About the linx dts(device tree) include files?

I come across a problem as follows:

there is a origin dts or dtsi files in the linux kernel dir: 

 arch/arm64/boot/dts/

Assume that there is a file : B.dtsi

I want to create a A file in that direction:

now arch/arm64/boot/dts/A/

i want to create dts file C.dts in A dir,then it include the file coming from dts/xx.dtsi

i can use the absolute dir path in file C.dts

include "arch/arm64/boot/dts/B.dtsi"

But is there a -i option like C compile ,the dtc tool can search the include file automatic after i set the compile option?

There is -i option when compiling dtb

use:

DTC_FLAGS ?= -i $(DCT_EXTRA_PATH)

then you should use:

#include <B.dtsi>

or 

/include/ "B.dtsi"

in your dtsi files
