Re: [PATCH 1/2] dt-bindings: Add Arm SMMUv3 PMCG binding

On Tue, 16 Nov 2021 11:35:36 +0000, Jean-Philippe Brucker wrote:

Add binding for the Arm SMMUv3 PMU. Each node represents a PMCG, and is
placed as a sibling node of the SMMU. Although the PMCGs registers may
be within the SMMU MMIO region, they are separate devices, and there can
be multiple PMCG devices for each SMMU (for example one for the TCU and
one for each TBU).

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/1555758

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

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.
