[PATCH v1 0/2] build full dtbs for BananaPi R3/R4(Pro)

[Frank Wunderlich]

From: Frank Wunderlich <frank-w@public-files.de>

Build devicetree binaries for testing overlays and providing users
full dtb without using overlays for Bananapi R4 (pro) variants.

It is not required to build all possible combinations, only for
common usecases and to test if all overlays can be applied.

This series is based on

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: attempting to guess base-commit...
 Base: tags/next-20251119 (exact match)
 Base: tags/next-20251119 (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/mediatek/' for 20251119175124.48947-1-linux@fw-web.de:

scripts/Makefile.dtbs:20: .dtbo is not applied to any base: mt8395-radxa-nio-12l-8-hd-panel.dtbo

This looks like still not being applied and now it is a warning in
Linus' tree.

Can this be applied and sent as fixes?

Best regards,
Krzysztof

afair the series was sent after the pull-request from angelo and maybe 
he waited
for an ack from you/rob before applying ;)

if it helps i collected the commits for (possibly) sending as fix

Fixes: a58c36806741 ("arm64: dts: mediatek: mt7988a-bpi-r4pro: Add mmc 
overlays")
Fixes: dec929e61a42 ("arm64: dts: mediatek: mt7988a-bpi-r4-pro: Add PCIe 
overlays")
Fixes: 714a80ced07a ("arm64: dts: mediatek: mt7988a-bpi-r4: Add dt 
overlays for sd + emmc")
Fixes: 312189ebb802 ("arm64: dts: mt7986: add overlay for SATA power 
socket on BPI-R3")
Fixes: 8e01fb15b815 ("arm64: dts: mt7986: add Bananapi R3")

There's still one warning remaining after applying this series which I reported:

scripts/Makefile.dtbs:20: .dtbo is not applied to any base:
mt8395-radxa-nio-12l-8-hd-panel.dtbo

It's fixed in my original patch. Can you all take that and drop the bpi hunks.

FWIW:

Since there's been no movement on this, I've applied this series and the 
other patch and will send to Linus today.
