基于飞凌的开发板设计，这里需要使用到RK3568的串口，开发板只开放了UART2、UART3、UART4、UART5、UART8。查看文档，准备配置UART0、UART6、UART7、UART9。一共9个串口使用。剩下的一个串口被网口1占用，暂时不修改。
修改设备树DTS文件配置。

/home/forlinx/3568/OK3568-linux-source/kernel/arch/arm64/boot/dts/rockchip
rk3568.dtsi为基本配置文件，只需要修改OK3568-C-common.dtsi。
占用了LVDS的管脚，LVDS无法使用。文章来源：https://www.toymoban.com/news/detail-546726.html
