That's seem the incorrect string to match the spi driver.
Will it break the backward compatibility for some dtb if not
falling back to "rockchip,rockchip-spi" ?
The rk3036 shouldn't work if you read the driver/spi/spi-rockchip.c.
since the "rockchip,rockchip-spi" is *not* exist in linux kernel.
..
static const struct of_device_id rockchip_spi_dt_match[] = {
{ .compatible = "rockchip,rk3066-spi", },
{ .compatible = "rockchip,rk3188-spi", },
{ .compatible = "rockchip,rk3288-spi", },
{ .compatible = "rockchip,rk3399-spi", },
{ },
}
