From 7c93931e4cee25315173ec40b8a52a02d070f852 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Tue, 13 Dec 2016 11:09:19 +0100 Subject: ARM: dts: da850: specify the maximum pixel clock rate for tilcdc At maximum CPU frequency of 300 MHz the maximum pixel clock frequency is 37.5 MHz[1]. We must filter out any mode for which the calculated pixel clock rate would exceed this value. Specify the max-pixelclock property for the display node for da850-lcdk.
