From 9c5d91f6b938c23065ddc21c8654c5e222c35687 Mon Sep 17 00:00:00 2001 From: Jan Kehren Date: Fri, 16 Aug 2024 13:47:50 +0000 Subject: [PATCH 1222/1350] drm: rp1: rp1-dsi: 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.
