Subject: [PATCH v2 4/9] fsl/fman: add API to get the device behind a fman port
Date: Sat, 27 Apr 2019 10:10:26 +0300 [thread overview]
Message-ID: <20190427071031.6563-5-laurentiu.tudor@nxp.com> (raw)
In-Reply-To: <20190427071031.6563-1-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.
