Subject: [PATCH] dt-bindings: iio: samsung,exynos-adc: add common clock properties

Add common properties appearing in DTSes (assigned-clocks and similar)
to fix dtbs_check warnings like:

arch/arm/boot/dts/exynos3250-artik5-eval.dt.yaml:
adc@126c0000: assigned-clock-rates: [[6000000]] is not of type 'object'
arch/arm/boot/dts/exynos3250-artik5-eval.dt.yaml:
adc@126c0000: assigned-clocks: [[7, 238]] is not of type 'object'

Does it mean that assigned-clocks related properties have to be added to
almost all bindings? IMHO this is an over-engineering and this has to be
handled somewhere else...

To my understanding: yes, and we already added it to multiple schemas.

Would have to be made a part of the core schema (just like pinctrl nodes
etc).

That's the case now. It's contingent on having a 'clocks' property in
the node.

Do I understand correctly: with new dtschema my patch is not needed anymore?
