Subject: [PATCH v4 00/10] Add Milk-V Pioneer RISC-V board support

From: Chen Wang <[email protected]>

Milk-V Pioneer [1] is a developer motherboard based on SOPHON SG2042 [2]
in a standard mATX form factor. Add minimal device
tree files for the SG2042 SOC and the Milk-V Pioneer board.

Now only support basic uart drivers to boot up into a basic console.

Thanks,
Chen

Changes in v4:
The patch series is based on v6.6-rc1. You can simply review or test
the patches at the link [6].
- Update bindings files for sg2042 clint as per intput from reviewers:
- rename filename from sophgo,sg2042-clint-mswi/sg2042-clint-mtimer
to thead,c900-aclint-mswi/thead,c900-aclint-mtimer.
- rename compatible strings accordingly.
- Update dts as per input from reviewers: don't use macro for cpus's isa
properties; use new compatible strings for mtimer/mswi of clint.
- Use only one email-address for SoB.

Changes in v3 [v3]:
The patch series is based on v6.6-rc1. You can simply review or test
the patches at the link [5].
- add new vendor specific compatible strings to identify timer/mswi for sg2042 clint
- updated maintainers info. for sophgo devicetree
- remove the quirk changes for uart
- updated dts, such as:
- add "riscv,isa-base"/"riscv,isa-extensions" for cpus
- update l2 cache node's name
- remove memory and pmu nodes
- fixed other issues as per input from reviewers.

Changes in v2 [v2]:
The patch series is based on v6.6-rc1. You can simply review or test
the patches at the link [4].
- Improve format for comment of commitments as per input from last review.
- Improve format of DTS as per input from last review.
- Remove numa related stuff from DTS. This part is just for optimization, may
add it later if really needed.

Changes in v1:
The patch series is based on v6.6-rc1. Due to it is not sent in thread,
I have listed permlinks of the patchset [v1-0/12] ~ [v1-12/12] here for
quick reference. You can simply review or test the patches at the link [3].

Subject: [PATCH v4 06/10] dt-bindings: timer: Add Sophgo sg2042 CLINT timer

From: Inochi Amaoto <[email protected]>

The clint of Sophgo's sg2042 is based off IP designed by T-HEAD, but
Sophgo changes this IP layout to fit its cpu design and is incompatible
with the standard sifive clint. The timer and ipi device are on the
different address, and can not be handled by the sifive,clint dt-bindings.

If we use the same compatible string for mswi and timer of the sg2042
clint like sifive,clint, the DT may be like this:

mswi: interrupt-controller@94000000 {
compatible = "sophgo,sg2042-clint", "thead,c900-clint";
interrupts-extended = <&cpu1intc 3>;
reg = <0x94000000 0x00010000>;
};

timer: timer@ac000000 {
compatible = "sophgo,sg2042-clint", "thead,c900-clint";
interrupts-extended = <&cpu1intc 7>;
reg = <0xac000000 0x00010000>;
};

Since the address of mswi and timer are different, it is hard to merge
them directly. So we need two DT nodes to handle both devices.
If we use this DT for SBI, it will parse the mswi device in the timer
initialization as the compatible string is the same, so will mswi.
As they are different devices, this incorrect initialization will cause
the system unusable.

There is a more robust ACLINT spec. can handle this situation, but
the spec. seems to be abandoned and will not be frozen in the predictable
future.

So it is not the time to add ACLINT spec in the kernel bindings. Instead,
using vendor bindings is more acceptable.

Add new vendor specific compatible strings to identify timer of sg2042
clint.

Subject: [PATCH v4 08/10] riscv: dts: add initial Sophgo SG2042 SoC device tree

From: Chen Wang <[email protected]>

Milk-V Pioneer motherboard is powered by SG2042.

SG2042 is server grade chip with high performance, low power
consumption and high data throughput.
Key features:
- 64 RISC-V cpu cores
- 4 cores per cluster, 16 clusters on chip
- More info is available at [1].

Currently only support booting into console with only uart,
other features will be added soon later.

This is the correct patchset, please review this one. Because my
incorrect operation resulted in two patchsets with the same name being
sent earlier, but they were incomplete. Sorry for the confusion.

Thanks,

[10/10] riscv: defconfig: enable SOPHGO SoC
https://git.kernel.org/conor/c/a4bbe6e3d9f6

b4 is confused, but I applied the whole series, temporarily, to a
"sophgo" branch. IIRC I asked for the defconfig patch to have
savedefconfig run it it, so I did that and amended the patch.
More notably, I changed the commit message for the aclint patch, to
drop the discussion about incorrect use of the sifive,clint compatible.
That meant that 90% of the commit message vanished, so I'd like you guys
to take a look and see if the new text works for you.
If it is acceptable, I'll merge in both this series and the milkv duo
stuff. Acks on that series from one of the folks added as a maintainer
here are still appreciated and will be applied.

Thanks,
Conor.

-1 may not be correct, is machine external interrupt(id: 11) supported?

Thanks

Just double-checked with sophgo IC engineers, sg2042 plic supports
external interrupt, so 11 should be better, I will try to fix this in v5.

Thanks for your kindly reminder, Jisheng.

Thanks, I'll pay attention on this next time.

Due to commnents from Jisheng, I want to continue changes DTS on plic
node, I have submitted v5 patchset, can you please pick and merge with
this? v5 also contains the changes you have made on "sophgo" branch.

Thanks,

Chen
