+
+maintainers:

+ - Maxime Ripard <mripard@kernel.org>
+
+description: |
+ The display engine pipeline (and its entry point, since it can be
+ either directly the backend or the frontend) is represented as an
+ extra node.
+
+ The Allwinner A10 Display pipeline is composed of several components
+ that are going to be documented below:
+
+ For all connections between components up to the TCONs in the
+ display pipeline, when there are multiple components of the same
+ type at the same depth, the local endpoint ID must be the same as
+ the remote component's index. For example, if the remote endpoint is
+ Frontend 1, then the local endpoint ID must be 1.
+
+ Frontend 0 [0] ------- [0] Backend 0 [0] ------- [0] TCON 0
+ [1] -- -- [1] [1] -- -- [1]
+ \ / \ /
+ X X
+ / \ / \
+ [0] -- -- [0] [0] -- -- [0]
+ Frontend 1 [1] ------- [1] Backend 1 [1] ------- [1] TCON 1
+
+ For a two pipeline system such as the one depicted above, the lines
+ represent the connections between the components, while the numbers
+ within the square brackets corresponds to the ID of the local endpoint.
+
+ The same rule also applies to DE 2.0 mixer-TCON connections:
+
+ Mixer 0 [0] ----------- [0] TCON 0
+ [1] ---- ---- [1]
+ \ /
+ X
+ / \
+ [0] ---- ---- [0]
+ Mixer 1 [1] ----------- [1] TCON 1

+description: |
+ 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
+ / [0] TCON-LCD0
+ | \ MIPI DSI
+ mixer0 |
+ \ / [1] TCON-LCD1 - LCD1/LVDS1
+ TCON-TOP
+ / \ [2] TCON-TV0 [0] - TVE0/RGB
+ mixer1 | \
+ | TCON-TOP - HDMI
+ | /
+ \ [3] TCON-TV1 [1] - TVE1/RGB
+
+ Note that both TCON TOP references same physical unit. Both mixers
+ can be connected to any TCON. Not all TCON TOP variants support all
+ features.

-Allwinner A10 Display Pipeline
-==============================
-
-The Allwinner A10 Display pipeline is composed of several components
-that are going to be documented below:
-
-For all connections between components up to the TCONs in the display
-pipeline, when there are multiple components of the same type at the
-same depth, the local endpoint ID must be the same as the remote
-component's index. For example, if the remote endpoint is Frontend 1,
-then the local endpoint ID must be 1.
-
- Frontend 0 [0] ------- [0] Backend 0 [0] ------- [0] TCON 0
- [1] -- -- [1] [1] -- -- [1]
- \ / \ /
- X X
- / \ / \
- [0] -- -- [0] [0] -- -- [0]
- Frontend 1 [1] ------- [1] Backend 1 [1] ------- [1] TCON 1
-
-For a two pipeline system such as the one depicted above, the lines
-represent the connections between the components, while the numbers
-within the square brackets corresponds to the ID of the local endpoint.
-
-The same rule also applies to DE 2.0 mixer-TCON connections:
-
- Mixer 0 [0] ----------- [0] TCON 0
- [1] ---- ---- [1]
- \ /
- X
- / \
- [0] ---- ---- [0]
- Mixer 1 [1] ----------- [1] TCON 1

- - pll-1: second possible phy clock parent (A64/R40 only)
-
-TV Encoder
-----------
-
-The TV Encoder supports the composite and VGA output. It is one end of
-the pipeline.
-
-Required properties:
- - compatible: value should be "allwinner,sun4i-a10-tv-encoder".
- - reg: base address and size of memory-mapped region
- - clocks: the clocks driving the TV encoder
- - resets: phandle to the reset controller driving the encoder
-
-- ports: A ports node with endpoint definitions as defined in
- Documentation/devicetree/bindings/media/video-interfaces.txt. The
- first port should be the input endpoint.
-
-TCON
-----
-
-The TCON acts as a timing controller for RGB, LVDS and TV interfaces.
-
-Required properties:
- - compatible: value must be either:
- * allwinner,sun4i-a10-tcon
- * allwinner,sun5i-a13-tcon

- * "allwinner,sun50i-a64-tcon-tv", "allwinner,sun8i-a83t-tcon-tv"
- * allwinner,sun50i-h6-tcon-tv, allwinner,sun8i-r40-tcon-tv
- - reg: base address and size of memory-mapped region
- - interrupts: interrupt associated to this IP
- - clocks: phandles to the clocks feeding the TCON.
- - 'ahb': the interface clocks
- - 'tcon-ch0': The clock driving the TCON channel 0, if supported
- - resets: phandles to the reset controllers driving the encoder
- - "lcd": the reset line for the TCON
- - "edp": the reset line for the eDP block (A80 only)
-
- - clock-names: the clock names mentioned above
- - reset-names: the reset names mentioned above
- - clock-output-names: Name of the pixel clock created, if TCON supports
- channel 0.
-
-- ports: A ports node with endpoint definitions as defined in
- Documentation/devicetree/bindings/media/video-interfaces.txt. The
- first port should be the input endpoint, the second one the output
-
- The output may have multiple endpoints. TCON can have 1 or 2 channels,
- usually with the first channel being used for the panels interfaces
- (RGB, LVDS, etc.), and the second being used for the outputs that
- require another controller (TV Encoder, HDMI, etc.). The endpoints
- will take an extra property, allwinner,tcon-channel, to specify the
- channel the endpoint is associated to. If that property is not
- present, the endpoint number will be used as the channel number.
-
-For TCONs with channel 0, there is one more clock required:
- - 'tcon-ch0': The clock driving the TCON channel 0
-For TCONs with channel 1, there is one more clock required:
- - 'tcon-ch1': The clock driving the TCON channel 1
-
-When TCON support LVDS (all TCONs except TV TCONs on A83T, R40 and those found
-in A13, H3, H5 and V3s SoCs), you need one more reset line:
- - 'lvds': The reset line driving the LVDS logic
-
-And on the A23, A31, A31s and A33, you need one more clock line:
- - 'lvds-alt': An alternative clock source, separate from the TCON channel 0
- clock, that can be used to drive the LVDS clock
-
-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
- / [0] TCON-LCD0
- | \ MIPI DSI
- mixer0 |
- \ / [1] TCON-LCD1 - LCD1/LVDS1
- TCON-TOP
- / \ [2] TCON-TV0 [0] - TVE0/RGB
- mixer1 | \
- | TCON-TOP - HDMI
- | /
- \ [3] TCON-TV1 [1] - TVE1/RGB
-
-Note that both TCON TOP references same physical unit. Both mixers can be
-connected to any TCON. Not all TCON TOP variants support all features.
-
-Required properties:
- - compatible: value must be one of:
- * allwinner,sun8i-r40-tcon-top
- * allwinner,sun50i-h6-tcon-top
- - reg: base address and size of the memory-mapped region.
- - clocks: phandle to the clocks feeding the TCON TOP

- - clock-names: clock name mentioned above
- - resets: phandle to the reset line driving the TCON TOP
- - #clock-cells : must contain 1
- - clock-output-names: Names of clocks created for TCON TV0 channel clock,
- TCON TV1 channel clock (R40 only) and DSI channel clock (R40 only), in
- that order.
-
-- ports: A ports node with endpoint definitions as defined in
- Documentation/devicetree/bindings/media/video-interfaces.txt. 6 ports should
- be defined:
- * port 0 is input for mixer0 mux
- * port 1 is output for mixer0 mux
- * port 2 is input for mixer1 mux
- * port 3 is output for mixer1 mux
- * port 4 is input for HDMI mux
- * port 5 is output for HDMI mux
- All output endpoints for mixer muxes and input endpoints for HDMI mux should
- have reg property with the id of the target TCON, as shown in above graph
- (0-3 for mixer muxes and 0-1 for HDMI mux). All ports should have only one
- endpoint connected to remote endpoint.

- * This function is called by &drm_atomic_bridge_chain_check() just before

- * It performs bus format negotiation between bridge elements. The negotiation
- * happens in reverse order, starting from the last element in the chain up to
- * @bridge.
- *
- * Negotiation starts by retrieving supported output bus formats on the last
- * bridge element and testing them one by one. The test is recursive, meaning
- * that for each tested output format, the whole chain will be walked backward,
- * and each element will have to choose an input bus format that can be
- * transcoded to the requested output format. When a bridge element does not
- * support transcoding into a specific output format -ENOTSUPP is returned and
- * the next bridge element will have to try a different format. If none of the
- * combinations worked, -ENOTSUPP is returned and the atomic modeset will fail.
- *
- * This implementation is relying on
- * &drm_bridge_funcs.atomic_get_output_bus_fmts() and
- * &drm_bridge_funcs.atomic_get_input_bus_fmts() to gather supported
- * input/output formats.
- *
- * When &drm_bridge_funcs.atomic_get_output_bus_fmts() is not implemented by
- * the last element of the chain, &drm_atomic_bridge_chain_select_bus_fmts()
- * tries a single format: &drm_connector.display_info.bus_formats[0] if
- * available, MEDIA_BUS_FMT_FIXED otherwise.
- *
- * When &drm_bridge_funcs.atomic_get_input_bus_fmts() is not implemented,
- * &drm_atomic_bridge_chain_select_bus_fmts() skips the negotiation on the
- * bridge element that lacks this hook and asks the previous element in the
- * chain to try MEDIA_BUS_FMT_FIXED. It's up to bridge drivers to decide what
- * to do in that case (fail if they want to enforce bus format negotiation, or
- * provide a reasonable default if they need to support pipelines where not
- * all elements support bus format negotiation).
