The Allwinner SoCs have a display engine composed of several controllers
assembled differently depending on the SoC, the number and type of output
they have, and the additional features they provide. A number of those are
supported in Linux, with the matching bindings.

Now that we have the DT validation in place, let's split into separate file
and convert the device tree bindings for those controllers to schemas.

Changes from v2:
  - Changed a number of maxItems to minItems to make more sense
  - Fixed a few enum that were improperly declared. This raised a bunch of
    warnings that were unnoticed before. Fixed them.
  - Added an if clause to the HDMI PHY binding to check the number of clocks

Changes from v1:
  - Declare the ports in the bindings

+
+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]

+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

-
-- 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:

* [PATCH v3 1/4] dt-bindings: display: Convert Allwinner display pipeline to schemas

The Allwinner SoCs have a display engine composed of several controllers
assembled differently depending on the SoC, the number and type of output
they have, and the additional features they provide. A number of those are
supported in Linux, with the matching bindings.

Now that we have the DT validation in place, let's split into separate file
and convert the device tree bindings for those controllers to schemas.

Changes from v2:
  - Changed a number of maxItems to minItems to make more sense
  - Fixed a few enum that were improperly declared. This raised a bunch of
    warnings that were unnoticed before. Fixed them.
  - Added an if clause to the HDMI PHY binding to check the number of clocks

Changes from v1:
  - Declare the ports in the bindings

+
+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
+                   / \

+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

-
-- 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:

-    * 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
