From 2b034b00e827dfde8245f542820fc142cd09b4ad Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 5 Mar 2014 15:49:19 -0300 Subject: [PATCH] v4l: vsp1: uds: Enable scaling of alpha layer 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.
