The VOP2 is the display output controller on the RK3568. Add the node
for it to the dtsi file along with the required display-subsystem node
and the iommu node.

Some DT sort rules:

For nodes:
Sort things without reg alphabetical first,
then sort the rest by reg address.

From rockchip-vop2.yaml:
+properties:
+  compatible:
+    enum:

+      - rockchip,rk3568-vop
+      - rockchip,rk3566-vop

Maybe sort yaml compatibles in alphabetical order.

rockchip,rk3566-vop is not used in the dtsi I think.

Question:
Given Andy's comment could someone explain weather the vop and hdmi
nodes should be in rk3566.dtsi and rk3568.dtsi with an extra
rockchip,rk3566-dw-hdmi compatible?

Heiko's sort rules:

compatible
reg
interrupts
[alphabetical]
status [if needed]

My incomplete list:

Inside nodes:
If exists on top: compatible, reg and interrupts.
In alphabetical order the required properties.
Then in alphabetical order the other properties.
And as last things that start with '#' in alphabetical order.
Add status below all other properties for soc internal components with
any board-specifics.

We could put the vop/hdmi nodes into rk356x.dtsi and just add the
compatible properties to rk3566.dtsi and rk3568.dtsi.
We'll need the exact SoC type, besides the mirror lock thingy there are a
few other minor differences between the SoCs.

sounds about right. We have similar solutions in place in other socs.
