2012-04-26Staging: VME: move VME drivers out of stagingGreg Kroah-Hartman
This moves the VME core, VME board drivers, and VME bridge drivers out of the drivers/staging/vme/ area to drivers/vme/. The VME device drivers have not moved out yet due to some API questions they are still working through, that should happen soon, hopefully.

2011-10-17staging: vme: make match() driver specific to improve non-VME64x supportManohar Vanga
For jumper based boards (non VME64x), there is no mechanism for detecting the card that is plugged into a specific slot. This leads to issues in non-autodiscovery crates/cards when a card is plugged into a slot that is "claimed" by a different driver. In reality, there is no problem, but the driver rejects such a configuration due to its dependence on the concept of slots. This patch makes the concept of slots less critical and pushes the driver match() to individual drivers (similar to what happens in the ISA bus in driver/base/isa.c). This allows drivers to register the number of devices that they expect without any restrictions. Devices in this new model are now formatted as $driver_name-$bus_id.$device_id (as compared to the earlier vme-$bus_id.$slot_number). This model also makes the device model more logical as devices are only registered when they actually exist whereas earlier, a set of devices were being created automatically regardless of them actually being there. Another change introduced in this patch is that devices are now created within the VME driver structure rather than in the VME bridge structure. This way, things don't go haywire if the bridge driver is removed while a driver is using it.

2011-10-17staging: vme: add struct vme_dev for VME devicesManohar Vanga
Instead of using a vanilla 'struct device' for VME devices, add new 'struct vme_dev'. Modifications have been made to the VME framework API as well as all in-tree VME drivers. The new vme_dev structure has the following advantages from the current model used by the driver: * Driver functions (probe, remove) now receive a VME device instead of a pointer to the bridge device (cleaner design) * It's easier to differenciate API calls as bridge-based or device-based (ie. cleaner interface).

2011-09-09staging: vme: change static device array to pointersManohar Vanga
Change the static array of 'struct device''s in struct vme_bridge to instead use an array of pointers. This is in accordance with the requirement that all kobjects be dynamically allocated (see Documentation/kobject.txt) and never be statically allocated.

2011-08-23staging: vme: keep track of registered busesManohar Vanga
This patch adds a list which keeps track of all registered VME buses. This is required for adding refcounting later to bridge modules, something that is not currently implemented.

By removing the dependency of the VME bridge framework on PCI, this patch allows for addition of non-PCI based VME bridges.
