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>;
};
