Hello

I fail to do this.
I do the following (keeped only clock stuff)
properties:

clocks:
items:
- description: Bus clock
- description: Module clock
- description: MBus clock

clock-names:
items:
- const: ahb
- const: mod
- const: mbus

if:
properties:
compatible:
items:
const: allwinner,sun50i-h6-crypto
then:
properties:
clocks:
minItems: 3
maxItems: 3
clock-names:
minItems: 3
maxItems: 3
else:
properties:
clocks:
minItems: 2
maxItems: 2
clock-names:
minItems: 2
maxItems: 2

With this, the dtb_check keep complain that a64 have two short clocks.
