Add initial device tree for Renesas RZ/Five RISC-V CPU Core (AX45MP
Single).
RZ/Five SoC is almost identical to RZ/G2UL Type-1 SoC (ARM64) hence we
will be reusing r9a07g043.dtsi [0] as a base DTSI for both the SoC's.
r9a07g043f.dtsi includes RZ/Five SoC specific blocks.
Below are the RZ/Five SoC specific blocks added in the initial DTSI which
can be used to boot via initramfs on RZ/Five SMARC EVK:
- AX45MP CPU
- PLIC

The initial patch shouldn't be broken. Combine them together with the
minimal components and add others late. Don't separate the DTS files.

r9a07g043.dtsi [0] already exists in the kernel. r9a07g043.dtsi is
shared with the RZ/G2UL SoC (ARM64) and the RZ/Five SoC. There are two
more patches [1] which are required and are currently queued up in the
Renesas tree for v6.2 (Ive mentioned the dependencies in the cover
letter).

You could just move the below part to the second dtsi patch. Then
compile won't be broken.
clocks = <&cpg CPG_MOD R9A07G043_NCEPLIC_ACLK>;

The makefile for this directory is not added until the next patch right?
The compile shouldn't be broken here since it therefore cannot be
compiled?

These nodes are already present in the kernel [0] so the makefile
change in the next patch if made here still won't break the
compilation alone of SoC DTSI (included in dts).

Yeah I know, I did actually build the dtb ;)
I was just confused as to how Guo Ren had found a build issue with this
patch that the follow on patch would fix, when this dtsi is not
buildable in this patch.

Oh... Sorry, I screwed up. The
arch/arm64/boot/dts/renesas/r9a07g043.dtsi is not belonged to the

If you put a DTS without a makefile added, it's an unused code in the
repo. I still prefer to add them one by one and ensure every patch
could be properly compiled.
This patch series unnecessarily broke the compilation of the first patches.

Compile won't break at all, the CPG node [0] and the pinctrl node [1]
already exists in the kernel which is being re-used by this SoC DTSI.
... the include file above already exists in the kernel and is not
part of the next follow up patch.

Enable the minimal blocks required for booting the Renesas RZ/Five
SMARC EVK with initramfs.
Below are the blocks which are enabled:
- CPG
- CPU0
- DDR (memory regions)
- PINCTRL
- PLIC
- SCIF0
As we are reusing the RZ/G2UL SoC base DTSI [0], RZ/G2UL SMARC SoM [1] and
carrier [2] board DTSIs which enables almost all the blocks supported
by the RZ/G2UL SMARC EVK and whereas on RZ/Five SoC we will be gradually
enabling the blocks hence the aliases for ETH/I2C are deleted and rest
of the IP blocks are marked as disabled/deleted.

This should combine with the previous one, which makes the patch complete.

For easier review purposes we tend to have separate patches for SoC
and the board on ARM/64 which is what I have followed here. If you

Enable Renesas RZ/Five SoC config in defconfig. It allows the default
upstream kernel to boot on RZ/Five SMARC EVK board.
Alongside enable SERIAL_SH_SCI config so that the serial driver used by
RZ/Five SoC is built-in.

You forgot to refresh after moving ARCH_RENESAS in v5 of "riscv:
Kconfig.socs: Add ARCH_RENESAS kconfig option", and after relying on
ARCH_R9A07G043 in drivers/soc/renesas/Kconfig.

PM and GPIOLIB are auto-selected by ARCH_R9A07G043 (through ARCH_RZG2L)
resp. SOC_RENESAS, so they can be dropped. But it's better to do this
after the release of v6.2-rc1, when all pieces have fallen together.

Are you suggesting dropping it from defconfig?

Yes, but not right now, as that would make it depend on my
renesas-drivers-for-v6.2 branch to keep them enabled.

I was wondering if that's required by other platforms though.
CONFIG_PM was added for VIRT machine and GPIOLIB for HiFive.

Does that matter? They would still get it, as long as they use the
defconfig.
If you want to remove unwanted platforms from your configuration,
you do that in the .config file, not in the defconfig file.
If you have CONFIG_PM=y in your .config, it will be retained.

