Subject: [PATCH v3 4/6] xen/device-tree: Make dt_match_node match props
Date: Wed, 7 Sep 2016 08:56:15 +0200 [thread overview]
Message-ID: <1473231377-7800-5-git-send-email-edgar.iglesias@gmail.com> (raw)
In-Reply-To: <1473231377-7800-1-git-send-email-edgar.iglesias@gmail.com>
From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>
Make dt_match_node match for existing properties.
We only search for the existence of the properties, not
for specific values.
