2017-03-17docs: Add kernel-doc comments to VME driver APIMartyn Welch1-1/+11
Add kernel-doc comments to the VME driver API and structures. This documentation will be integrated into the RST documentation in a later patch. Signed-off-by: Martyn Welch <martyn.welch@collabora.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-01-11VME: Remove node entry from vme_driverMartyn Welch1-1/+0
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.

2016-12-06VME: Remove shutdown entry from vme_driverMartyn Welch1-1/+0
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. Signed-off-by: Martyn Welch <martyn.welch@collabora.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2016-08-31vme: change LM callback argument to void pointerAaron Sierra1-1/+1
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.

2013-12-03VME: Rename vme_slot_get to avoid confusion with reference countingMartyn Welch1-1/+1
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.

2013-12-03VME: Provide access to VME bus enumeration and fix vme_user match functionMartyn Welch1-0/+1
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.

2012-04-26Staging: VME: move VME drivers out of stagingGreg Kroah-Hartman1-0/+174
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.
