==Peripheral LVDS ==
Here below an example of device tree configuration used on standard DAVE's kit for the AXELLite SOM:
From the ''carrier board device tree'' where two LVDS channel have been configured for a dual LVDS panel (1280x800 24bit and two 800x480 18bit):
<pre>

status = "okay";  lvds-channel@0 { fsl,data-mapping = "spwg"; fsl,data-width = <18>; crtc = "ipu2-di0"; status = "okay"; primary;

lvds-channel@1 { fsl,data-mapping = "spwg"; fsl,data-width = <18>; crtc = "ipu1ipu2-di1"; status = "okay";
display-timings { native-mode = <&timing1>; timing1: AM800480STMQW_TA1 am_800480stmqw_ta1 { clock-frequency = <33260000>; hactive = <800>; vactive = <480>; hback-porch = <128>; hfront-porch = <128>; vback-porch = <15>; vfront-porch = <30>; hsync-len = <10>; vsync-len = <2>; }; }; };
