| Subject: [media] 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. |
