[PATCH v2 12/13] ARM: dts: sun6i: Add device node for HDMI controller

From: Chen-Yu Tsai <hidden>
Date: 2017-09-26 07:00:56
Also in: dri-devel, linux-arm-kernel, linux-clk, lkml
Subsystem: the rest · Maintainer: Linus Torvalds

Now that we support the HDMI controller on the A31 SoC, we can add it
to the device tree.

This adds a device node for the HDMI controller, and the of_graph nodes
connecting it to the 2 TCONs.
