RK3568未找到ttysWK设备节点

Chip Platform Rockchip
1

固件类型：自行编译的固件
SDK包名称：rk356x_linux_release_20211019
SDK修改内容：DTS使能spi1和spi_wk2xxx
Log日志：log.zip

在使能相应设备节点后，烧录内核镜像，在/dev中找不到ttysWK*
执行dmesg | grep wk 的日志如下：

若最新的5.10版本固件，使能spi1和spi_wk2xxx 后，仍无法找到/dev/ttysWK，但是内核打印信息不同：

root@firefly:/home/firefly# dmesg|grep wk
[    5.944042] wk2xxx_init: SPI driver for spi to Uart chip WK2XXX, etc.
[    5.944058] wk2xxx_init: V2.4 On 2022.07.24
