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

as your overlay does not include any details on touch I will ignore that portion. Example DT uses i2c_csi_dsi for I2C interface (I2C-10 on CM4).
Haven't you been told that it's using I2C-10?

Change below line to the I2C interface of your dreams. NOTE: don't ask me on any issues related to I2C addresses as I ned to assume you know what you're doing. If not, read the linked threat as it gives you tons of explanations and examples how to deal with this bridge driver.

Code:

        target = <&i2c_csi_dsi>;

Code:

dtoverlay=vc4-kms-dsi-ti-sn65dsi83-10inch-overlay
seriously?

Code:

start_x=0
what do you need that for?

Code:

gpu_mem_256=128gpu_mem_512=256gpu_mem_1024=256
Are you on Bookworm? Why do you assign additional memory to the GPU?

Code:

dtparam=i2c_vc=on
Used for what?

Code:

dtoverlay=i2c-rtc,ds1307,i2c1
Your RTC is on the same bus as the bridge?

Code:

lcd_ignore=1
Get rid of that.
