2017-11-18rapidio: constify rio_device_idArvind Yadav1-1/+1
rio_device_id are not supposed to change at runtime. rio driver is working with const 'id_table'. So mark the non-const rio_device_id structs as const.

2013-07-04rapidio: convert switch drivers to modulesAlexandre Bounine1-16/+70
Rework RapidIO switch drivers to add an option to build them as loadable kernel modules. This patch removes RapidIO-specific vmlinux section and converts switch drivers to be compatible with LDM driver registration method. To simplify registration of device-specific callback routines this patch introduces rio_switch_ops data structure. The sw_sysfs() callback is removed from the list of device-specific operations because under the new structure its functions can be handled by switch driver's probe() and remove() routines. If a specific switch device driver is not loaded the RapidIO subsystem core will use default standard-based operations to configure a switch. Because the current implementation of RapidIO enumeration/discovery method relies on availability of device-specific operations for error management, switch device drivers must be loaded before the RapidIO enumeration/discovery starts. This patch also moves several common routines from enumeration/discovery module into the RapidIO core code to make switch-specific operations accessible to all components of RapidIO subsystem.

2011-05-18rapidio: fix default routing initializationAlexandre Bounine1-0/+6
Fix switch initialization to ensure that all switches have default routing disabled. This guarantees that no unexpected RapidIO packets arrive to the default port set by reset and there is no default routing destination until it is properly configured by software. This update also unifies handling of unmapped destinations by tsi57x, IDT Gen1 and IDT Gen2 switches.

2011-01-13rapidio: use common destid storage for endpoints and switchesAlexandre Bounine1-5/+1
Change code to use one storage location common for switches and endpoints. This eliminates unnecessary device type checks during basic access operations. Logic that assigns destid to RIO devices stays unchanged - as before, switches use an associated destid because they do not have their own.

2010-05-27rapidio: add IDT CPS/TSI switchesAlexandre Bounine1-0/+89
Extentions to RapidIO switch support: 1. modify switch route operation declarations to allow using single switch-specific file for family of switches that share the same route table operations. 2. add standard route table operations for switches that that support route table manipulation registers as defined in the Rev.1.3 of RapidIO specification. 3. add clear-route-table operation for switches 4. add CPSxx and TSIxxx families of RapidIO switches Signed-off-by: Alexandre Bounine <alexandre.bounine@idt.com> Tested-by: Thomas Moll <thomas.moll@sysgo.com> Cc: Matt Porter <mporter@kernel.crashing.org> Cc: Li Yang <leoli@freescale.com> Cc: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
