From 3e81374e2014c42abff62cb74b654c6d4fb269ee Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Mon, 26 Jun 2017 13:12:01 +0300 Subject: drm: rcar-du: Support multiple sources from the same VSP On R-Car H3 ES2.0, DU channels 0 and 3 are served by two separate pipelines from the same VSP. Support this in the DU driver.
