Module for ili9488

[namezys]

I have 3.5TFTBIGTREETECHTFT35 SPI V2.1` that is used for 3D printers with custom linux module.

After some investigation we found that:

• This TFT is based on ILI94888
• There is custom Linux kernel that works with this TFT.
• Custom driver is used with strange name
• DST is patched

Therefore we have valid custom module for fbtft so it's possible to port to new DRM.

I have:

• this TFT screen
• orange pi 3 with klipper

Unfortunately, I built custom kernel about 20 years ago. I'm not sure how I can do it on Armbian.
BTW I can try to port this driver but I don't know when.

Check if your kernel have the driver module:
