This converts the Synopsis MIPI DSI binding documentation to
yaml and should be quite straightforward. I've added a missing
ref clk and also added Mark and Rob as maintainers based on
'get_maintainer.pl' results.

+maintainers: + - Rob Herring <robh+dt@xxxxxxxxxx>
No thanks, I don't know anything about this hardware. It should
be the owner for this binding, not who applies patches.
Sorry about that, I just followed what get_maintainer.pl -f
returned.
I'm not sure I understand the owner vs maintainers difference for
the "maintainers" entry. How do I find out who is the owner?
Looking at the git log, this file was touched only once when added
in 88dd1e6f9ad8 ("dt-bindings: display: Add Synopsys DW MIPI DSI
host controller") by Philippe CORNU <philippe.cornu@xxxxxx>.
Is the person who added the file automatically owner?
(cc'd Philippe)

Check current maintainers. Mark is not one anymore.
Yes, I just noticed he got removed in my latest next-20200416
tree, thanks.

Need to reference ($ref) dsi-controller.yaml here.

Drop the description. That's every 'reg'. You need to say how many
regions (maxItems: 1?).
+
+ clocks:
+ description: |
+ References to all the clocks specified in the clock-names property as
+ specified in Documentation/devicetree/bindings/clock/clock-bindings.txt
Drop
+ items:
+ - description: Module clock
+ - description: DSI bus colck for either AHB and APB
typo
+ - description: Pixel clock for the DPI/RGB input
+ minItems: 2
+ maxItems: 3
You can drop 'maxItems'. It's implied by the length of 'items'.
+
+ clock-names:
+ items:
+ - const: ref
+ - const: pclk
+ - const: px_clk
+ minItems: 2
+ maxItems: 3
+
+ resets:

+ References to all the resets specified in the reset-names property as
+ specified in Documentation/devicetree/bindings/reset/reset.txt
Drop.
You need maxItems to define how many reset entries.
+
+ reset-names:
+ const: apb
+
+patternProperties:
+ "^panel@[0-3]$":
+ type: object
+ description: |
+ A node containing the panel or bridge description as documented in
bridge? But the node name says panel only.

Drop description.
