[PATCH 00/16] Add support for the Axis ARTPEC-8 SoC

[ksk4725]

From: SeonGu Kang <ksk4725@coasia.com>

Add basic support for the Axis ARTPEC-8 SoC.
This SoC contains four Cortex-A53 CPUs and other several IPs.

Patches 1 to 10 provide the support for the clock controller,
which is similar to other Samsung SoCs.

The remaining patches provide pinctrl support and
initial device tree support.

[PATCH 01/16] dt-bindings: clock: Add CMU bindings definitions for ARTPEC-8 platform

[ksk4725]

From: Ravi Patel <ravi.patel@samsung.com>

Add device tree clock definitions constants for ARTPEC-8 platform.
ARTPEC-8 platform has separate instances for each particular CMU.
So clock IDs in this bindings header also start from 1 for each CMU block.

+description: |
+  ARTPEC-8 clock controller is comprised of several CMU units, generating
+  clocks for different domains. Those CMU units are modeled as separate device
+  tree nodes, and might depend on each other. The root clock in that root tree
+  is an external clock: OSCCLK (25 MHz). This external clock must be defined
+  as a fixed-rate clock in dts.
+
+  CMU_CMU is a top-level CMU, where all base clocks are prepared using PLLs and
+  dividers; all other clocks of function blocks (other CMUs) are usually
+  derived from CMU_CMU.
+
+  Each clock is assigned an identifier and client nodes can use this identifier
+  to specify the clock which they consume. All clocks available for usage
+  in clock consumer nodes are defined as preprocessor macros in
+  'include/dt-bindings/clock/axis,artpec8-clk.h' header.

Why? No, don't do that, even if clock frequency of xxti is missing. Look
at other SoCs.

This belongs to the previous patch rather. You can split board DTS, though.

We sort nodes by pin names, usually. What sorting rule you applied here?

You should explain here (and in DTS patches or the bindings) the
hardware, that this is Samsung SoC.

You could also explain the differences from Exynos and proposed handling
of patches (because this is odd)

Also, entire patchset has wrong and incomplete SoBs. Your SoB is missing
everywhere, others have wrong order.

Please read submitting patches first.

Confusing order, unless you really understand this, but considering you
did not add your own SoB I claim you do not understand this. What does
Ravi's SoB mean here?

reg goes second, after compatible (Samsung bindings are not the best

All these names should be changed to match what is the input. Look at
latest bindings, we moved away from that style.

I'm trying to understand the SoC family tree here. I see that
you have an entry for ARTPEC SoCs above it, which currently
covers artpec6 (Cortex-A9, apparently not Samsung based).

Is the reason for having two entries here that artpec6/7 and
artpec8/9 are two separate SoC families, or is this just because
they are using 32-bit and 64-bit cores, respectively?

I would prefer to be less fine-grained here, especially as
it seems that ARTPEC9 is again quite similar to ARTPEC8, as
far as I can guess from public information.

Could you fold both entries into a single ARCH_ARTPEC?

These should be entirely different families. Artpec6 was not done by
Samsung and this one - Artpec 8 - is basically Samsung SoC, just like
they did designs for Tesla and Google GS101.

I don't know about Artpec 9.

All this should be explained in DTS or bindings commit msg, btw.

So far ARCH_ARTPEC = ARCH_ARTPEC8, so obviously it can be folded. I
don't know if Artpec 9 will ever be upstreamed. This Artpec 8 is like 4
or 5 year effort - they sent first patches some years ago, but DTS was
not ready. Therefore I think we should not assume there will be Artpec 9
yet. If it comes, we can always split things.

Out of the 9 patches there are 7 patches related to "CMU" without
any explanation or even expansion of this acronym.

Camera Management Unit? I think I'm not supposed to
guess. Is is an Axis-custom piece of hardware? (Would make
sense.)

Please expand this acronym and state clearly that (if this
is a correct assumption) that you are not supplying any
bindings and even less a driver for the "CMU" thing, just the
clocks. (That's fine the actual CMU can come later, but
it should be clear *what* it is.)

Yours,
Linus Walleij

Ok, I will modify clock-names to "bus" and "dlp" and will update at the

My intention here is to split the clock changes so as to make smaller
patches.
I will squash patch 04 to 10 and make a single clock driver patch.

