tried many ways of defining it, but none passes with the examples. either to short (first example) or too long (second)

as far as i understand the logic it should be similar to this:

properties:
  compatible:
    oneOf:
      - items:
        - enum:
          - marvell,berlin2q-achi
        - const: generic-ahci
      - items:
        - enum:
          - brcm,iproc-ahci
          - cavium,octeon-7130-ahci
          - hisilicon,hisi-ahci
          - ibm,476gtr-ahci
          - marvell,armada-3700-ahci
          - marvell,armada-380-ahci
          - snps,dwc-ahci
          - snps,spear-ahci

this passes the dt-binding_check (examples) for me, but i guess there are many more compatibles defined with the generic.

dtbs_check found some more like

'brcm,iproc-ahci'
'marvell,armada-8k-ahci'
and many more

it looks like these are also checked in the enum, so the yaml itself look correct, but needs some kind of wildcard instead of the "marvell,berlin2q-achi" as second for the generic-ahci compatible
