What the driver is not relevant. Please define all possible 
configurations. Or just omit? What's the behavior if omitted?

I wrote this as to document the hardware (there is no datasheet around and
I fear that findings will be forgotten one day)... but if you say it's
not relevant...
...well, then I can as well just write it in my local notes and remove the info
from here.

Also, I'm sorry for the *very* late reply. I've been busy quite a lot
in these days!
By the way, I'll push a v3 for this one ASAP!

The frequency needs to come from DT; it's not a property of the sensor.

I think we've used to specify the number of lanes if it's configurable,
instead of having defaults. I'd do the same here, i.e. require data-lanes.

You said this is an 8 MP sensor,

- but 5948H x 4140V is more than 8 MP.

+
+description: |-
+  The Sony IMX300 is a 1/2.3-inch Stacked CMOS (Exmor-RS) digital image
+  sensor with a pixel size of 1.08um and an active array size of
+  5948H x 4140V. It is programmable through I2C interface at address 0x10.
+  Image data is sent through MIPI CSI-2, which is configured as either 2 or
+  4 data lanes.
