Interfacing (DSI, CSI, I2C, etc.) • MIPI rpi display

Hi there,

I have been sorting out a custom touch screen for a car, its a generic non custom 8 inch lcd however the manufacturer has provided a custom touch cover for my use. I just wanted to see if anyone could offer any advice on interfacing with the pi as I want to drive this directly from my rpi. Its a 1280x800 ips panel with a ili9881c driving it. I will attatch the 32 pin mipi pinout for ref, i am aware the backlight may require seperate power that the rpi cant provide

kind regards and TIA, any help is much appreciated.
