Interfacing (DSI, CSI, I2C, etc.) • Re: Change PLLD frequency to get a specific DSI frequency

Don't forget that running on 3 data lanes is also an option.
not on a Pi4 - which is mentioned in OP's initial post. Maybe that's why he/she is limited to dual-lane DSI only.
But they also mentioned
(with 4-lane I could get 72MHz (3000/42), also out of spec)
which can't be achieved on a Pi4 either. If 4 lanes was being considered, then 3 lanes was also an option.
..
The clock configuration can be altered via the dt-blob.bin file, as documented at https://www.raspberrypi.com/documentati ... figuration. There may be bit-rot in there as this hasn't been touched for many years.
Would this be applicable to RP1 on a Pi5 (or later products which will/may use RP1) as well?
No, dt-blob.bin isn't a thing at all on Pi5.
RP1 DSI blocks each have their own PLLs, so should be able to produce the link frequencies requested.
