It's not a round display until we get a Stargate going

Adafruit Industries

When you see a round display, do you think... pizza? planet? beachball? no? how about a Stargate animation! there's three parts to getting these funky displays working with raspberry pi over the DSI port: the SPI configuration of the screen, the I2C configuration of the ICN6211 converter and the DTO device tree overlay on the pi itself. all must be perfect for an image to appear! to make it less complex, we're going to only do one part at a time and celebrate the successes. we got the SPI config working with blinking the display on and off, and the ICN config was proven when we displayed a colorbar test pattern. finally we load a DTO up which will tell the pi to look for a 720x720 display off the dsi0 port (https://github.com/timonsku/display-overlays/blob/main/panels/HD40015C40/HD40015C40.dts) and voila! a 60Hz display with full color... we can even play any video off the desktop with VLC and it looks great.
