Only 3 wires? Many of these SPI displays need the D/C line as well to switch between data and command, but potentially switching to 9 bit SPI transfers deals with it.
The easiest approach if you have an initialisation sequence is to look at the mipi-dbi driver, and create a firmware file for your new panel. https://github.com/notro/panel-mipi-dbi/wiki
I don't have any issues on initialisation, I need suppport on sending display data through SPI to ILI9242c, can you how to send that, How to switch from command to Data.
By using the D/C pin. That's why this type of interface is then referred to as 4-pin SPI.

I give a f* on the display controller data sheet! Thanks for sharing but I have that/know what's inside.

I've requested you to share the Display data sheet. Anyhow, good luck with your display as I'm done here.
