[PATCH 09/10] ARM: dts: sun7i: Add device nodes for display pipelines

Chen-Yu Tsai wens at csie.org
Tue Oct 17 05:18:06 PDT 2017


From: Jonathan Liu <net147 at gmail.com>

The A20 has two interconnected display pipelines, mirroring the A10.

Add all the device nodes for them, including the downstream HDMI
controller that we already support.
