[PATCH 2/8] arm64: dts: rockchip: Refactor DSI nodes on rk3399 boards
Diederik de Haas

Fri Jun 27 08:16:21 PDT 2025
The #address-cells and #size-cells properties are not useful on the DSI
controller nodes; they are only useful/required on ports and panel(s).
So remove them from the controller node and add them where actually
needed on the various rk3399 based boards.
Next to that, there were several (exact) redefinitions of nodes which
are already present in rk3399-base.dtsi to add a mipi_out endpoint.
Simplify that by referencing the mipi_out phandle and add the endpoint
to that, which allows the removeal of the ports redefinition.
And fix 1 instance where the mipi_out referenced node was not sorted
correctly.
This fixes the following DTB validation warnings:
unnecessary #address-cells/#size-cells without "ranges",
"dma-ranges" or child "reg" property
