Rotate RGB display in Yocto BSP6.4

[me_ahani98]

hello dear support
I need to rotate my RGB display 180 degrees in BSP6.4 Yocto referenced image

&panel_dpi {

data-mapping = "bgr666";

status = "okay";

};

How to rotate display 180degree in iMX6ULL

Colibri IMX6 + iris + BSP6.4 upstream + custom device tree overlays and zImage

I wish you the best
