From 1d2c1f74c8e7b33ab0d121ff0af74d4aee193316 Mon Sep 17 00:00:00 2001 From: Benoit Parrot Date: Fri, 18 Nov 2016 21:20:13 -0200 Subject: [PATCH] [media] media: ti-vpe: vpdma: Add helper to set a background color Add a helper to set the background color during vpdma transfer. This is needed when VPDMA is generating 32 bits RGB format to have the Alpha channel set to an appropriate value.
