全志v3s，荔枝派主线 linux 5.2，用的 https://github.com/aodzip/cedar 硬编驱动，编译构建都没有问题，但是启动后 /dev 下没有 cedar_dev 和 ion，启动日志中也没有关于 codec 相关的日志，有大神遇到类似问题吗，或者如何排查，怎么打出来初始化相关的日志
还有个情况，cedar 如果按 模块 编译就会报错，主要是编译器版本高导致的语法检查报错，如何直接编译进内核，就没报错

设备树加了吗

设备树加了吗
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";
