按照 git 项目上的内容添加的设备树，添加到 sun8i-v3s-licheepi-zero.dts 中，添加的层级有建议吗，因为没修改过设备树，对这块不熟悉，我试了几个地方都不能正常创建设备，下面的内容是否有需要修正的地方

syscon: syscon@1c00000 {
    compatible = "allwinner,sun8i-v3s-system-controller", "allwinner,sun8i-h3-system-control", "syscon";
    reg = <0x01c00000 0xd0>;
    #address-cells = <1>;
    #size-cells = <1>;
    ranges;

    sram_c: sram@1d00000 {
        compatible = "mmio-sram";
        reg = <0x01d00000 0x80000>;
        #address-cells = <1>;
        #size-cells = <1>;
        ranges = <0 0x01d00000 0x80000>;

        ve_sram: sram-section@0 {
            compatible = "allwinner,sun8i-v3s-sram-c", "allwinner,sun4i-a10-sram-c1";
            reg = <0x000000 0x80000>;
        };
    };
};

cedarx: video-codec@1c0e000 {
    compatible = "allwinner,sun8i-v3-cedar";
    reg = <0x01c0e000 0x1000>;
    clocks = <&ccu CLK_BUS_VE>, <&ccu CLK_VE>, <&ccu CLK_DRAM_VE>;
    clock-names = "ahb", "mod", "ram";
    resets = <&ccu RST_BUS_VE>;
    interrupts = <GIC_SPI 58 IRQ_TYPE_LEVEL_HIGH>;
    allwinner,sram = <&ve_sram 1>;
    status = "disabled";
};
       
ion: ion {
    compatible = "allwinner,sunxi-ion";
    status = "disabled";
    heap_cma@0{
        compatible = "allwinner,cma";
        heap-name  = "cma";
        heap-id    = <0x4>;
        heap-base  = <0x0>;
        heap-size  = <0x0>;
        heap-type  = "ion_cma";
    };
};
