the linked project uses a MIPI DSI display and not a bridge.This is exactly what i wanted to see!
I wanted to make a hat for the raspberry pi. That would take the DSI from the flex cables and route that to a pi hat that would supply the gpio and I2c for this chip. https://www.ti.com/product/SN65DSI86
What's TI looking to make?
As for reference code, this was the project i was going to use as a reference. https://hackaday.io/project/176098-rasp ... pi-display
There is a driver for DSI86 in the kernel tree since a few years. Just make use of it. You only need to make sure that your design uses a REFCLK (as stated by 6by9 already).
Look at https://www.ti.com/lit/pdf/slla343 and https://www.ti.com/lit/pdf/sllu204 for details.
Keep in mind that you will only be able to make use of DSI86 single channel DSI input (=4-lanes) as the DSI interfaces on the Pi5 are individual peripherals, means you can't connect them for dual channel DSI applications. This will limit the max resolution which you can use the DSI86 with.
Once calculated it if one can achieve 2560x1440 from 4-lane DSI but wasn't convinced to spend money on trying it (and if a CM4 is able to output this resolution).
AFIK the RP1 will not be able to output such high resolutions on single channel (4-lane) DSI --> it would not be possible to drive my 13.3in TFT's.
@6by9: please correct me if my understanding of the RP1 capabilities is wrong.
