From 8a927d648c2ee20f2fd746d733c5cd76d0fbb0c1 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Thu, 15 Mar 2018 11:09:35 +0100 Subject: drm/tegra: plane: Fix RGB565 format on older Tegra The opaque/alpha format conversion code is currently only looking at XRGB formats because they have an equivalent ARGB format. The opaque format for RGB565 is RGB565 itself, much like the YUV formats map to themselves.
