Subject: [media] v4l: vsp1: Replace .set_memory() with
VSP1_ENTITY_PARAMS_PARTITION
Author: Laurent Pinchart <laurent.pinchart+rene...@ideasonboard.com>
Date: Mon Sep 12 09:50:13 2016 -0300
The new VSP1_ENTITY_PARAMS_PARTITION configuration parameters type
covers all registers that need to be configured for every partition.
This prepares for support of image partitioning, and replaces the
.set_memory() operation as the memory registers take different values
for every partition.
