[PATCH v6 6/9] v4l: vsp1: Refactor display list configure operations

Kieran Bingham
2018-02-28T20:52:59Z

The entities provide a single .configure operation which configures the
object into the target display list, based on the vsp1_entity_params
selection.

This restricts us to a single function prototype for both static
configuration (the pre-stream INIT stage) and the dynamic runtime stages
for both each frame - and each partition therein.

Split the configure function into two parts, '.prepare()' and
'.configure()', merging both the VSP1_ENTITY_PARAMS_RUNTIME and
VSP1_ENTITY_PARAMS_PARTITION stages into a single call through the
.configure(). The configuration for individual partitions is handled by
passing the partition number to the configure call, and processing any
runtime stage actions on the first partition only.
