    Subject[PATCH v4 2/2] ARM: dts: da850: specify the maximum pixel clock rate for tilcdc
    Date
    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.
