Subject: [PATCH v2 2/2] ARM: dts: da850-lcdk: specify the maximum pixel clock rate for tilcdc
Date: Mon, 28 Nov 2016 13:15:28 +0100 [thread overview]
Message-ID: <1480335328-4010-3-git-send-email-bgolaszewski@baylibre.com> (raw)
In-Reply-To: <1480335328-4010-1-git-send-email-bgolaszewski@baylibre.com>
Due to memory throughput constraints any display mode for which the
pixel clock rate exceeds the recommended value of 37500 KHz must be
filtered out.
Specify the max-pixelclock property for the display node for
da850-lcdk.
