Since we have "reg-names" already, we don't really need any 
description, so you could just have:

reg:
  minItems: 3
  maxItems: 4

> +          - const: sram

You could just add "tcsm" to the items list, and add:
minItems: 3
maxItems: 4

Same as above, since we already have clock-names, the descriptions 
don't bring much.

You can replace with:

clocks:
  minItems: 1
  maxItems: 2

I think you could just add:
minItems: 1
