Interfacing (DSI, CSI, I2C, etc.) • Re: CM4 DSI1 + SN65DSI83 Bridge based display (6.1.x kernel)

Haven't you been told that it's using I2C-10?

GPI0/1 LCD SDA/SCL in my first post

I know that you're using I2C-0.
I've told you that I'm using I2C-10 in my overlay.
I've shown you which line you need to change.

So question: how do you need to change the line below to have the bridge connected to I2C-0Some hints:
Normally on a Pi4 you have the I2C busses stated below:
- i2c-1 on GPIOs 2&3. Requires dtparam=i2c_arm in config.txt
- i2c-20 and i2c-21 on the HDMI ports for reading the EDID. Requires dtoverlay=vc4-kms-v3d in config.txt.
- i2c-0 on GPIOs 0&1. Requires dtparam=i2c_vc in config.txt.
- i2c-10 for the camera and display. Requires dtparam=i2c_vc in config.txt.
- i2c-22 as the parent hardware block for i2c-0 and i2c-10, as they are just alternate pinmuxing options for the one block.
