41ebfc91f7 dt-bindings: riscv: explicitly mention assumption of Zicsr & Zifencei support
The dt-binding was defined before the extraction of csr access and
fence.i into their own extensions, and thus the presence of the I
base extension implies Zicsr and Zifencei.
There's no harm in adding them obviously, but for backwards
compatibility with DTs that existed prior to that extraction, software
is unable to differentiate between "i" and "i_zicsr_zifencei" without
any further information.

dc8ea9204b dt-bindings: move cache controller bindings to a cache directory
There's a bunch of bindings for (mostly l2) cache controllers
scattered to the four winds, move them to a common directory.
I renamed the freescale l2cache.txt file, as while that might make sense
when the parent dir is fsl, it's confusing after the move.
The two Marvell bindings have had a "marvell," prefix added to match
their compatibles.

ea20f117ab dt-bindings: riscv: Document cboz-block-size
The Zicboz operation (cbo.zero) operates on a block-size defined
for the cpu-core. While we already have the riscv,cbom-block-size
property, it only provides the block size for Zicbom operations.
Even though it's likely Zicboz and Zicbom will use the same size,
that's not required by the specification. Create another property
specifically for Zicboz.

Pull SoC DT updates from Arnd Bergmann:
 "About a quarter of the changes are for 32-bit arm, mostly filling in
  device support for existing machines and adding minor cleanups, mostly
  for Qualcomm and Samsung based machines.

  Two new 32-bit SoCs are added, both are quad-core Cortex-A7 chips from
  Rockchips that have been around for a while but were lacking kernel
  support so far: RV1126 is a Vision SoC with an NPU and is used in the
  Edgeble Neural Compute Module 2(Neu2) board, while RK3128 is design
  for TV boxes and so far only comes with a dts for its refernece
  design.

  The other 32-bit boards that were added are two ASpeed AST2600 based
  BMC boards, the Microchip sam9x60_curiosity development board (Armv5
  based!), the Enclustra PE1 FPGA-SoM baseboard, and a few more boards
  for i.MX53 and i.MX6ULL.

  On the RISC-V side, there are fewer patches, but a total of ten new
  single-board computers based on variations of the Allwinner D1/T113
  chip, plus one more board based on Microchip Polarfire.

  As usual, arm64 has by far the most changes here, with over 700
  non-merge changesets, among them over 400 alone for Qualcomm. The
  newly added SoCs this time are all recent high-end embedded SoCs for
  various markets, each on comes with support for its reference board:

   - Qualcomm SM8550 (Snapdragon 8 Gen 2) for mobile phones
   - Qualcomm QDU1000/QRU1000 5G RAN platform
   - Rockchips RK3588/RK3588s for tablets, chromebooks and SBCs
   - TI J784S4 for industrial and automotive applications

  In total, there are 46 new arm64 machines:
   - Reference platforms for each of the five new SoCs
   - Three Amlogic based development boards
   - Six embedded machines based on NXP i.MX8MM and i.MX8MP
   - The Mediatek mt7986a based Banana Pi R3 router
   - Six tablets based on Qualcomm MSM8916 (Snapdragon 410), SM6115
     (Snapdragon 662) and SM8250 (Snapdragon 865)
   - Two LTE dongles, also based on MSM8916
   - Seven mobile phones, based on Qualcomm MSM8953 (Snapdragon 610),
     SDM450 and SDM632
   - Three chromebooks based on Qualcomm SC7280 (Snapdragon 7c)
   - Nine development boards based on Rockchips RK3588, RK3568, RK3566
     and RK3328.
   - Five development machines based on TI K3 (AM642/AM654/AM68/AM69)

  The cleanup of dtc warnings continues across all platforms, adding to
  the total number of changes"

e43efb6d71 dt-bindings: riscv: correct starfive visionfive 2 compatibles
Using "va" and "vb" doesn't match what's written on the board, or the
communications from StarFive.
Switching to using the silkscreened version number will ease confusion &
the risk of another spin of the board containing a "conflicting" version
identifier.
As the binding has not made it into mainline yet, take the opportunity
to "correct" things.

information from the DT though, so document the one already used by the
generic arch topology code: "capacity-dmips-mhz".

From: Conor Dooley <conor.dooley@microchip.com>

I noticed ~today~ while looking at the isa manual that I had not
accounted for another couple of edge cases with my regex. As before, I
think attempting to validate the canonical order for multiletter stuff
makes no sense - but we should totally try to avoid false-positives for
combinations that are known to be valid.

I used the wikipedia table for ordering extensions when updating the
pattern here in commit 299824e68b ("dt-bindings: riscv: add new
riscv,isa strings for emulators").

