* rapidio: rework device hierarchy and introduce mport class of devicesAlexandre Bounine2014-04-071-8/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* RapidIO: add mport driver for Tsi721 bridgeAlexandre Bounine2011-11-021-0/+49
| | | | | | | | | | | | | | | | | Add RapidIO mport driver for IDT TSI721 PCI Express-to-SRIO bridge device. The driver provides full set of callback functions defined for mport devices in RapidIO subsystem. It also is compatible with current version of RIONET driver (Ethernet over RapidIO messaging services). This patch is applicable to kernel versions starting from 2.6.39.