This Custom SoC is owned by the Axis (OEM) and manufactured by the
Samsung (ODM). It has standard Samsung specific IP blocks.
Regarding SoB, sorry I missed to add submitter's signoff. We will take

The original intention for conversion here is to satisfy the dt-
bindings check warnings.
I will break this patch into 2 patches where 1st will be conversion
from txt to yaml and 2nd will be adding new board.

It is designed by Samsung. It is Samsung SoC.

Anyway, don't explain to me, but in your patchset.

Is it fine if I merge the list with existing ARTPEC entry?
Samsung and Coasia entry can be removed from list as Axis will be only
maintaining the ARTPEC-8 SoC in future.
Please suggest your opinion here.

Should I move the axis folder inside exynos just like google did? In
that case we don't need separate ARCH entry anymore.
Or should I follow the tesla FSD style to add axis folder outside
exynos? In that case I will keep ARCH_ARTPEC entry only.
Please suggest your opinion here.

Ok, I will move the ranges property next to compatible.

Ok, I will add “axis,artpec8-mct” in the compatible string and rename
the node name to "timer".

You did not describe the hardware really. Neither in commit msg, nor in

Hi Krzysztof,

Thank you for your review comments on the ARTPEC-8 platform patches.
I'd like to add more context about the ARTPEC-8 SoC to help clarify its
relationship with Exynos.

Here are the key details about ARTPEC-8:
   - Manufactured by Samsung Foundry
   - SoC architecture is owned by Axis Communications
	- On similar model as Tesla's FSD chip owned by Tesla and 
              manufactured and  by Samsung
   - IPs from both Samsung and Axis Communications

Samsung-provided IPs:
  - UART
  - Ethernet (Vendor: Synopsys)
       - Same IP has been integrated as integrated in FSD Chip
  - SDIO
  - SPI
  - HSI2C
  - I2S
  - CMU (Clock Management Unit)
       Follows same CMU HW architecture as Exynos SoC have
  - Pinctrl (GPIO)
  - PCIe (Vendor: Synopsys)
       Though Exynos, FSD, ARTPEC have same DesignWare Controller, 
       the glue/wrapper layer around DWC Core has differences across
       these SoCs. All manufactured by Samsung, but differences are there
       in HW design and for different products. For the same reason PCIe patch
       refactoring effort is being put by us [1] to streamline single Exynos driver
       which can support all Samsung manufactured SoCs having DWC PCIe controller.
      [1]: https://patchwork.ozlabs.org/project/linux-pci/patch/20250625165229.3458-2-shradha.t@samsung.com/

Axis-provided IPs:
    - VIP (Image Sensor Processing IP)
    - VPP (Video Post Processing)
    - GPU
    - CDC (Video Encoder)

As part of the upstreaming effort, Samsung and Coasia (DSP) team will work together
to upstream basic SoC support and Samsung IPs support.
The Axis team will be the primary maintainer for the ARTPEC-8 SoC codebase.

Given that ARTPEC-8 is a distinct SoC with its own set of IPs, we believe it's reasonable
to create a separate directory for it, similar to FSD.

We will remove Samsung and Coasia teams from the maintainers list in v2 and only
Axis team will be maintainer.

Maintainer list for previous generation of Axis chips (ARM based) is already present,
so this will be merged into that.

Please let us know if this explanation addresses your concerns. 
We'll update the commit message and cover letter accordingly.

Thanks,
Pankaj Dubey

So entire base of the SoC is Samsung.

Don't know what do you mean by "primary", but I want to be clear: this
classifies as Samsung SoC, so I will be maintaining and overlooking it
just like I maintain and take care about all Samsung SoCs. Otherwise you
will be introducing errors and warnings or, in best case different
style. And this already happened if I did not object!

Also SAME strict DT compliance profile will be applied. (see more on
that below)

No. It was a mistake for FSD to keep it separate why? Because there is
no single non-Samsung stuff there. I am afraid exactly the same will
happen there.

Based on above list of blocks this should be done like Google is done,
so it goes as subdirectory of samsung (exynos). Can be called axis or
artpec-8.

To clarify: Only this SoC, not others which are not Samsung.

A bit unexpected or rather: just use names of people who WILL be
maintaining it. If this is Jesper and Lars, great. Just don't add
entries just because they are managers.

Existing Artpec entry does not have tree mentioned, so if you choose
above, you must not add the tree, since the tree is provided by Samsung SoC.

OTOH, how are you going to add there strict DT compliance? Existing axis
is not following this, but artpec-8, as a Samsung derivative, MUST
FOLLOW strict DT compliance. And this should be clearly marked in
maintainer entry, just like everywhere else.

