Where do SS lines go after the cbdtu02043?
Also could you please point out the datasheet for the chip.

SBU lines are not connected?

I got your point. I should represent the signal route on dts even though
the driver doesn't use this information.

Yes, please. Bindings / DTS describe the hardware, not the driver's view
on it.
