[PATCH v6 00/10] Axiado AX3000 SoC and Evaluation Board Support

[PATCH v6 00/10] Axiado AX3000 SoC and Evaluation Board Support

[Harshit Shah]

This patch series adds initial support for the Axiado AX3000 SoC and its
evaluation board.

The AX3000 is a multi-core system-on-chip featuring four ARM Cortex-A53
cores, secure vault, hardware firewall, and AI acceleration engines. This
initial support enables basic bring-up of the SoC and evaluation platform
with CPU, timer, UART, and I3C functionality.

The series begins by adding the "axiado" vendor prefix and compatible
strings for the SoC and board. It then introduces the device tree files
and minimal ARCH_AXIADO platform support in arm64.

Patch breakdown:
  - Patch 1 add the vendor prefix entry
  - Patch 2 document the SoC and board bindings
  - Patch 3 convert cdns,gpio.txt to gpio-cdns.yaml
  - Patch 4 add binding for ax3000 gpio controller
  - Patch 5 add binding for ax3000 uart controller
  - Patch 6 add binding for ax3000 i3c controller
  - Patch 7 add Axiado SoC family
  - Patch 8 add device tree for the ax3000 & ax3000-evk
  - Patch 9 add ARCH_AXIADO in defconfig
  - Patch 10 update MAINTAINERS file

Note: A few checkpatch.pl warnings appear due to DT binding conversions and
MAINTAINERS update. The binding conversion and includes were kept together in 
patch 3/10 due to their close relationship, but we are happy to split them if 
preferred.

Feedback and suggestions are welcome.

Hi all,

This patch series was reviewed by Krzysztof, and I am wondering if it’s 
queued for the next merge window. Thanks in advance!

It's not, unless you received clear notice about it. Please read
maintainer soc profile how to send patches for merging.

Thank you Krzysztof for the reference.

We went through maintainer-soc.rst 
(https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/maintainer-soc.rst?h=v6.16-rc1#n73) 


It mentions about the special case where "Introducing a completely new 
SoC platform." we can submit patches to soc@kernel.org directly.

However I see two different points in the doc.

1. Submitting patches directly to soc@kernel.org with email

2. There is also mention about the "Branches and Pull requests"

(https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/maintainer-soc.rst?h=v6.16-rc1#n186). 


I think if we need to use this approach then we need to create a new 
branch on soc and create a pull request based on the same. (with the soc 
tree[1])


We are not sure if we should follow which method for this purpose. Can 
you please help on the same? Apologies for too long questions.

You do not create branches on other poeple's trees (like soc). You
create branch on your own tree.

You can go with 1 or 2, up to you, I don't know which one is preferred
by Arnd for new boards.

Yes, ideally the base should be -rc1, as for any other pull request.

Separate patches (1) tend to work better for the first contribution
from a new maintainer, since there is less to know in advance.

Please use soc@lists.linux.dev, we are trying to phase
out the old alias (both work the same right now).

soc@lists.linux.dev is already in CC. Shall I resend the patches keeping in To?

[Note: I checked locally and able to apply these patchset to

[PATCH v6 00/10] Axiado AX3000 SoC and Evaluation Board Support

[Harshit Shah]

-------------------------------
Hello SoC maintainers,

This patch series adds initial support for the Axiado AX3000 SoC and its
evaluation board.

Change from v6
- Ran "b4 trailer -u" and add reviewed by Krzysztof

Add soc@lists.linux.dev in the to list and send this series again as per 
suggestion by Krzysztof and Arnd. Thank you.

Checked locally and able to apply these patchset to soc git.
(git/soc/soc.git, for-next, checked commit: 7dfbf3176d886ff9a0c7786942d3a89809d0641e)

Sorry for late request, please consider this series for the 6.17.

The AX3000 is a multi-core system-on-chip featuring four ARM Cortex-A53

  - Patch 8 add device tree for the ax3000 & ax3000-evk
  - Patch 9 add ARCH_AXIADO in defconfig
  - Patch 10 update MAINTAINERS file

Note: A few checkpatch.pl warnings appear due to DT binding conversions and
MAINTAINERS update. The binding conversion and includes were kept together in 
patch 3/10 due to their close relationship, but we are happy to split them if 
preferred.

[PATCH v6 02/10] dt-bindings: arm: axiado: add AX3000 EVK compatible strings

[Harshit Shah]

Add device tree binding schema for Axiado platforms, specifically the
AX3000 SoC and its associated evaluation board. This binding will be
used for the board-level DTS files that support the AX3000 platforms.

-	* first cell is the GPIO number.

-- gpio-controller: marks the device as a GPIO controller.
-- clocks: should contain one entry referencing the peripheral clock driving

-Optional properties:
-- ngpios: integer number of gpio lines supported by this controller, up to 32.
-- interrupts: interrupt specifier for the controllers interrupt.
-- interrupt-controller: marks the device as an interrupt controller. When
-	defined, interrupts, interrupt-parent and #interrupt-cells

-- interrupt-cells: should be 2.
