Subject: [PATCH 1/3] dt-bindings: arm: samsung: Force clkoutN names to be unique in PMU

The clkoutN names of clocks must be unique because they represent
unique inputs of clock multiplexer.

You shouldn't need the 'allOf', just add uniqueItems at the same level as items.

If you mean something like:
56 uniqueItems: true
57 items:
58 pattern: '^clkout([0-9]|[12][0-9]|3[0-1])$'

Then the dt_binding_check fails:

dev/linux/Documentation/devicetree/bindings/arm/samsung/pmu.yaml: properties:clock-names:
'uniqueItems' is not one of ['$ref', 'additionalItems', 'additionalProperties', 'allOf', 'anyOf', 'const', 'contains', 'default', 'dependencies', 'deprecated', 'description', 'else', 'enum', 'items', 'if', 'minItems', 'minimum', 'maxItems', 'maximum', 'not', 'oneOf', 'pattern', 'patternProperties', 'properties', 'required', 'then', 'type', 'typeSize', 'unevaluatedProperties']

I can add it.

The other option is to fix this in the clock schema. I'm not sure if
there's a need for duplicate clock-names. Seems unlikely. I'll test
that.

Actually, clock-names is already set to be unique. Did you see otherwise?

Yeah, I duplicated on purpose "clkout1" and it was not reported as an
error. That's why I added "uniqueItems".

Are you running using DT_SCHEMA_FILES? If so, you won't get the core schema.

Ah, yes, now I see proper errors. Thanks for pointing this.

I'll send next version of this patch only (if others are ok).

Of course, there will be no v2, this patch can be just skipped.

Kind of redundant to list this here.

You can add a description with the item:

items:
- pattern: '^clk_uart_baud[0-3]$'
description: N = 0 is allowed for SoCs without internal baud clock mux.

Or leave it here is fine too.

You can drop this.

You only need the last case. With 'minItems: 2', the additional items
here will just be ignored.

Similar simplification can be done here.

Drop this. It will cause a warning if we enforce 'aliases' to be at the
root node.

This caused error:

I applied rest of comments. Thanks for review!
