How do you envision a four-lane sensor being described?
data-lanes = <0 1 3 4>;
clock-lanes = <2>;
?
The binding document for video-interfaces.txt says:
- clock-lanes: an array of physical clock lane indexes. Position of an entry
determines the logical lane number, while the value of an entry indicates
physical lane, e.g. for a MIPI CSI-2 bus we could have "clock-lanes = <0>;",
which places the clock lane on hardware lane 0. This property is valid for
serial busses only (e.g. MIPI CSI-2). Note that for the MIPI CSI-2 bus this
array contains only one entry.
So I think you need to have a good reason to make the clock lane non-zero.