Yes, I did, but not right now, only after v6.2-rc1.
- Once the defconfig has CONFIG_ARCH_R9A07G043=y, ARCH_RZG2L will
be auto-selected (commit ebd0e06f3063cc2e ("soc: renesas: Identify
RZ/Five SoC") is already upstream), and CONFIG_PM as well. So there
is no longer a need for the defconfig to enable it explicitly.
- Once the defconfig has CONFIG_ARCH_RENESAS=y, SOC_RENESAS will
be auto-selected, but auto-selecting CONFIG_GPIOLIB depends on commit
b3acbca3c80e6124 ("soc: renesas: Kconfig: Explicitly select GPIOLIB and
PINCTRL config under SOC_RENESAS") is only in renesas-drivers-for-v6.2.
Please run "make savedefconfig", and compare the generated defconfig
with arch/riscv/configs/defconfig.
Gr{oetje,eeting}s,
Geert

Hey,
Looks like you've got a pair of warnings here from dtbs_check. I tested
this on top of 20221028's next, with the three branches below merged in,
hopefully my merges aren't the source of them:
linux/arch/riscv/boot/dts/renesas/r9a07g043f01-smarc.dtb: pinctrl@11030000: 'interrupt-controller' is a required property
From schema: Documentation/devicetree/bindings/pinctrl/renesas,rzg2l-pinctrl.yaml

From schema: linux/Documentation/devicetree/bindings/pinctrl/renesas,rzg2l-pinctrl.yaml
With this sorted, whatever wasn't already is now:
Reviewed-by: Conor Dooley <conor.dooley@microchip.com>
Thanks for putting up with my messing around re: kconfig symbols and I
am glad that we ended up being able to share the dts across archs in the
end, so thanks to everyone involved in that :)

Thanks for the review and test. The warnings above are coming from [0]
as support for IRQC is missing, once that is added the warnings should
go away.

Right. I merged in the stuff in Geert's trees & I don't think I saw any
pending patches in the cover that I missed. Is there something else that
adds the support that's not going to make v6.2? I got rid of all the
dtbs_check warnings for v6.1 and I'd really like to keep things that
way!

Sorry that pacth wasn't posted yet so I hadn't mentioned it in the
cover letter. I'll make sure I get it posted asap and merged for v6.2.

I have got the patches out [0] which will fix the warnings seen above.
BTW on the riscv patchwork I see status as fail "Patch does not apply
to for-next" does that mean I need to resend re-basing on your tree?
[0] https://patchwork.kernel.org/project/linux-renesas-soc/cover/20221107175305.63975-1-prabhakar.mahadev-lad.rj@bp.renesas.com/

Cool, thanks :)

Nah, I though that Geert would be applying this patchset, no?
If that's the case, it only needs to apply to his tree.
Geert, are you waiting for an ack from Palmer?

I can take:
- [PATCH v5 4/7] riscv: dts: renesas: Add initial devicetree for
Renesas RZ/Five SoC
- [PATCH v5 5/7] riscv: dts: renesas: Add minimal DTS for Renesas
RZ/Five SMARC EVK
- [PATCH v5 6/7] MAINTAINERS: Add entry for Renesas RISC-V
(4/7 and 5/7 depend on my renesas-arm-dt-for-v6.2 branch) and funnel
them to the SoC-people.
I can take
- [PATCH v5 3/7] riscv: Kconfig.socs: Add ARCH_RENESAS kconfig option
- [PATCH v5 7/7] riscv: configs: defconfig: Enable Renesas RZ/Five SoC
with an ack from Palmer.
The rest
- [PATCH v5 1/7] dt-bindings: riscv: Sort the CPU core list alphabetically
- [PATCH v5 2/7] dt-bindings: riscv: Add Andes AX45MP core to the list
should probably go through the riscv tree, to avoid merge conflicts
when support for other SoCs is added?
Thanks!

Geert

Or depending on the outcome of [0], maybe I take the dt-binding stuff?
Either way, looks like an ack from Palmer is needed for 3 & 7. I can do
the video call version of a ping on that tomorrow at the pw sync thing.

Geert was mentioning taking these though one of his trees, that works
for me so
Acked-by: Palmer Dabbelt <palmer@rivosinc.com>
Happy to do a shared tag or whatever, but I think we can just skip that
here. The only conflicts would be defconfig and Kconfig.socs, but I
don't think anything big is in the works for either -- unless Conor was
planning on re-spinning that Kconfig.socs rework?
Thanks!

Uh, nah. I've got a wee bit (the removal of selects) that is "ready" but
there's zero urgency so it can wait for after v6.2-rc1. I don't think
it'd conflict anyway. The rest of it I need to sort out a v1 of, but I've
been distracted. Should be safe to take the defconfig & Kconfig.socs stuff
in terms of me doing anything.
Geert, would you be able to apply the first two patches on top of
v6.1-rc1 just in case, as you mentioned previously, it needs to become
part of a shared branch? Seems unlikely at this point in the cycle
though.
Thanks,
Conor.
