as said in a previous mail, please adapt this to use clock-names for the
two clock variant. Maybe something like

clocks:
  minItems: 1
  maxItems: 2

clock-names:
  minItems: 1
  maxItems: 2
  items:
    - const: apb_pclk
    - const: debounce

if:
   properties:
     clocks:
       items:
         const: 2
then:
   required:
    - clock-names

[not yet sure if that works]

While this is fine, the version above with descriptions is better.

Don't need maxItems here. Implied by 'items' length.

This says clocks must have values of 2. You want this:

clocks:
  minItems: 2

Note that is condition will also be true if 'clocks' is not present. I
assume it's required elsewhere.
