[yocto] Yocto SDK: how to rebuild *.dtb? (fatal error: dt-bindings/gpio/gpio.h: No such file or directory)

[Jerry Lian]

I installed yocto SDK for my beaglebone black.
But when I try to rebuild am335x-boneblack.dtb, I got error:

"arch/arm/boot/dts/am33xx.dtsi:11:10: fatal error:
dt-bindings/gpio/gpio.h: No such file or directory"

Any hint? Thanks!

Jerry
