Describe the enhancement

I recently managed to get the aforementioned MIPI DSI display working when attached to an esp32-p4-dev-kit using the esp-idf framework. However, for my project I would very much prefer to draw on this screen using esphome (for ease of use and communication with Home Assistant).

https://components.espressif.com/components/waveshare/esp_lcd_dsi/versions/1.0.7/ contains a lot of the information required for the CUSTOM model of the mipi_dsi platform, but I haven't managed to get anything working with esphome so far.

Use cases

ah, everything you could do with any screen. :-)

in my particular case I'd like to use the display to build into a nightstand-device to interact with Home Assistant.

Anything else?

thank you SO much for your contributions in this field, @clydebarrow
