Subject: [PATCH v2 1/2] ARM: dts: da850-lcdk: add the dumb-vga-dac node
Date: Mon, 28 Nov 2016 13:15:27 +0100	[thread overview]
Message-ID: <1480335328-4010-2-git-send-email-bgolaszewski@baylibre.com> (raw)
In-Reply-To: <1480335328-4010-1-git-send-email-bgolaszewski@baylibre.com>

Add the dumb-vga-dac node to the board DT together with corresponding
ports and vga connector. This allows to retrieve the edid info from
the display automatically.
