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>; };
