From d21fbbb4e9705189cabd724de0dec3f01fb362d1 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sun, 11 Sep 2016 19:39:30 -0300 Subject: [PATCH] [media] v4l: vsp1: Pass parameter type to entity configuration operation MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Replace the current boolean parameter (full / !full) with an explicit enum. - VSP1_ENTITY_PARAMS_INIT for parameters to be configured at pipeline initialization time only (V4L2 stream on or DRM atomic update) - VSP1_ENTITY_PARAMS_RUNTIME for all parameters that can be freely modified at runtime (through V4L2 controls) This will allow future extensions when implementing image partitioning support.
