[PATCH 4/6] dts, kbuild: Implement support for dtb vendor subdirs
From: rric@kernel.org (Robert Richter)
Date: 2014-09-05 06:48:59
Also in:
linux-devicetree, linux-kbuild, lkml
Subsystem:
arm and arm64 soc sub-architectures (common parts), kernel build + files below scripts/ (unless maintained elsewhere), open firmware and flattened device tree, the rest · Maintainers:
Arnd Bergmann, Krzysztof Kozlowski, Alexandre Belloni, Linus Walleij, Nathan Chancellor, Nicolas Schier, Rob Herring, Saravana Kannan, Linus Torvalds
From: Robert Richter <redacted> This patch adds support of vendor sub directories for dtb files. Subdirectories can be specified in $(dts-dirs). Kbuild traverses over all directories while building and installing dtb files. The directory tree is also reflected in the install path.
