I would like to get an idea of what's needed to implement a RGB interface for the LCD_CAM module, i was told by @Dominaezzz that the DMA api's aren't currently powerful enough to support RGB mode. For context i'm attempting to use a qualia esp32s3 board from adafruit that uses a RGB TTL connector

Long story short, all the options available in https://docs.espressif.com/projects/esp-idf/en/release-v5.3/esp32s3/api-reference/peripherals/lcd/rgb_lcd.html should be supported by the hal. Either by having the implementation here or providing APIs for users to DIY it. (I much prefer the latter).

We also need one of the maintainers to have a devkit that can run an example with it, like ESP32-S3-LCD-EV-Board.

Any of these kits also work (in order of preference, the Elecrow ones are annoying to iterate on).

Now that #2242 (with the DMA buffer view feature) has landed, I can submit a PR for this.
All the (non PSRAM related) features needed for a decent no_std version of esp_lcd can now be implemented outside of esp-hal.
The XIP from PSRAM feature is still an important piece of the puzzle but that doesn't have to block the initial driver.
