From 9f0523de1b7ef122fae527326372a4ab5aa42fa6 Mon Sep 17 00:00:00 2001 From: Jan Kehren Date: Tue, 20 Aug 2024 08:08:50 +0000 Subject: [PATCH 1223/1350] drm: rp1: rp1-dpi: Add DRM_FORMAT_ARGB8888 and DRM_FORMAT_ABGR8888 Android requires this. As the underlying hardware doesn't support alpha blending, we ignore the alpha value.
