From 87969338436710638076d8083dda8b0de703f4a5 Mon Sep 17 00:00:00 2001 From: Icenowy Zheng <icenowy@aosc.io> Date: Wed, 17 May 2017 22:47:17 +0800 Subject: drm/sun4i: abstract a engine type As we are going to add support for the Allwinner DE2 engine in sun4i-drm driver, we will finally have two types of display engines -- the DE1 backend and the DE2 mixer. They both do some display blending and feed graphics data to TCON, and is part of the "Display Engine" called by Allwinner, so I choose to call them both "engine" here. Abstract the engine type to a new struct with an ops struct, which contains functions that should be called outside the engine-specified code (in TCON, CRTC or TV Encoder code). In order to preserve bisectability, we also switch the backend and layer code in its own module.
