Subject: [RFC v4 4/8] passthrough/arm: Modify SMMU driver to use generic device definition
Date: Mon, 18 Dec 2017 20:16:59 -0700 [thread overview]
Message-ID: <20171219031703.23420-5-sameer.goel@linaro.org> (raw)
In-Reply-To: <20171219031703.23420-1-sameer.goel@linaro.org>
Modify the SMMU code to use generic device instead of dt_device_node for
functions that can be used for ACPI based systems too.
