Hi, Guennadi
The solution you said is right. We could use parameters to
distinguish different power managerment, gain, etc.
So ov5642_default_regs_init and ov5642_default_regs_finalise in the
patch could be removed in the final version, right?
Since it's not common for all boards. What I think about is that
ov5642.c is a common driver, which could use on almost
all platforms. But the setting could be different from different
boards from my experience on three boards. And the setting
contains lots of registers. OV5642 document should be learnt a lot
before merging the patch.
Thank you
Angela
