配置步骤：

  1. 修改 /home/zgk/openwrt-ssd20x/18.06/build_dir/target-arm-linux-gnueabihf_glibc/linux-sstar_ssd20x/linux-4.9.84/arch/arm/boot/dts/WT2015.dtsi image disable改为ok image
  2. 在18.06下make menuconfig,做如下配置: image

结果在/dev/下没有出现spidev0.0，请问有什么步骤漏掉了或者配置错了吗？

参考最新的代码，已经添加spidev，使用GPIO4-GPIO7。 重新编译WT2015，不用改配置。

GPIO2-3： I2C1 GPIO8-11： SPI GPIO6-7：I2C0 GPIO4: PWM0 GPIO5: PWM1 默认已配置好（WT2015），请重新编译WT2015
