In FSD we have two instances of EQoS IP, one in PERIC block, which requires total 10 clocks  to be configured and another instance exist in FSYS0 block which needs 5 clocks to be configured, so we kept minItems as 5 and maxItems as 10, but looks like latest items schema do not need maxItems entry so we will drop maxItems entry. In my understanding minItems still required so it should be kept with minimum number of clock requirements.

No, the code is fine then.

Remember about vendor prefixes for every custom property.
