a5c7592366af introduced this interrupt and interrupt-names block. Later, 53c6d854be4e9 added ipq5332 to this section. Since a5c7592366af introduced the maxItems and I wanted to include minItems also (to accomodate ipq5332) I used a5c7592366af in the fixes tag. Will 53c6d854be4e9 be a more appropriate choice?

Yes. Will have a separate block for ipq5332. Went with min/max based
on one of the previous blocks that had min/max as two and three for
a group of SoCs.
