Subject: [PATCH v3 18/28] dt-bindings: display: sunxi: add DT binding for Allwinner H6 DW HDMI

From: Icenowy Zheng <icenowy@aosc.io>

The Allwinner H6 SoC uses a v2.12a DesignWare HDMI controller, with
dedicated CEC and HDCP clocks added; the PHY connected is a standard
DesignWare HDMI PHY.

Add binding for it.
