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@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.
