[PATCH 0/7] ARM: dts: exynos: Remove skeleton.dtsi usage and fix memory node DTC warnings

[Javier Martinez Canillas]

Hello Krzysztof,

This series removes the usage of the skeleton.dtsi in all the Exynos dts,
which allows to get rid of the DTC warnings about a mismatch between the
memory nodes' unit names and reg properties.

Patches are pretty trivial and shouldn't cause functional changes AFAIK,
but only the Exynos5 changes have been tested. The others patches were
just built tested.

Best regards,
Javier

[PATCH 1/7] ARM: dts: exynos: Add missing memory node for Exynos5440 boards

[Javier Martinez Canillas]

The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").

These also applies to ARM and it will also allow to get rid of the
following DTC warnings in the future:

"Node /memory has a reg or ranges property, but no unit name"

But these boards don't have a memory node defined, so removing the
skeleton.dtsi inclusion in exynos4.dtsi will cause a change in the
compiled DTB. Add a dummy memory node so the compiled DTB doesn't
change if the skeleton.dtsi is removed from exynos4.dtsi.

Eventually the correct starting addresses and sizes should be used
but I didn't find that information.

I think that this node deserves a FIXME comment.

You mean extnos5440.dtsi?

This looks okay, but the default size and address cells won't be
present. Won't that be a problem?

Yes, I meant exynos5440.dtsi, it's a commit message copy and paste error.
Thanks for pointing out, I'll fix it in v2.

They will be present since at this point exynos5440.dtsi is still including
exynos5440.dtsi, we are just overriding the memory node with the same values
than skeleton.dtsi so this can be removed later in patch 7/7.

I don't get it. exynos5440.dtsi does not set size/address cells in top node.

Sorry, maybe I'm misunderstanding your question. The size/address cells are set
in the top node by exynos5440.dtsi including the skeleton.dtsi (since these are
set in that included dtsi).

IOW, scripts/dtc/dtx_diff doesn't show differences for these exynos5440 DTB

Where? Nothing in my sources...

Maybe these are also the default values so no differences... stating
them explicitly would be useful.

No, I meant that these are set by the fact that exynos5440.dtsi is including
the skeleton.dtsi, since the dtsi set these properties in the top node.

I could do it in this patch... but I don't see why that should be needed since:

a) All the others Exynos SoC dtsi file don't explicitly set these properties
   since are set by skeleton.dtsi when including it. So not adding them keeps
   exynos5440.dtsi consistent with the other SoC dtsi.

b) Adding those to the Exynos SoC dtsi when removing the skeleton.dtsi is done
   in a later patch of this series. Again, making it consistent with all the
   Exynos SoC dtsi since none will include skeleton.dtsi anymore.

Ah, I missed it. The 'b' is the solution I wanted so everything is fine.

[PATCH 2/7] ARM: dts: exynos: Remove skeleton.dtsi usage for Exynos3

[Javier Martinez Canillas]

The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").

These also applies to ARM and it will also allow to get rid of the
following DTC warnings in the future:

"Node /memory has a reg or ranges property, but no unit name"

The disassembled DTB are almost the same besides an empty chosen
node being removed and nodes reordered, so it should not have
functional changes.

[PATCH 4/7] ARM: dts: exynos: Remove skeleton.dtsi usage for Exynos5

[Javier Martinez Canillas]

The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").

These also applies to ARM and it will also allow to get rid of the
following DTC warnings in the future:

"Node /memory has a reg or ranges property, but no unit name"

The disassembled DTB are almost the same besides an empty chosen
node being removed and nodes reordered, so it should not have
functional changes.

I think this is a common problem, not only Exynos-specific, so I would
prefer to stick to common pattern. Either all DTS/DTSI include skeleton
or none of them.

That's correct.

The idea is to get rid of skeleton.dtsi [0], but that will of course take
time until the dtsi is removed from all the files. So this patch is a step
in the right direction so at least Exynos is not a blocker to remove it.

Krzysztof's point is valid.  If you are going to convert all DTS/DTSI
then it is okay to apply Exynos specific changes, otherwise the code
should stay as it is currently.

Exynos won't be a blocker since we have your patches now and they can
be applied when/if needed ;)..

Sorry but I disagree. I see no reasons to need this to be an atomic, rather
than incremental change. Deprecated things are usually handled by removing
the usage and once there are no users, finally removing them.

Also, each subsystem maintainer should carry the patches for their platform
so it can't be a kernel wide change anyways and most likely split by kernel
releases.

Yes, given that there is agreement on the direction and people are aware
of the needed changes.  This doesn't seem to be a case yet as there is
no comment in skeleton.dtsi about being deprecated and other platforms'
Maintainers are not aware of the need for the change.
