From 7d6e221d73904aedcbd46ce2db6a545be55d2296 Mon Sep 17 00:00:00 2001 From: Laurentiu Tudor Date: Thu, 22 Jun 2017 16:35:58 +0300 Subject: [PATCH] staging: fsl-mc: move mc-sys.h contents in the public header mc-sys.h contains the API to send commands to the MC and is used by drivers. Move it to the public headers and get rid of the mc-sys.h header.
