[PATCH v2 31/54] v4l: vsp1: Store active selection rectangles in a pad config structure

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

 



Use the pad config structure part of the vsp1_entity to store all active
pad selection rectangles. This generalizes the code to operate on pad
config structures.
