Subject: [media] v4l: vsp1: Add global alpha support for DRM pipeline Author: Laurent Pinchart <[email protected]> Date: Thu Mar 24 05:15:59 2016 -0300 Make the global alpha multiplier of DRM planes configurable. All the necessary infrastructure is there, we just need to store the alpha value passed through the DRM API.
