From d27d7c25c946776c015a39f1a9eb0c6d4e724a70 Mon Sep 17 00:00:00 2001
From: Liu Ying <victor.liu@nxp.com>
Date: Fri, 25 Jan 2019 11:23:39 +0800
Subject: [PATCH] drm/imx: Revert a patch which merges imx-drm-core and
ipuv3-crtc in one module
DPU CRTC found in i.MX8qm/qxp SoCs can be hooked into imx-drm.
Thus, move ipuv3-crtc out of imx-drm-core.
Revert "drm/imx: merge imx-drm-core and ipuv3-crtc in one module"
This reverts commit 3d1df96ad46856ce850be5ac112eab919cbe1cab.
