[PATCH 0/5] remove label = "cpu" from DSA dt-binding

[PATCH 0/5] remove label = "cpu" from DSA dt-binding

[Arınç ÜNAL]

Hello folks,

With this patch series, we're completely getting rid of 'label = "cpu";'
which is not used by the DSA dt-binding at all.

Information for taking the patches for maintainers:
Patch 1: netdev maintainers (based off netdev/net-next.git main)
Patch 2-3: SoC maintainers (based off soc/soc.git soc/dt)
Patch 4: MIPS maintainers (based off mips/linux.git mips-next)
Patch 5: PowerPC maintainers (based off powerpc/linux.git next-test)

I've been meaning to submit this for a few months. Find the relevant
conversation here:
https://lore.kernel.org/netdev/20220913155408.GA3802998-robh@kernel.org/

Here's how I did it, for the interested (or suggestions):

Find the platforms which have got 'label = "cpu";' defined.
grep -rnw . -e 'label = "cpu";'

Remove the line where 'label = "cpu";' is included.
sed -i /'label = "cpu";'/,+d arch/arm/boot/dts/*
sed -i /'label = "cpu";'/,+d arch/arm64/boot/dts/freescale/*
sed -i /'label = "cpu";'/,+d arch/arm64/boot/dts/marvell/*
sed -i /'label = "cpu";'/,+d arch/arm64/boot/dts/mediatek/*
sed -i /'label = "cpu";'/,+d arch/arm64/boot/dts/rockchip/*
sed -i /'label = "cpu";'/,+d arch/mips/boot/dts/qca/*
sed -i /'label = "cpu";'/,+d arch/mips/boot/dts/ralink/*
sed -i /'label = "cpu";'/,+d arch/powerpc/boot/dts/turris1x.dts
sed -i /'label = "cpu";'/,+d Documentation/devicetree/bindings/net/qca,ar71xx.yaml

Restore the symlink files which typechange after running sed.

Hi Arınç

So your plan is that each architecture maintainer merges one patch?

That is fine, but it is good to be explicit, otherwise patches will
fall through the cracks because nobody picks them up. I generally use

Initially, I sent this series to soc@kernel.org to take it all but Rob 
said it must be this way instead.

I'm sending a more specific mail to make sure this series doesn't fall 
through the cracks like Andrew said. I'd like this merged this week 
before the merge window closes.

Jakub, please take patch 1.
Arnd, please take patch 2 and 3.
Thomas, please take patch 4.
Michael, please take patch 5.

Adding Pali to Cc.

These were only recently updated in commit:

  8bf056f57f1d ("powerpc: dts: turris1x.dts: Fix labels in DSA cpu port nodes")

Which said:

  DSA cpu port node has to be marked with "cpu" label.

But if the binding doesn't use them then I'm confused why they needed to
be updated.

cheers

IMHO the best solution if the patches are truly independent is to send
them independantly to each maintainer. That way there's no confusion
about whether someone else will take the series.

It's also simpler for maintainers to apply a single standalone patch vs
pick a single patch from a larger series.

cheers

I was told by Marek (CCed) that DSA port connected to CPU should have
label "cpu" and not "cpu<number>". Modern way for specifying CPU port is
by defining reference to network device, which there is already (&enet1
and &enet0). So that change just "fixed" incorrect naming cpu0 and cpu1.

So probably linux kernel does not need label = "cpu" in DTS anymore. But
this is not the reason to remove this property. Linux kernel does not
use lot of other nodes and properties too... Device tree should describe
hardware and not its usage in Linux. "label" property is valid in device
tree and it exactly describes what or where is this node connected. And
it may be used for other systems.

So I do not see a point in removing "label" properties from turris1x.dts
file, nor from any other dts file.

Well, it seems like a bit of an abuse of 'label' to me. 'label' should 
be aligned with a sticker or other identifier identifying something to a 
human. Software should never care what the value of 'label' is.

But it already does. "label" property is used for setting (initial)
network interface name for DSA drivers. And you can try to call e.g.
git grep '"cpu"' net/dsa drivers/net/dsa to see that cpu is still
present on some dsa places (probably relict or backward compatibility
before eth reference).

I agree with you that in this case it is abuse. But I would not say that
software should not care about "label". I think that software should
care about "label" but only in situation in which it presents
information to user. So if user wants to see device with labels *ABC*
(meaning show me anything which stickers contains substring ABC) then
software should filter devices and turns that with asked label.

The main problem here is _existing_ software. New software should really
do not use cpu label for deciding if network port is connected to cpu or
not and it should be designed correctly. But you cannot change nor fix
old / existing software...

The worst thing which can be done is breaking updated version of (old)
software. Prevention is always testing software and in this case testing
on the real hardware. I know, it is hard as developers do not have
such lot of hardware devices and configurations.

Can you try to eliminate the word "probably" from the information you
transmit and be specific about when did the DSA binding parse or require
the 'label = "cpu"' property for CPU ports in any way?

As Jonas (on CC) pointed out, I only see this being used in the swconfig 
b53 driver which uses the label to identify the cpu port.

https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=target/linux/generic/files/drivers/net/phy/b53/b53_common.c;h=87d731ec3e2a868dc8389f554b1dc9ab42c30be2;hb=HEAD#l1508

Maybe this got into DSA dt-bindings unchecked before it was decided to 
move forward with DSA instead of swconfig on Linux.
