"Add compatible for the HDPTX PHY on rk3576, which is fully compatible
with foo bar."

One sentence.

Why items?

Why enum?

> +              - rockchip,rk3576-hdptx-phy

So that's just enum with previous entry... but you said compatible, yet
nothing is here. Test your patches - DTS will fail on this. Driver as
well (assuming you expressed properly compatibility).

Krzysztof

Is this the right way to write it ？：

properties:
   compatible:
-    enum:
-      - rockchip,rk3588-hdptx-phy
+    oneOf:
+      - enum:
+          - rockchip,rk3588-hdptx-phy
+      - items:
+          - enum:
+              - rockchip,rk3576-hdptx-phy

Yes, assuming they are compatible.

Also: where are any users of this binding?

We don't take bindings without *UPSTREAM* users.

Andy, can you do a (separate) DTS series that binds all the display stuff
together on one rk3576 board? (iommu, hdptxphy, vop, hdmi)

Depending on how the driver sides go, this may be need to be revised at
the end, but should hopefully satisfy that "show a user" thing.

I guess Kever's EVB-series [0] might be a good base to build upon, with it
being a Rockchip EVB?


For people reading along, that whole display chain consists of:
- iommu [1]
- core display-controller additions for the rk3576 [2]
- this hdptxphy binding
- additions for the dw-hdmi-qp glue [3]

As EVB patch series is still WIP, I will use rk3576-armsom-sige5.dts which is already
in mainline as the base to collect all display related dts。
