[PATCH/RFC,v2,54/56] v4l: vsp1: Store pipeline-related state in pipeline structure

Laurent Pinchart Jan. 22, 2016, 12:57 a.m. UTC
Move the array of BRU inputs and the RPF BRU input index to the pipeline
structure. This prepares the driver for the request API that will need
to handle pipeline state for every request separately from the active
state.
