Subject: [PATCH/RFC] kbuild: Create a rule for building device tree overlay objects
Date: Tue, 12 May 2015 13:56:56 +0200
Message-ID: <1431431816-24612-1-git-send-email-geert+renesas@glider.be>
Return-path: <linux-kernel-owner@vger.kernel.org>
Sender: linux-kernel-owner@vger.kernel.org

Cc: linux-kbuild@vger.kernel.org, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org, Geert Uytterhoeven <geert+renesas@glider.be>

This allows to handle device tree overlays like plain device trees.

Questions:
  - Do we want dtso files under arch/<arch>/boot/dts/, too?
  - Do we want to move the dts files outside the kernel repository
    first?
