Subject: [PATCH v2 13/15] staging: fsl-mc: move mc-sys.h contents in the public header
From: Laurentiu Tudor <laurentiu.tudor@....com>
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.
Signed-off-by: Laurentiu Tudor <laurentiu.tudor@....com>
