Subject: [PATCH v6 1/4] ARM: dts: tegra: Remove usage of deprecated skeleton.dtsi
Date:   Wed, 23 May 2018 11:56:43 +0200
Message-Id: <1527069406-6359-1-git-send-email-krzk@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Remove the usage of skeleton.dtsi because it was deprecated since commit
9c0da3cc61f1 ("ARM: dts: explicitly mark skeleton.dtsi as deprecated").
It also allows later to fix DTC warnings for missing unit name in
/memory nodes.

The /chosen and /aliases nodes are added only when dependent DTSes do
not define them.  Compiled DTB is the same as before this commit.

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

---

Changes since v5:
1. New patch, split with skeleton.dtsi removal (suggested by Stefan).
