I'm a little confuse, I have upstreamed rockchip-i2s, and the i2s driver 
set the compatible like:
- compatible: should be one of the followings
    - "rockchip,rk3066-i2s": for rk3066
    - "rockchip,rk3188-i2s", "rockchip,rk3066-i2s": for rk3188
    - "rockchip,rk3288-i2s", "rockchip,rk3066-i2s": for rk3288
    - "rockchip,rk3399-i2s", "rockchip,rk3066-i2s": for rk3399
and the driver only has
static const struct of_device_id rockchip_i2s_match[] = {
	{ .compatible = "rockchip,rk3066-i2s", },
	{},
};

The spi of rk3399 as same as rk3066, rk3188, rk3288, like i2s, if they 
are keep different rules ?
