I made a commit of my branch of CircuitPython here with the ESP32-S3 LCD peripheral updates:

https://github.com/kmatch98/esp-idf/tree/release/v4.4_rgblcd

this also depends upon some updates to the ESP-IDF for driving the LCD peripheral:

https://github.com/kmatch98/circuitpython/tree/esp32s3_dotclockdisplay

These ESP-IDF changes are required to allow CircuitPython to allocate the FrameBuffer, to prevent the LCD peripheral from getting starved for data during DMA transfers, and allows CircuitPython to trigger the screen refreshes, thus preventing “tearing”.
