linux-next: build warnings after merge of the ti tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 613 bytes --]

Hi all,

[I may have missed this yesterday, sorry]

After merging the ti tree, today's linux-next build (arm64 defconfig)
produced these warnings:

arch/arm64/boot/dts/ti/k3-am642-evm-nand.dtso:65.8-140.3: Warning (avoid_default_addr_size): /fragment@3/__overlay__: Relying on default #address-cells value
arch/arm64/boot/dts/ti/k3-am642-evm-nand.dtso:65.8-140.3: Warning (avoid_default_addr_size): /fragment@3/__overlay__: Relying on default #size-cells value

Introduced by commit

  45a0c06571e1 ("arm64: dts: ti: am642-evm: Add overlay for NAND expansion card")

Thanks for the report. I will drop the offending comment.

Roger,

Sorry, this would need to be fixed in dtc or need exception from DT
maintainers to ignore the warnings.

Please don't drop this patch as the issue is not with the patch but with
the dtc tool itself.

As this is a DT overlay there is no way to specify address-cells/size-cells
of parent here. This will be resolved only after merge with base tree.

This will be fixed in next dtc sync.

Roger, build warnings are a strict NO,NO for kernel. Lets bring in the
series *after* the dtc sync is complete.

Hi Rob,

Following commit from dtc is required to resolve this issue.

afbddcd418fb ("Suppress warnings on overlay fragments")

FYI. Another patch of similar nature is on its way and will also require the
above commit to DTC.

That is from 2018, so it's been in the kernel's dtc for a long time.

I believe what you need is the patch I referenced which hasn't been
applied upstream.

You'll need to fix dtc first.

Oh, my bad. I saw your Reviewed-by tag and assumed the patch was already upstream.
