Subject: [PATCH 2/2] dt-bindings: arm: coresight-tmc: Add 'iommu' property
Date: Thu, 21 Jul 2022 15:27:15 -0600 [thread overview]
Message-ID: <20220721212718.1980905-2-robh@kernel.org> (raw)
In-Reply-To: <20220721212718.1980905-1-robh@kernel.org>
The Coresight TMC component may be behind an IOMMU which is the case for
the Arm Juno SoC and some Qualcomm SoCs. Add 'iommus' property to the
binding.
