[PATCH 07/10] ARM: dts: sun4i: Add device nodes for display pipelines
Chen-Yu Tsai
wens at csie.org
Tue Oct 17 05:18:04 PDT 2017
The A10 has two interconnected display pipelines, much like the A31,
but without the DRCs between the backend and TCONs.
Add all the device nodes for them, including the downstream HDMI
controller that we already support.
