Custom DTS for elecrow 7.0inch board

[Stimaleger]

Hello guys,
I'm trying to make a custom project based on this board : https://www.elecrow.com/wiki/esp32-display-702727-intelligent-touch-screen-wi-fi26ble-800480-hmi-display.html using zephyr rtos.

I'm quite new to Zephyr RTOS and currently trying to write a custom Device Tree Source (DTS) file for this board, particularly for the display interface.
The board uses EK9716BD3 and EK73002ACGB display drivers. These seem to be compatible with a MIPI-DBI bit-bang interface with panel-timing, but I'm not entirely sure how to describe this using DTS syntax. Unfortunately, I couldn't find any examples for this type of device.
Any guidance or examples would be greatly appreciated!
Thank you in advance!

I think the board itself was designed to utilize the ESP32-S3's LCD Controller, which does not seem to be supported in Zephyr yet.

For a hint regarding your question, you can refer to zephyr,mipi-dbi-bitbang dts binding and the mipi_dbi_bitbang.c, which mainly focus on describing GPIO pins.

I came to the same conclusions, so I started developing the associated driver. We'll see where it takes me. Thanks for your response!
