Interfacing (DSI, CSI, I2C, etc.) • Re: Learning MIPI DSI on PI 5

it's not the overlay which sends DSI commands, It's the driver - if needed.

for the LCDs which do not require an init (and/or power on) sequence you can use the dsi_gerneric overlay https://github.com/raspberrypi/linux/bl ... verlay.dts

a custom overlay will call a kernel driver ...

Thanks for the clarification. Now i understand DT overlays calls for drivers listed under the compatible line in the overlay.

Im a noob at the linux side. Slowly trying to get some bearings about how these work.

1. Since the driver is the one that sends the DSI commands, how to adapt the driver to send custom commands?

I see Nexus 7 2nd gen 1200x1920 lcd runs with pi compute module with some overlays. That JDI lcd is command mode lcd, how did they
implement the commands in the driver?
