From a43a42ad9ceae94eca1a80ef072d6a19f0160a57 Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Wed, 17 May 2017 22:47:19 +0800 Subject: drm/sun4i: add a Kconfig option for sun4i-backend As sun4i-backend is now a dedicated module, add an Kconfig option for it to make it optional, since some build may only use other engines.
