Could you use references instead of re-specifying the whole tree
hierarchy in every file a node is used?
Instead of
/ {
pinctrl@11400000 {
};
};
one may simply use
&pinctrl_0 {
};
You might just need to change the location of #include
"exynos3250-pinctrl.dtsi" from top of exynos3250.dtsi to bottom of it.
Oh, well, you also should move all nodes of on-SoC devices under a
simple-bus node called soc. You can see the patch adding dts file for
Exynos5260 for an example [1].
