The panel on this board is a Hannstar HSD100PXN1. The timings we use
are described in imx6qdl-sabresd.dtsi:

        display-timings {
            native-mode = <&timing0>;
            timing0: hsd100pxn1 {
                clock-frequency = <65000000>;
                hactive = <1024>;
                vactive = <768>;
                hback-porch = <220>;
                hfront-porch = <40>;
                vback-porch = <21>;
                vfront-porch = <7>;
                hsync-len = <60>;
                vsync-len = <10>;
            };
