Subject: [PATCH 10/21] fsl/fman: add API to get the device behind a fman port
Date: Wed, 19 Sep 2018 15:36:02 +0300	[thread overview]
Message-ID: <20180919123613.15092-11-laurentiu.tudor@nxp.com> (raw)
In-Reply-To: <20180919123613.15092-1-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.
