Subject: [PATCH 08/13] fsl/fman: add API to get the device behind a fman port
Date: Fri, 29 Mar 2019 16:00:09 +0200 [thread overview]
Message-ID: <20190329140014.8126-9-laurentiu.tudor@nxp.com> (raw)
In-Reply-To: <20190329140014.8126-1-laurentiu.tudor@nxp.com>
From: Laurentiu Tudor <laurentiu.tudor@nxp.com>
Add an API that retrieves the 'struct device' that the specified fman
port probed against. The new API will be used in a subsequent iommu
enablement related patch.
