Subject: [media] v4l: vsp1: uds: Enable scaling of alpha layer Author: Laurent Pinchart <[email protected]> Date: Wed Mar 5 15:49:19 2014 -0300 Scaling of the alpha layer is disabled as both the RPF and WPF are configured to hardcode the alpha value to 255. This results in a 0 alpha value at the UDS output, making the image invisible when alpha blended in the BRU. Fix it by enabling scaling of the alpha layer.
