2009-12-11staging: vme: Fix mutex lockingMartyn Welch
Fix incorrect use of mutex_trylock(). Signed-off-by: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11Staging: vme: Rename VME DMA functionsMartyn Welch
The DMA resource allocation function is called "vme_request_dma" while master and slave window allocation functions are called "vme_master_request" and "vme_slave_request" respectively. Rename "vme_request_dma" to "vme_dma_request" to fit the pattern. Signed-off-by: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11Staging: vme: Clean up tsi148 driverMartyn Welch
* Remove message from IACK interrupt handler * Correct clearing of location monitor interrupts * Remove interrupt cleanup code that's duplcated in sub function Signed-off-by: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11Staging: vme: Correct operation of vme_lm_freeMartyn Welch
The vme_lm_free() function is not clearing up the resource created in vme_lm_request(). In addition vme_lm_free() is void function and is used in exit/error paths, we should wait for mutex to become free rather than exiting and not freeing the resource.

2009-12-11Staging: vme: Allow size of 0 when disabling a windowMartyn Welch
The TSI148 driver currently does not allow a size of zero to be passed to a window. Zero is a valid value if the window is being disabled. Allow windows to be disabled and their registers cleared. Signed-off-by: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11Staging: vme: fix compiler warnings in vme_ca91cx42.cGreg Kroah-Hartman
It's causing people to ignore problems in the file, so get rid of them so it's obvious something is wrong in the future. Cc: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11Staging: vme: Pull common VME interrupt handling into core codeMartyn Welch
Currently the VME callback infrastructure is replicated in each VME driver. Move this common code into the VME core. Rename functions to fit in better with naming of other VME functions. Signed-off-by: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11staging: vme: correct array overflowMartyn Welch
Eric Sesterhenn noticed that vme_user is overflowing an array used by sprintf. Use a bigger array. CC: Eric Sesterhenn <eric.sesterhenn@lsexperts.de> Signed-off-by: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-12-11Staging: vme: remove unused #include <linux/version.h>Huang Weiyi
Remove unused #include <linux/version.h>('s) in drivers/staging/vme/bridges/vme_ca91cx42.c drivers/staging/vme/bridges/vme_tsi148.c drivers/staging/vme/devices/vme_user.c drivers/staging/vme/vme.c Signed-off-by: Huang Weiyi <weiyi.huang@gmail.com> Acked-by: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-10-14Staging: vme: fix sched.h build breakageGreg Kroah-Hartman
commit d43c36dc removed sched.h from interrupt.h. This broke the vme drivers. This patch fixes them. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-09-15Staging: vme: change to VME_BUSGreg Kroah-Hartman
Turns out the m68k arch already has a CONFIG_VME, so use CONFIG_VME_BUS instead. Thanks to Geet Uytterhoeven for pointing this out. Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-09-15Staging: vme: Separate the list of TODOs from the API documentationMartyn Welch
This patch moves the API documentation to it's own file and provides a proper list of TODOs. Signed-off-by: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-09-15Staging: vme: Update support for the Universe II VME driverMartyn Welch
This patch starts the reworking of the vme_ca91cx42.c for the VME core. The driver seems to have only supported the Universe II for a long time, I have no hardware to check to see if it would work on the Universe I. This patch is compile tested with minimal run-time testing. It enables basic support for slave and master windows and interrupts. The master windows have undergone basic run testing.

2009-09-15Staging: vme: add VME Location Monitor management mechanismMartyn Welch
Extend the image and DMA channel resource management methods to control the location monitor resource. The location monitor should be controlled as it can only be used at a single location at a time. Signed-off-by: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-09-15Staging: Use proper mutexes in the tsi-148 VME driverMartyn Welch
The VME core and tsi-148 driver currently use semaphores as mutexes. Switch to proper mutex implementation. Signed-off-by: Martyn Welch <martyn.welch@gefanuc.com> Reviewed-by: Emilio G. Cota <cota@braap.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-09-15Staging: Update VME vme_user moduleMartyn Welch
* Add ifdef wrapper to vme_user.h * Correct Initialisation routine * Add remove routine to correct probe routine * Remove old test routines Signed-off-by: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-09-15Staging: vme: Add syncronize interrupts before removing callbackMartyn Welch
As identified by Jiri, there is no syncronisation before callback is removed. Signed-off-by: Martyn Welch <martyn.welch@gefanuc.com> Cc: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-09-15Staging: vme: Extend VME core probing for special matchesMartyn Welch
Add the ability to define all slots and current slot in the VME buses bind table. Signed-off-by: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-09-15Staging: vme: Correct tsi-148 VME interrupt free routineMartyn Welch
As identified by Jiri, the VME interrupt free routine removes the service routine before disabling the interrupt. Re-order operations to be performed in the reverse of the request routine.

2009-09-15Staging: vme: add Universe I/II bridge driverMartyn Welch
Currently this code doesn't compile, so it is disabled. That should be fixed up... Signed-off-by: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-09-15Staging: VME Framework for the Linux KernelMartyn Welch
This framework aims to colelese, extend and improve the VME Linux drivers found at vmelinux.org, universe2.sourceforge.net and openfmi.net/frs/?group_id=144. The last 2 drivers appear to be forks of the original code found at vmelinux.org though have extended the codebase.
