From 2c03e2fb063f33694e35bbade6d9186274b9a02f Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Fri, 21 Apr 2017 16:38:53 +0800 Subject: drm/sun4i: backend: Save pointer to device tree node Save a pointer to the backend's underlying device tree node in its data structure. This will be used later for downstream tcons to find and match their respective upstream backends.
