Yep, the same IP.

Do you think we should keep the below style?

1)
"rockchip,rk3036-spi", "rockchip,rk3066-spi" for rk3036.
  "rockchip,rk3066-spi" for rk3066.
  "rockchip,rk3188-spi", "rockchip,rk3066-spi" for rk3188.
...

or
2)
  "rockchip,rk3066-spi" for rk3066.
"rockchip,rk3036-spi", "rockchip,rk3066-spi" for rk3036.
  "rockchip,rk3188-spi", "rockchip,rk3066-spi" for rk3188
..

or
3)
"rockchip, rockchip-spi" for rk3036 rk3066.......

Think about the 1) will be googd select.
