重现步骤
就是在加庐山派的3.1寸屏幕的触摸驱动的时候，不知道为什么，明明i2c那些都配置好了，但就是搜不到，很奇怪
期待结果和实际结果
软硬件版本信息
linux+rt-smart系统，版本为k230_canmv_lckfb_defconfig v1.9
错误日志
尝试解决过程
补充材料

src/little/linux/arch/riscv/boot/dts/kendryte/k230_canmv_lckfb.dts 里面增加类似 如下代码试下
i2c3 = &i2c3;
aliases {
serial3 = &uart3;
mmc0 = &mmc_sd0;
mmc1 = &mmc_sd1;
i2c0 = &i2c4;
i2c1 = &i2c3;
};
i2c3的初始化是好了，但是还是没法解析scl-gpio这是为什么，i2c数据不能正常写
