Subject: [PATCH 2/3] ARM: dts: da850: specify the maximum bandwidth for tilcdc
Date: Fri, 25 Nov 2016 17:03:14 +0100 [thread overview]
Message-ID: <1480089795-29811-3-git-send-email-bgolaszewski@baylibre.com> (raw)
In-Reply-To: <1480089795-29811-1-git-send-email-bgolaszewski@baylibre.com>
It has been determined that the maximum resolution supported correctly
by tilcdc rev1 on da850 SoCs is 800x600 at 60. Due to memory throughput
constraints we must filter out higher modes.
Specify the max-bandwidth property for the display node for
da850-based boards.
