Martyn Welch b5bc980a49 docs: Add kernel-doc comments to VME driver API
Add kernel-doc comments to the VME driver API and structures. This
documentation will be integrated into the RST documentation in a later
patch.

Martyn Welch b0f2d7d546 VME: Remove node entry from vme_driver
The vme_driver structure currently has a "node" entry. This entry is
never used and it's intended purpose has been lost to the mists of time.

Remove the entry from vme_driver to avoid confusion.

Martyn Welch 8d7cc7adce VME: Remove shutdown entry from vme_driver
The vme_driver structure currently has a "shutdown" entry. This entry is
never used, it lacks the correct parameter (it should be providing a
pointer to the relevant vme_dev struct to even *look* usable), the VME
subsystem currently doesn't provide support for shutdown functions and no
in-tree drivers use it (hardly surprising, given it'd never be called).

Remove the entry from vme_driver to avoid confusion.

Aaron Sierra fa54b32680 vme: change LM callback argument to void pointer
Make the location monitor callback function prototype more useful by
changing the argument from an integer to a void pointer.

All VME bridge drivers were simply passing the location monitor index
(e.g. 0-3) as the argument to these callbacks. It is much more useful
to pass back a pointer to data that the callback-registering driver
cares about.

There appear to be no in-kernel callers of vme_lm_attach (or
vme_lme_request for that matter), so this change only affects the VME
subsystem and bridge drivers.

This has been tested with Tsi148 hardware, but the CA91Cx42 changes
have only been compiled.

We also make sure that user won't be able to reconfigure the window while it is
mmap'ed.

Martyn Welch d7729f0fc4 VME: Rename vme_slot_get to avoid confusion with reference counting
Traditionally the "get" functions increment the reference count of the
object that is returned, which does not happen with vme_slot_get. The
function vme_slot_get returns the physical VME slot associated with a
particular struct vme_dev. Rename vme_slot_num to avoid any confusion.

Martyn Welch 978f47d643 VME: Provide access to VME bus enumeration and fix vme_user match function
The match function for vme_user is completely wrong. It will blindly bind
against the first VME slot on each bus (at this point that would be just the
first bus as the driver can only handle one bus).

The original intention (before some major subsystem changes) was that the
driver bind against the slot to which the bridge was attached in the VME
system and to the bus(es) provided via the "bus" module parameter.

To do this cleanly (i.e. without poking arround in the subsystems internal
stuctures) a functionality has been added to provide access to the bus
enumeration.

Greg Kroah-Hartman db3b9e990e Staging: VME: move VME drivers out of staging
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.