Yes, if we are saying this based on the core IPs (CMU, Pinctrl) and the fact that
it is manufactured by Samsung.

By "primary" I mean as it is product of Axis, and only Axis will be having access

I am not sure, why you are saying this as a mistake, in case next version of FSD
or ARTPEC is manufactured (ODM) by another vendor in that case, won't it
create problems? 

For example ARTPEC-6/7 (ARM based) have their own directories as "arch/arm/boot/dts/axis/"
These were not Samsung (ODM) manufactures SoCs. 

But ARTPEC-8/9 (ARM64) based SoCs are samsung manufactured. What if the next version say
ARTPEC-10 is not samsung manufactured, so different version of products (SoCs) from
same vendor (OEM), in this case Axis, will have code in separate directories and with different maintainers?

I will suggest to keep axis, knowing the fact that sooner after artpec-8 patches gets approved and merged
we have plan to upstream artpec-9 (ARM64, Samsung manufactured) as well.

As I said this is tricky situation, though artpec-8 is derivative of samsung, we can't confirm 
if future versions (> 9) will be samsung derivative. 

But this would be case for all such custom ASIC manufactured by samsung, so I would like to
understand how this will be handled?

My mistake that I agreed on that, based on promise that "there will be
non Samsung stuff" and that "non Samsung stuff" never happened.

No problems here. Non-Samsung Artpec/Axis soc will not go there. It will
go the top-level axis directory, just like artpec-6

It will be the same with Google Pixel for whatever they decide in the
future. dts/exynos/google/ + dts/google/.

I know that this is not ideal, but for me grouping samsung stuff
together is far more important, because there is much, much more to
share between two SoCs designed by Samsung, than Axis-9 and future
non-Samsung Axis-10. And I have `git grep` as argument:
git grep compatible -- arch/arm64/boot/dts/tesla/

and point me to any Tesla IP. Zero results.

I suggest to do the same as Google and when I say Google in this email,
I mean Pixel/GS101. Google was easier because there was no prior entry
and Axis has, so you will have two Axis entries. But I don't see how we
can add clean-dts profiles to the existing Axis entry, if you decide to
include Artpec-8 in that one.

Agreed. We did have a case where something gradually changed
instead of changing ODMs entirely:

Apple A4 was mostly an Exynos-family chip but A18 is not.
If Axis turns into the next Apple and ARTPEC-23 is far enough
removed from ARTPEC-9 to no longer fit into the same family
as Exynos/Tensor/FSD, we can still reconsider the decision
in a decade.

I am not authorized to comment on FSD's non Samsung stuff at this moment.
But I got your point.

Okay, understood. I assume Axis team will be fine with this approach.
Let me align with them internally and address all the review comments in v2.

Okay we will have separate dts profile aligned with Exynos DT compliance for
ARM64 based Axis SoCs which are manufactured by Samsung at this moment.

Just for the record, Axis has no problem in having the ARTPEC-8 / ARTPEC-9
in the Samsung directory, while the older ARTPEC-6 / ARTPEC-7 and
any other future chips will be separate.

[PATCH v2 00/10] Add support for the Axis ARTPEC-8 SoC

[Ravi Patel]

Add basic support for the Axis ARTPEC-8 SoC which contains
quad-core Cortex-A53 CPU and other several IPs. This SoC is an
Axis-designed chipset used in surveillance camera products such as
the AXIS Q1656-LE and AXIS Q3538-LVE.

This ARTPEC-8 SoC has a variety of Samsung-specific IP blocks and
Axis-specific IP blocks and SoC is manufactured by Samsung Foundry.

List of Samsung-provided IPs:
- UART
- Ethernet (Vendor: Synopsys)
- SDIO
- SPI
- HSI2C
- I2S
- CMU (Clock Management Unit)
- Pinctrl (GPIO)
- PCIe (Vendor: Synopsys)
- USB (Vendor: Synopsys)

List of Axis-provided IPs:
- VIP (Image Sensor Processing IP)
- VPP (Video Post Processing)
- GPU
- CDC (Video Encoder)

This patch series includes below changes:
- CMU (Clock Management Unit) driver and its bindings
- GPIO pinctrl configuration and its bindings
- Basic Device Tree for ARTPEC-8 SoC and boards

The patch series has been tested on the ARTPEC-8 EVB with
Linux v6.15-rc5 and intended to be merged via the `arm-soc` tree.

