[PATCH 0/3] dt-bindings: net: sunxi: Fix binding validation issues

[Samuel Holland]

These patches fix issues found when running `make dtbs_check` on sunxi
boards. I am not 100% sure about the change in the first two patches,
but I think I understand what is happening, and the change has the
desired effect. It fixes errors of the form:

  arch/arm/boot/dts/sun6i-a31s-colorfly-e708-q1.dtb: ethernet@1c30000:
  Unevaluated properties are not allowed ('mdio', 'reset-names',
  'resets', 'snps,fixed-burst', 'snps,force_sf_dma_mode', 'snps,pbl'
  were unexpected)

where all of the listed properties are defined in snps,dwmac.yaml.

The third patch fixes an unrelated omission in the sun8i-emac binding.

[PATCH 1/3] dt-bindings: net: sun7i-gmac: Fix snps,dwmac.yaml inheritance

[Samuel Holland]

The sun7i-gmac binding extends snps,dwmac.yaml, and should accept all
properties defined there, including "mdio", "resets", and "reset-names".
However, validation currently fails for these properties because the
local binding sets "unevaluatedProperties: false", and snps,dwmac.yaml
is only included inside an allOf block. Fix this by referencing
snps,dwmac.yaml at the top level.

[PATCH 3/3] dt-bindings: net: sun8i-emac: Add phy-supply property

[Samuel Holland]

This property has always been supported by the Linux driver; see
commit 9f93ac8d4085 ("net-next: stmmac: Add dwmac-sun8i"). In fact, the
original driver submission includes the phy-supply code but no mention
of it in the binding, so the omission appears to be accidental. In
addition, the property is documented in the binding for the previous
hardware generation, allwinner,sun7i-a20-gmac.

Document phy-supply in the binding to fix devicetree validation for the
25+ boards that already use this property.

I don't understand where is the problem and how does your patch solve
it. The old syntax is correct and your change does nothing, no fixing,
no impact. It actually looks like noop with big explanation :(

I must admit you're right that this hides the warning from dtbs_check,
but not because something in allOf should not be included. The problem
is how disabled nodes are being parsed here by referenced schema
(snps,dwmac.yaml) and probably is a bug in dtschema package.

Yes, that's what he meant: If a board actually doesn't have Ethernet
configured, dt-validate complains. I saw this before, but didn't find
any solution.
An example is: $ dt-validate ... sun50i-a64-pinephone-1.2.dtb
arch/arm64/boot/dts/allwinner/sun50i-a64-pinephone-1.2.dtb:
  ethernet@1c30000: Unevaluated properties are not allowed ('resets', 'reset-names', 'mdio' were unexpected)
  From schema: Documentation/devicetree/bindings/net/allwinner,sun8i-a83t-emac.yaml

Why exactly is beyond me, but this patch removes this message.

I don't think this should be fixed like this. That's the problem of
dtschema (not ignoring fully disabled nodes) and such patch only moves
from one correct syntax to another correct syntax, which fixes dtschema
problem, but changes nothing here.

Humm, it looks to me like the 'phy-mode' required in snps,dwmac.yaml 
causes the problem, but I can't get a minimized example to fail. 
Something in 'required' shouldn't matter. Definitely seems like an issue 
in the jsonschema package. I'll keep looking at it.

TLDR: A fix in dtschema for this will be in place soon.

I've simplified this down to:
{
    "$schema": "https://json-schema.org/draft/2019-09/schema",

    "unevaluatedProperties": false,
    "allOf":[
        {
            "properties": {
                "foo": true,
                "bar": true
            },
            "required": [ "foo" ]
        }
    ]
}

An instance { "bar": 1 } will fail due to the 'required' failing. When
you have a subschema (what's under 'allOf'), then it all has to pass
to be 'evaluated'. This seems inconsistent to me, but the json-schema
folks say it is operating as intended.

I've got 2 possible fixes. One is to just ignore unevaluatedProperties
errors on disabled nodes like is already done for 'required'. This
means disabled nodes can have any unknown property or child node added
which isn't great. The other way overrides 'required' validation to
always pass on disabled nodes. This would be better, but there are
some exceptions we need to still fail. 'oneOf' with N entries of
'required' to say 1 of N properties must be present for example.
Excluding each one of these cases will be fragile, so probably going
with the first fix.
