This isn't consistent with "[PATCH v3 09/11] PCI: layerscape: Add EP mode..."
as that patch drops the fallback "fsl,ls-pcie-ep". Either the fallback must
be preserved in the driver, or you need to drop it here.

What if there are existing users that depend on the fallback?

(I'm also not sure if that comma should have been dropped).

Thanks,

Andrew Murray
