From 0fb2970b4b6bfc26817a731b8bc29a9bf9177c20 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 6 Jun 2015 21:46:53 +0100 Subject: [PATCH] drm/armada: remove non-component support Now that the transition of TDA998x to the component helpers is complete, remove the non-componentised support from the Armada DRM driver. All outputs are expected to use the component helpers from now on.
