From 2aaf308b95b24649a6dcfed89cd956e972089b2a Mon Sep 17 00:00:00 2001 From: Alexandre Bounine Date: Mon, 7 Apr 2014 15:38:56 -0700 Subject: rapidio: rework device hierarchy and introduce mport class of devices This patch removes an artificial RapidIO bus root device and establishes actual device hierarchy by providing reference to real parent devices. It also introduces device class for RapidIO controller devices (on-chip or an eternal bridge, known as "mport"). Existing implementation was sufficient for SoC-based platforms that have a single RapidIO controller. With introduction of devices using multiple RapidIO controllers and PCIe-to-RapidIO bridges the old scheme is very limiting or does not work at all. The implemented changes allow to properly reference platform's local RapidIO mport devices and provide device details needed for upper layers. This change to RapidIO device hierarchy does not break any known existing kernel or user space interfaces.
