From 490f50c109d1178aae4124cd9138b231d030e554 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Mon, 25 Mar 2019 15:18:18 +0100 Subject: [PATCH] drm/meson: Add G12A support for OSD1 Plane Amlogic G12A SoC supports now up to 3 OSD planes (1 more than the previous SoCs) and a brand new OSD plane blender module. This patch uses the same OSD1 plane for G12A, using the exact same scaler and OSD1 setup registers, except using the new blender register to disable the plane.
