Subject: [PATCH v6 1/3] dt-bindings: PCI: qcom: ep: Add interconnects path

Some platforms may not boot if a device driver doesn't
initialize the interconnect path. Mostly it is handled
by the bootloader but we have starting to see cases
where bootloader simply ignores them.

Add the "pcie-mem" interconnect path as a required property
to the bindings.

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/[email protected]

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Hi Rob,

Can you please verify again I don't see any errors when I ran it
