[PATCH 10/57] media: atomisp: Remove V4L2_CID_BIN_FACTOR_HORZ/_VERT

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The bin-factor-x and bin-factor-y ctrls are only used internally to
get a single value to pass to atomisp_css_input_set_binning_factor(),
which is supposed to tune the lens-shading correction for the binning
factor. But all sensor drivers return either 0 or 1 for this,
with 0 meaning unset and 1 meaning no-binning. Even though some modes
do actually do binning ...

Also note that the removed atomisp_get_sensor_bin_factor() would fall
back to 0 if either the x and y factor differ or if the ctrls are not
implemented (not all sensor drivers implement them).

Simply always pass 0 to atomisp_css_input_set_binning_factor().

This is part of a patch-series which tries to remove atomisp specific /
custom code from the sensor drivers, with as end goal to make the atomisp
drivers regular camera sensor drivers.
