Not sure latest DT team's intention. They usually start from 1, because just before the property comes 'clock-lanes = <0>'.

I'm not sure what the rule is for DSI, but for CSI we number data lanes starting at 1 regardless of whether or not the clock lane is configurable.

How about "This controller support scalable data lanes from 1 to 4. Add the 'data-lanes' property to configure the number of MIPI display panel lanes selected for boards."