---
Changes in v2:
- Update SoB sections in all patches
- Update the copyright year to 2025
- Add CMU abbreviation description
- Merge dt-bindings patch 01 and 02 into single patch
- Modify yaml file to fit coding style in CMU
- Modify clock-names
- Reorder config macros to fit coding style
- Remove the unused macro in clock driver code
- Squash all clock driver patches (4 to 10) into single patch
- Split yaml conversion patch translation and add ARTPEC-8 SoC
- Remove "clock-frequency" property from cpu node in dtsi
- Remove the "status" property in dts and dtsi
- Reorder the DTS and pin nodes to follow the alphabetical and DTS coding style
- Change items property in axis.yaml
- Move dts files to exynos folder
- Removed ARCH_ARTPEC8 from platform Kconfig
- Add pattern in MAINTAINER file
- Merge dtsi and pinctrl dtsi file
- Split board dts file

Link to v1: https://lore.kernel.org/all/20250710002047.1573841-1-ksk4725@coasia.com/
NOTE: The first version has been sent by Coasia.
      After that, it has been agreed between Coasia and Samsung that Samsung will take
      ownership of upstreaming ARTPEC-8 and ARTPEC-9 platforms.

[PATCH v2 01/10] dt-bindings: clock: Add ARTPEC-8 clock controller

[Ravi Patel]

From: Hakyeong Kim <hgkim05@coasia.com>

Add dt-schema for Axis ARTPEC-8 SoC clock controller.

The Clock Management Unit (CMU) has a top-level block CMU_CMU
which generates clocks for other blocks.

Add device-tree binding definitions for following CMU blocks:
- CMU_CMU
- CMU_BUS
- CMU_CORE
- CMU_CPUCL
- CMU_FSYS
- CMU_IMEM
- CMU_PERI

+description: |
+  ARTPEC-8 clock controller is comprised of several CMU (Clock Management Unit)
+  units, generating clocks for different domains. Those CMU units are modeled
+  as separate device tree nodes, and might depend on each other.
+  The root clock in that root tree is an external clock: OSCCLK (25 MHz).
+  This external clock must be defined as a fixed-rate clock in dts.
+
+  CMU_CMU is a top-level CMU, where all base clocks are prepared using PLLs and
+  dividers; all other clocks of function blocks (other CMUs) are usually
+  derived from CMU_CMU.
+
+  Each clock is assigned an identifier and client nodes can use this identifier
+  to specify the clock which they consume. All clocks available for usage
+  in clock consumer nodes are defined as preprocessor macros in
+  'include/dt-bindings/clock/axis,artpec8-clk.h' header.

[PATCH v2 02/10] clk: samsung: Add clock PLL support for ARTPEC-8 SoC

[Ravi Patel]

From: Hakyeong Kim <hgkim05@coasia.com>

Add below clock PLL support for Axis ARTPEC-8 SoC platform:
- pll_1017x: Integer PLL with mid frequency FVCO (950 to 2400 MHz)
             This is used in ARTPEC-8 SoC for shared PLL

- pll_1031x: Integer/Fractional PLL with mid frequency FVCO
             (600 to 1200 MHz)
             This is used in ARTPEC-8 SoC for Audio PLL

FOUT calculation for pll_1017x and pll_1031x:
FOUT = (MDIV x FIN)/(PDIV x 2^SDIV) for integer PLL
FOUT = (((MDIV + KDIV)/65536) x FIN)/(PDIV x 2^SDIV) for fractional PLL

in ARTPEC-8 SoC:
 - CMU_CMU
 - CMU_BUS
 - CMU_CORE
 - CMU_CPUCL
 - CMU_FSYS
 - CMU_IMEM
 - CMU_PERI

Do not attach (thread) your patchsets to some other threads (unrelated
or older versions). This buries them deep in the mailbox and might
interfere with applying entire sets.

This will conflict with round_rate drop, so might need rebasing. Please

Thanks for review and pointing out.

Yes. You are right.
I will add GIC_CPU_MASK_SIMPLE(4) in next version as this uses GICv2 (gic-400) not GICv3.

This may be carried out from other exynos/fsd platforms

I found below 2 related links.

Thanks for review. Yes, I can see conflicts with below patch 
https://lore.kernel.org/linux-samsung-soc/20250811-clk-for-stephen-round-rate-v1-99-b3bf97b038dc@redhat.com/

Since merging strategy of round_rate patches are not clear as of now, will wait for couple of days before posting v3.
Request to review other patches also.
