2016-10-21vme: Convert documentation to reStructuredText, move under driver APIsMartyn Welch
Perform a relatively simple conversion of vme_api.txt to reStructuredText and move under driver-api, which seems the most logical place for this documentation. Signed-off-by: Martyn Welch <martyn.welch@collabora.co.uk> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2016-08-31vme: Update documentation to match apiMartyn Welch
The vme_register_driver() api changed in commit 5d6abf379d73 ("staging: vme: make match() driver specific to improve non-VME64x support") but the documentation wasn't updated. Update the documentation to match the API. Signed-off-by: Martyn Welch <martyn@welchs.me.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2016-08-31vme: change LM callback argument to void pointerAaron Sierra
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 Welch
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 Welch
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.
