Subject: [PATCH] ARM: dts: da850: enable the memctrl and mstpri nodes per board
Date: Thu, 24 Nov 2016 10:31:24 +0100
Message-Id: <1479979884-9624-1-git-send-email-bgolaszewski@baylibre.com>
Sender: linux-kernel-owner@vger.kernel.org
Content-Length: 1408
Lines: 50

Currently the memory controller and master priorities drivers are
enabled in da850.dtsi. For boards for which there are no settings
defined, this makes these drivers emit error messages.

Disable the nodes in da850.dtsi and only enable them for da850-lcdk -
the only board that currently needs them.
