Subject: [PATCH v2 04/27] dt-bindings: display: sunxi-drm: Add TCON TOP description
Date: Tue, 12 Jun 2018 22:00:13 +0200 [thread overview]
Message-ID: <20180612200036.21483-5-jernej.skrabec@siol.net> (raw)
In-Reply-To: <20180612200036.21483-1-jernej.skrabec@siol.net>
TCON TOP main purpose is to configure whole display pipeline. It
determines relationships between mixers and TCONs, selects source TCON
for HDMI, muxes LCD and TV encoder GPIO output, selects TV encoder
clock source and contains additional TV TCON and DSI gates.

+TCON TOP
+--------
+
+TCON TOPs main purpose is to configure whole display pipeline. It determines
+relationships between mixers and TCONs, selects source TCON for HDMI, muxes
+LCD and TV encoder GPIO output, selects TV encoder clock source and contains
+additional TV TCON and DSI gates.
+
+It allows display pipeline to be configured in very different ways:
+
+ / LCD0/LVDS0
+ / TCON-LCD0
+ | \ MIPI DSI
+ mixer0 |
+ \ / TCON-LCD1 - LCD1/LVDS1
+ TCON-TOP
+ / \ TCON-TV0 - TVE0/RGB
+ mixer1 | \
+ | TCON-TOP - HDMI
+ | /
+ \ TCON-TV1 - TVE1/RGB
+
+Note that both TCON TOP references same physical unit.
+
+Required properties:
+ - compatible: value must be one of:
+ * allwinner,sun8i-r40-tcon-top
+ - reg: base address and size of the memory-mapped region.
+ - clocks: phandle to the clocks feeding the TCON TOP
+ * bus: TCON TOP interface clock
+ - clock-names: clock name mentioned above
+ - resets: phandle to the reset line driving the DRC
+ * rst: TCON TOP reset line
+ - reset-names: reset name mentioned above
+ - #clock-cells : must contain 1
+
+- ports: A ports node with endpoint definitions as defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt. The first port
+ should be the input for mixer0 mux. The second should be the output for that
+ mux. Third port should be input for mixer1 mux. Fourth port should be output
+ for mixer1 mux. Fifth port should be input for HDMI mux. Sixth port should
+ be output for it. All output endpoints should have reg property with the id
+ of the target TCON. All ports should have only one enpoint connected to
+ remote endpoint.
