Subject: [PATCH v5 01/14] Documentation: of: add type property


From: Kuninori Morimoto <kuninori.morimoto.gx@...esas.com>

OF graph indicates each devices connection. But it doesn't support type
of each port. For example HDMI case, it has video port and sound port
in one device node.
In this case, current driver can't handle each port correctly.
This patch enables to use type property on OF graph.

+port / endpoint type
+--------------------
+
+Each port can have its type if needed.
+For example HDMI case, it has video port and sound port.
+Below example indicates that port@0 is HDMI-video port,
+and port@1 is HDMI-sound port.
+
+HDMI {
+	port@0 {
+		type = "video";
+		endpoint {
+		};
+	};
+	port@1 {
+		type = "sound";
+		endpoint {
+		};
+	};
+};
