From 27cfdadd687deca58146b415f60b23d185cb3532 Mon Sep 17 00:00:00 2001 From: Ioana Ciornei Date: Tue, 3 Aug 2021 19:57:42 +0300 Subject: [PATCH] bus: fsl-mc: extend fsl_mc_get_endpoint() to pass interface ID In case of a switch DPAA2 object, the interface ID is also needed when querying for the object endpoint. Extend fsl_mc_get_endpoint() so that users can also pass the interface ID that are interested in. Signed-off-by: Ioana Ciornei Signed-off-by: David S.
