NPU and i2c3 + FUSB302 addition for Radxa Zero 2

[PATCH 0/2] NPU and i2c3 + FUSB302 addition for Radxa Zero 2

Posted by Ricardo Pardini via B4 Relay 3 weeks, 4 days ago

This series adds a few things missing from the Radxa Zero 2:

1) NPU (etnaviv), just enable the node, similar to what was done for VIM3
2) i2c3 (also exposed on the 40-pin header) and the FUSB302 at 0x22

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade

This patch series was applied (using b4) to base:
 Base: 0f61b1860cc3f52aef9036d7235ed1f017632193 (use --merge-base to override)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

New warnings running 'make CHECK_DTBS=y for arch/arm64/boot/dts/amlogic/' for 20260114-arm64-dts-amlogic-radxa-zero2-additions-v1-0-8b5cdf328fde@pardini.net:

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.20/arm64-dt)

[1/2] arm64: dts: amlogic: Enable the npu node on Radxa Zero 2
      https://git.kernel.org/amlogic/c/29deec49146162d06b17739c627d062191e03814
[2/2] arm64: dts: amlogic: add the type-c controller on Radxa Zero 2
      https://git.kernel.org/amlogic/c/8f5aa8d444d1d200715c36a8f072054a49bfb410

These changes has been applied on the intermediate git tree [1].

The v6.20/arm64-dt branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.

In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].

The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.

If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.

You went quite fast, but this has warnings. See also Rob's bot response.
