[PATCH] kbuild: Allow using host dtc instead of kernel's copy
From: Rob Herring <robh@kernel.org>
Date: 2016-02-11 22:34:39
Also in:
linux-kbuild
Subsystem:
kernel build + files below scripts/ (unless maintained elsewhere), the rest · Maintainers:
Nathan Chancellor, Nicolas Schier, Linus Torvalds
Development of dtc happens in its own upstream repository, but testing dtc changes against the kernel tree is useful. Change dtc to a variable that users can override.
