From 0efb6fd36644a4ba743e26ea7ac532a9d539a3ee Mon Sep 17 00:00:00 2001 From: Takanari Hayama Date: Wed, 10 Aug 2022 17:37:09 +0900 Subject: media: vsp1: Add premultiplied alpha support To support DRM blend mode in R-Car DU driver, we must be able to pass a plane with the premultiplied alpha. Adding a new property to vsp1_du_atomic_config allows the R-Car DU driver to pass the premultiplied alpha plane.
