By the way, I just looked at the in tree ov5642 driver, and there is
no {0x3042, 0xf0} sequence, so I must
be mistaken.
However, there are certainly some common bit and pieces, but the devil
hides in the details.
Some register with the same adress and the same name in the documentation
can have different effects from one sensor to another, so I don't
believe in one firmware file to rule them all.
However, the register reading / writing functions are duplicated
across several omnivision driver.
