citing Mark Rutland (one of the dt maintainers):

--
  That's why I said in addition to the common one. I'd only expect the
  driver to look for "rockchip,rk3066-spi", but a DTB could have:

        compatible = "rockchip,rk3188-spi", "rockchip,rk3066-spi";

  Seeding the DTBs with the extra strings early makes it more likely that
  we can rely on them later. If we don't happen to need them they only
  clutter some DTBs.

so it looks like the driver is doing the right thing right now