Unfortunately that table did not match canonical order, as defined by
the RISC-V ISA Manual, which defines extension ordering in (what is
currently) Table 41, "Standard ISA extension names". Fix things up by
re-sorting v (vector) and adding p (packed-simd) & j (dynamic
languages). The e (reduced integer) and g (general) extensions are still
intentionally left out.

ec64efc496 dt-bindings: riscv: fix underscore requirement for multi-letter extensions
The RISC-V ISA Manual allows the first multi-letter extension to avoid
a leading underscore. Underscores are only required between multi-letter
extensions.

The dt-binding does not validate that a multi-letter extension is
canonically ordered, as that'd need an even worse regex than is here,
but it should not fail validation for valid ISA strings.

Allow the first multi-letter extension to appear immediately after
the single-letter extensions.

Conor Dooley <mail@conchuod.ie> says:

From: Conor Dooley <conor.dooley@microchip.com>

The device trees produced automatically for the virt and spike machines
fail dt-validate on several grounds. Some of these need to be fixed in
the linux kernel's dt-bindings, but others are caused by bugs in QEMU.

Patches been sent that fix the QEMU issues [0], but a couple of them
need to be fixed in the kernel's dt-bindings. The first patches add
compatibles for "riscv,{clint,plic}0" which are present in drivers and
the auto generated QEMU dtbs.

Thanks to Rob Herring for reporting these issues [1],
Conor.

To reproduce the errors:

dt-validate -p /path/to/linux/kernel/Documentation/devicetree/bindings/processed-schema.json qemu.dtb

299824e68b dt-bindings: riscv: add new riscv,isa strings for emulators
The QEMU virt and spike machines currently export a riscv,isa string of
"rv64imafdcsuh",

While the RISC-V foundation has been ratifying a bunch of extenstions
etc, the kernel has remained relatively static with what hardware is
supported - but the same is not true of QEMU. Using the virt machine
and running dt-validate on the dumped dtb fails, partly due to the
unexpected isa string.

Rather than enumerate the many many possbilities, change the pattern
to a regex, with the following assumptions:
- ima are required
- the single letter order is fixed & we don't care about things that
  can't even do "ima"
- the standard multi letter extensions are all in a "_z<foo>" format
  where the first letter of <foo> is a valid single letter extension
- _s & _h are used for supervisor and hyper visor extensions
- convention says that after the first two chars, a standard multi
  letter extension name could be an english word (ifencei anyone?) so
  it's not worth restricting the charset
- as the above is just convention, don't apply any charset restrictions
  to reduce future churn
- vendor ISA extensions begind with _x and have no charset restrictions
- we don't care about an e extension from an OS pov
- that attempting to validate the contents of the multiletter extensions
  with dt-validate beyond the formatting is a futile, massively verbose
  or unwieldy exercise at best

The following limitations also apply:
- multi letter extension ordering is not enforced. dt-schema does not
  appear to allow for named match groups, so the resulting regex would
  be even more of a headache
- ditto for the numbered extensions

Finally, add me as a maintainer of the binding so that when it breaks
in the future, I can be held responsible!

a0d49a8f77 dt-bindings: riscv: microchip: document icicle reference design
The icicle kit reference design's v2022.09 release made some changes
to the memory map - including adding the ability to read the fabric
clock controllers via the system controller bus & making the PCI
controller work with upstream Linux.

While the PCI was not working in the v2022.03 design, so nothing is
broken there in terms of backwards compatibility, the fabric clocks
used in the v2022.03 design were chosen by the individual run of the
synthesis tool. In the v2022.09 reference design, the clocks are fixed
to use the "north west" fabric Clock Conditioning Circuitry.

In the v2022.10 release, the memory map on the DDR side is also
changing, so to avoid making a breaking change here twice, jump over the
v2022.09 release and straight to the v2022.10 one.

Make use of a new compatible to denote that v2022.{09,10} reference
design releases are not backwards compatible.

b60cf8e59e dt-bindings: riscv: fix SiFive l2-cache's cache-sets
Fix device tree schema validation error messages for the SiFive
Unmatched: ' cache-sets:0:0: 1024 was expected'.

The existing bindings allow for just 1024 cache-sets but the fu740 on
Unmatched the has 2048 cache-sets. The ISA itself permits any arbitrary
power of two, however this is not supported by dt-schema. The RTL for
the IP, to which the number of cache-sets is a tunable parameter, has
been released publicly so speculatively adding a small number of
"reasonable" values seems unwise also.

Instead, as the binding only supports two distinct controllers: add 2048
and explicitly lock it to the fu740's l2 cache while limiting 1024 to
the l2 cache on the fu540.
