Which platform does the schema currently match? None, because the
Marvell ones get these:

     28  crypto@800000: interrupt-names:5: 'mem' was expected
     28  crypto@800000: interrupt-names:4: 'eip' was expected
     28  crypto@800000: interrupt-names:3: 'ring3' was expected
     28  crypto@800000: interrupt-names:2: 'ring2' was expected
     28  crypto@800000: interrupt-names:1: 'ring1' was expected
     28  crypto@800000: interrupt-names:0: 'ring0' was expected
     28  crypto@800000: 'dma-coherent' does not match any of the
regexes: 'pinctrl-[0-9]+'

(28 is the number of occurrences)

The existing list of names defines the order AND index. Since there
are 2 versions already in use, you have to define 2 lists.

Not a documented tag. Don't make-up your own ones.
