From 0cf9f5096da2200b52cee0e38139c99c4fc0151c Mon Sep 17 00:00:00 2001 From: Laurentiu Tudor Date: Tue, 27 Jun 2017 17:41:24 +0300 Subject: [PATCH] staging: fsl-mc: decouple the mc-bus public headers from dprc.h In its current form, the public headers of the mc-bus depend only on a structure "dprc_obj_desc" defined in dprc.h. Move it to the bus public header together with its associated defines and, in order to keep the naming prefixes consistent rename it to "fsl_mc_obj_desc". This will allow making dprc.h private in future patches.
