-
First test the binding :
make clean && make -j8 dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/<path to yaml>
-
Then check the
dtsi/dts
files that are compatible with this schema. Example :rg "generic-uhci"
, here rg is recursive grep program
arch/arm/boot/dts/aspeed/aspeed-g4.dtsi
158: compatible = "aspeed,ast2400-uhci", "generic-uhci";
arch/arm/boot/dts/aspeed/aspeed-g5.dtsi
186: compatible = "aspeed,ast2500-uhci", "generic-uhci";
-
Now set options to cross-compile with the architecture that has the dts files (here-arm) :
export CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm KBUILD_OUTPUT=out/
-
Now make config file :
- First clean your setup (and you have to build your bindings again in step 4)
- Then you may have to run
make mrproper
to switch to the new architecture - Then run
make defconfig
for default config - Build the bindings again :
make -j8 dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/<path to yaml>
-
Now test the dts files :
make -j8 dtbs_check DT_SCHEMA_FILES=<path to yaml>
