Hi Philipp,

What are this panel timings? The adjustment should increase the vertical
back porch by up to two lines (so it is at least two lines), reducing
the front porch or vsync length by the same amount. Does this panel use
the HSYNC/VSYNC signals embedded in the LVDS stream?

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>;
            };
