Commit Message

Rob Herring (Arm) June 15, 2021, 7:15 p.m. UTC 
If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

This condition is partially checked with the meta-schema already, but
only if both 'minItems' and 'maxItems' are equal to the 'items' length.
An improved meta-schema is pending.

For this one, the fact it overrides maxItems elsewhere makes this a little
bit odd.  I guess we can get used to it being implicit.

Does this enforce the maxItems to be 2 only now? Or should this be dropping the
minItems here which matches the length of items instead of maxItems?

I have originally listed the individual item list only for the mandatory items
and rest are scalable. I provided this through "additionalItems: true" under
this property.

Also, have the exact same usage in
Documentation/devicetree/bindings/remoteproc/ti,k3-r5f-rproc.yaml as well which
is not included in this patch.

Good catch. This should be dropped. The meta-schema doesn't enforce
this if "additionalItems: true" which is rarely used.

Yeah, I just missed this one. I've double checked and there aren't any more.

While resolving the conflict with commit fea99822914039c6
("dt-bindings: net: document ptp_ref clk in dwmac") in soc/for-next,
I noticed the following construct for clock-names:

  clock-names:
    minItems: 3
    maxItems: 6
    contains:
      enum:
        - stmmaceth
        - mac-clk-tx
        - mac-clk-rx
        - ethstp
        - eth-ck
        - ptp_ref

Should this use items instead of enum, and drop maxItems, or is this
a valid construct to support specifying the clocks in random order?
If the latter, it does mean that the order of clock-names may not
match the order of the clock descriptions.

Gr{oetje,eeting}s,

                        Geert

'contains' is true if one or more entries match the strings. So it is
really saying one of these is required. That's not really much of a
constraint. There's 'minContains' and 'maxContains' in newer
json-schema versions (not yet supported) that could add some
constraints if there has to be at least N entries from contains. An
'items' schema (as opposed to a list) would say all items have to
match one of the strings. I'm sure that's too strict.

TLDR: clocks for this binding are a mess and the above is probably all
we can do here.
