-From: Laurentiu Tudor <laurentiu.tudor@nxp.com>
-Date: Mon, 16 Apr 2018 12:26:38 +0300
-Subject: [PATCH] bus: fsl-mc: Some apis are made public for vfio
-
-Some of the APIs and data-structures are required for VFIO.
-This patch moves dprc.h to public header files.
-Also some APIs of mc-bus are made public for vfio.
