From f54a5990c32978dcb84ef1d38d22457bf3129797 Mon Sep 17 00:00:00 2001 From: Lubomir Rintel Date: Mon, 21 Jan 2019 07:01:57 +0100 Subject: drm/armada: replace the simple-framebuffer If there's a simple-framebuffer carried over from boot firmware, it's going to stop working once we setup the LCDC for use via DRM. Kick it off from the hardware.
