ipa: rkisp1: lsc: Resample polynomial lens shading tables at configure time The lens shading correction is always applied based on the sensor crop bounds. This leads to incorrect lens shading correction for analog crops that do not cover the whole sensor. To fix that, we need to adapt the lens shading table for the se…
