PATCH 1/1 dt-bindings: interconnect: qcom: Do not require reg for sc8180x virt NoCs

From: Georgi Djakov <[email protected]>

The virtual interconnect providers do not have their own IO address space, but this is not documented in the DT schema and the following warnings are reported by dtbs_check:

sc8180x-lenovo-flex-5g.dtb: interconnect-camnoc-virt: 'reg' is a required property sc8180x-lenovo-flex-5g.dtb: interconnect-mc-virt: 'reg' is a required property sc8180x-lenovo-flex-5g.dtb: interconnect-qup-virt: 'reg' is a required property sc8180x-primus.dtb: interconnect-camnoc-virt: 'reg' is a required property sc8180x-primus.dtb: interconnect-mc-virt: 'reg' is a required property sc8180x-primus.dtb: interconnect-qup-virt: 'reg' is a required property

Fix this by adding them to the list of compatibles that do not require the reg property.

So I guess we are giving up on

Thanks for the pointer! That approach is fine too, but i was expecting a re-send and then later completely forgot about it. I have a slight preference towards my patch, because it is more compact, but i can also revive Vinod's patch if you think that it would be a better pattern to follow in the long term.

BR,
Georgi

Vinod sent his patch more than a year ago, so I think we are indeed giving up on this :)
