[PATCH] arm64: dts: altera: move all SoCFPGA device trees from dts/intel

[PATCH] arm64: dts: altera: move all SoCFPGA device trees from dts/intel

[evon.chiam]

From: "Chiam, Evon" <evon.chiam@altera.com>

The dts/intel/ directory contains two distinct families:
- Altera SoCFPGA platforms (Stratix 10, Agilex, Agilex5, Agilex72,
  Agilex7M, N5X)
- Intel Keembay

All Altera SoCFPGA device trees already have a home in dts/altera/
(Stratix 10 has been there since the directory was introduced). Move
the remaining SoCFPGA DTS/DTSI files from dts/intel/ to dts/altera/
to consolidate all Altera SoCFPGA device trees under a single
directory. Only the Keembay files remain in dts/intel/.

All inter-file includes are relative so no include paths need to
change. The set of DTBs produced by dtbs_install is unchanged; they
are simply built from dts/altera/ instead of dts/intel/.

No compatible strings or file contents are modified; this is a
rename-only change.

This patch is a follow-up to the Agilex72 DTS series [Link above].
Reviewer feedback noted that moving only the Agilex72 files from
dts/intel/ was confusing since all other files there are also Altera
SoCFPGA. This patch moves all SoCFPGA device trees to dts/altera/,
leaving only the Keembay files in dts/intel/.

No compatible strings or file contents are modified; this is a
rename-only change.

Re: [PATCH] arm64: dts: altera: move all SoCFPGA device trees from dts/intel

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Medium] Silent change to the deployed dtbs_install path for the migrated dtbs.
- [Low] Stale MAINTAINERS entry scopes arch/arm64/boot/dts/intel/ to SoCFPGA maintainers.

commit 49f800875761e8815d7059a16da432b877f9c50f
Author: Chiam, Evon <evon.chiam@altera.com>

arm64: dts: altera: move all SoCFPGA device trees from dts/intel

This commit moves all Altera SoCFPGA device trees from dts/intel/ to
dts/altera/, leaving only the Keembay platform files in dts/intel/. The
move involves renaming the files and updating the respective Makefiles.

Link: https://lore.kernel.org/all/cd16fb78-551e-4630-83d6-a44a68e2e411@kernel.org/

>     Move the remaining SoCFPGA DTS/DTSI files from dts/intel/ to dts/altera/
>     to consolidate all Altera SoCFPGA device trees under a single
>     directory. Only the Keembay files remain in dts/intel/.

[Severity: Low]
Does this leave a stale entry in the MAINTAINERS file?

The SoCFPGA architecture entry currently covers F: arch/arm64/boot/dts/intel/.
Since only Keembay files remain there, will this falsely CC SoCFPGA maintainers
on patches modifying Keembay platforms?

[Severity: Medium]
Will this implicitly change the deployed path during dtbs_install?

Running make dtbs_install on ARM64 typically mirrors the source vendor
directory structure. Compiling these dtbs from the altera/ Makefile would
shift their target installation directory from intel/ to altera/.

Could this cause bootloaders (like U-Boot) or deployment scripts that have
hardcoded configurations expecting the intel/ vendor prefix to fail to find
the DTB and fail to boot? This seems to contradict the commit message's claim
that "The set of DTBs produced by dtbs_install is unchanged".

Nit: replace "device trees" in your commit header with either "support" 
or "files" . The "dts" in the header is already saying these are changes 
to device trees.

Also replace "from dts/intel" to "to dts/altera".

Fixed the subject in v2 and reworded it as suggested.
