linux编译,dts设备树出错
arch/arm64/boot/dts/: fatal error: dt-bindings/pwm/pwm.h: No such file or directory
#include <dt-bindings/pwm/pwm.h>

compilation terminated.
其实这个pwm.h文件是存在的，只是解压内核时软链接丢失了
可以重建软链接即可

RK3399的软链接：scripts/dtc/include-prefixes/dt-bindings

S5P4418/S5P6818的软链接:arch/arm/boot/dts/include/dt-bindings
