Hi, I am currently trying to use vc4-kms-dsi-generic-overlay.dts with following 1080p@60fps settings to output DSI signal:
What DSI Output Clock from Pi 5 should I expect from these settings? Is it going to be the same as 148500000 that I configured? I received these logs: May I know where can I find the code that RP1 is being configured with the DSI clock to output?
I have a DSI Rx that is measuring DSI clock at 873848800 which I am not sure if it is measuring the correct thing or not?

Thanks.
