From 1837379e95565bc5956ba2c8abc2ec43471dab46 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Fri, 23 Jun 2017 16:20:47 +0300 Subject: v4l: vsp1: Add support for multiple DRM pipelines The R-Car H3 ES2.0 VSP-DL instance has two LIF entities and can drive two display pipelines at the same time. Refactor the VSP DRM code to support that by introducing a vsp_drm_pipeline object that models one display pipeline.
