with a dedicated controller that
covers both the protocol and D-PHY. It is connected to the only CSI
receiver with a fwnode graph link. Note that the CSI receiver supports
both this MIPI CSI-2 source and a parallel source.
An empty port with a label for the MIPI CSI-2 sensor input is also
defined for convenience.

aspeed: First batch of ARM devicetree changes for v7.2
New platforms:
- Rainiera6 (Meta)
- SanMiguel (Meta)
Updated platforms:
- Anacapa: SGPIO line names and interrupt configuration
- Clemente: Remove TMP421 nodes
- Kommando: Enable networking via MAC2/MDIO2
- SanMiguel: Line names and interrupt configuration
AST2600 SoC updates:
- Describe PWM/Tach
- Describe I3C controllers
- Reorganise I2C nodes
Other notes:
91b9aed7381c ("ARM: dts: aspeed-g6: Add nodes for i3c controllers") currently
causes a new warning:
... /ahb/apb/bus@1e7a0000/syscon@0: failed to match any schema with compatible: ['aspeed,ast2600-i3c-global', 'syscon']
The patch necessary to address it has an R-b tag from Kryzsztof[2] but as best
I can tell is yet to be applied to the MFD tree. I've left the change in for now
as the warning will resolve once the binding patch is applied.
Lastly, as part of improving support for the Kommando card Anirudh has also
addressed[1] the persistent pain we've had with the phy-mode property for the
AST2600 MACs. Thanks to Andrew Lunn for being on the case for a while now, and
for those who tested Anirudh's patch.

RISC-V Devicetrees for v7.2
Sophgo:
For CV18xx serials:
- Add bindings for Milk-V "Duo S" board.
For SG2042:
- The CPU unit address incorrectly used decimal numbers,
especially for those nodes which value >= 10. Now
corrected to use hexadecimal.
- The MSI controller actually only supports 16 interrupts;
corrected to match the actual situation.
- PCIe RCs are cache-coherent with the CPU. Marked it out
for RC nodes.
For SG2044:
- The same as SG2042, use hex for CPU unit address.
In additional, update Chen Wang's email address for Sopgho

Tenstorrent device tree for v7.2
Add a riscv,pmu node to the Tenstorrent Blackhole SoC device tree. This
enables OpenSBI to expose the SBI PMU extension, allowing Linux perf to
use the 4 programmable counters (mhpmcounter3-6) across 3 event classes:
instruction commit, microarchitectural, and memory system events.
Extend the RISC-V IOMMU device tree bindings to document the Tenstorrent
IOMMU used in the Tenstorrent Atlantis SoC. A second register range is
added which contains M-mode only registers like PMAs and PMPs. The
binding will be used by OpenSBI and potentially other M-mode software.

the relevant supported boards in place of MT6359, where
needed (the MT6365 PMIC is a fully compatible variant
of the MT6359 PMIC, but still not named MT6359).

writes
Recursively zap orphaned nested TDP shadow pages when emulating a guest
write to a shadowed page table, regardless of whether or not the associated
(parent) shadow page will be zapped, e.g. due to detected write-flooding.
This plugs a hole where KVM fails to reclaim defunct, unsync shadow pages
for select L1 hypervisor patterns. Commit 2de4085cccea ("KVM: x86/MMU:
Recursively zap nested TDP SPs when zapping last/only parent") modified KVM
to recursively zap synchronized shadow pages (KVM already recursively zaps
unsync children) when a child is orphaned. But the fix effectively only
applied the logic to kvm_mmu_page_unlink_children(), i.e. only performs the
recursive zap when KVM is already zapping a parent SP and processing its
children.
If L1 zaps SPTEs bottom-up (4KiB => 2MiB => ...), as KVM's TDP MMU does
with CONFIG_KVM_PROVE_MMU=n since commit 8ca983631f3c ("KVM: x86/mmu: Zap
invalidated TDP MMU roots at 4KiB granularity"), then KVM (as L0) will leak
upwards of 4 shadow pages per GiB of L2 guest memory. Over hundreds or
thousands of L2 boots, if the VM is "lucky" enough to escape write-flooding
detection, i.e. not trigger reclaim of the orphaned shadow pages by dumb
luck, then it's possible to end up with tens or even hundreds of thousands
of unsync shadow pages and associated rmap entries.
Polluting the hash table and rmap entries with a horde of stale entries
can eventually degrade L2 guest boot time by an order of magnitude,
especially if there is any antagonistic activity in the host, i.e. anything
that will contend for mmu_lock and/or needs to walk rmaps.
With "top"-down zapping, where "top" is 1GiB or above, then L0 KVM is
effectively limited to leaking 4 shadow pages per 256 GiB of memory, as
KVM's write flooding detection will kick in on the third write to an L1
TDP PUD, and thus recursively zap the entire 256 GiB range of the parent
PGD. I.e. even though L1 KVM still recursively zaps 2MiB => 4KiB SPTEs
when zapping each 1GiB SPTE, KVM only gets through two of the 1GiB SPTEs
before dropping everything. E.g. hacking tracing into L0 KVM's
kvm_mmu_track_write(), the top-down zapping of L1's TDP MMU for an L2 with
16GiB of memory leads to:

Contrast that with a bottom-up zap, which effectively allows all 2MiB SPTEs
in L1 to leak their children.

Note, in the shadow MMU, "level" describes the level a shadow page "points"
at, not the level of its associated SPTE. I.e. when write-flooding of 1GiB
PUD entries is detected, KVM recursively zaps shadow pages covering 256GiB
worth of memory. And as shown above, KVM's write-flooding detection
operates at all levels, so a single PMD (in L1) can effectively only leak
two unsync children (4KiB shadow pages) before it gets recursively zapped.
As a result, for the top-down zap, L0 KVM will leak at most 4 unsync shadow
pages per 256GiB of L2 memory.
The top-down zap also makes it more likely that L1 will self-heal (to some
extent), as any shadow pages that are "rediscovered" by future runs of L2
can get reclaimed by a recursive zap, whereas bottom-up zapping orphans
shadow pages over and over.
Note, in theory, there is some risk of over-zapping, e.g. due to zapping a
a large branch of the paging tree that L1 is only temporarily removing. In
practice, the usage patterns of hypervisors are highly unlikely to trigger
false positives. E.g. temporarily changing paging protections is typically
done at the leaf, not on a non-leaf entry. And if the L1 hypervisor is
updating large swaths of PTEs, e.g. to (temporarily?) remove chunks of
memory from L2, then L0 KVM's write-flooding detection will kick in, and
the children would be zapped anyways.
