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>; }; _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
