From: Neil Armstrong Date: Mon, 25 Mar 2019 14:18:19 +0000 (+0100) Subject: drm/meson: Add G12A Support for the Overlay video plane X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=11c2d4c751e5b339f8a3c6b9f19120bb331af0ef;p=openwrt%2Fstaging%2Fblogic.git drm/meson: Add G12A Support for the Overlay video plane Amlogic G12A SoC supports the same set of Video Planes, but now are handled by the new OSD plane blender module. This patch uses the same VD1 plane for G12A, using the exact same scaler and VD1 setup registers, except using the new blender register to disable the plane.
