Please replace these with names macros where possible. I'm sure quite a
few of the registers configured here are documented in the datasheet.
The registers that configure the mode (analog crop, digital crop,
binning, skipping, ...) should be computed dynamically from the subdev
pad format and selection rectangles, not hardcoded.
I agree, but we get the sensor settings based on our requirements from
the vendor, i will check if we can get some more info regarding the
crop, binning, skipping etc...
Some of this infomation should be available in the datasheet. Use at
least the register names that can be found, for those that can't there's
not much that could be done.
Sorry to say that I don't have the details in this case. We have
previously reached out to the sensor vendor, but they are not willing to
disclose any of these details. We hope for your understanding of the
constraints we're facing and truly value your support.
Thanks,
Pratap
