2015-03-07vme: tsi148: Master windows support USERx and CR/CSR accesses, not slavesMartyn Welch1-8/+3
The tsi148 driver is registering the slave images as supporting the "USER" access modes and CR/CSR access mode rather than the master images as it should. Remove the incorrect case entries for these modes from the tsi148_slave_set() function, stop registering slave_images as supporting these modes and instead register master windows as supporting these modes.

2014-04-17vme_tsi148: Fix PCI address mapping assumptionJoe Schultz1-1/+7
Previously, tsi148_master_set() assumed the address contained in its PCI bus resource represented the actual PCI bus address. This is a fine assumption on some platforms. However, on platforms that don't use a 1:1 (CPU:PCI) mapping this results in the tsi148 driver configuring an invalid master window translation. This patch updates the vme_tsi148 driver to first convert the address contained in the PCI bus resource into a PCI bus address before using it.

2014-02-15VME: Stop using memcpy_[to|from]io() due to unwanted behaviourMartyn Welch2-24/+23
The ca91cx42 and tsi148 VME bridges use the width of reads and writes on the PCI bus in part to control the width of the cycles on the VME bus. It is important that we can control the width of cycles on the VME bus as some VME hardware requires cycles of a specific width. The memcpy_toio() and memcpy_fromio() functions do not provide sufficient control, so instead loop using ioread functions.

2014-02-07VME: Correct read/write alignment algorithmMartyn Welch2-4/+4
In order to ensure the correct width cycles on the VME bus, the VME bridge drivers implement an algorithm to utilise the largest possible width reads and writes whilst maintaining natural alignment constraints. The algorithm currently looks at the start address rather than the current read/write address when determining whether a 16-bit width cycle is required to get to 32-bit alignment. This results in incorrect alignment, Reported-by: Jim Strouth <james.strouth@ge.com> Tested-by: Jim Strouth <james.strouth@ge.com> Signed-off-by: Martyn Welch <martyn.welch@ge.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-12-18vme: Convert VME core to register as a subsystemAaron Sierra2-6/+2
Previously, VME bridge support was treated as any other driver (using module_init() macro), but if VME bridge and vme_user (staging) drivers were compiled into the kernel, then vme_user would attempt to register itself before the VME core support had been loaded. This would result in a kernel panic. The load order of these built-in drivers is based on the order in which drivers/staging/vme and driver/vme are compiled. This patch changes the VME core driver to use the subsys_initcall() macro which ensures that it is loaded before all other VME drivers regardless of the order in which they are compiled.

2013-12-03VME: Provide access to VME bus enumeration and fix vme_user match functionMartyn Welch1-0/+13
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.

Since we will be removing items off the list using list_del() we need to use a safer version of the list_for_each() macro aptly named list_for_each_safe(). Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-07-20VME: Prevent D16 cycles being split into 8-bit blocksMartyn Welch1-2/+83
The memcpy_fromio() and memcpy_toio() functions use the __memcpy() function, at least on x86. This function carries out transfers smaller than 32 bits as multiple 8 bit transfers, causing a single (aligned) 16 bit transfer to be split into 2 8 bit transfers which may not be supported by the target VME device. The commit 53059aa05988761a738fa8bc082bbf3c5d4462d1 fixed this for the ca91cx42, however this was not fixed for the tsi148 at the time. This patch uses the same algorithm to fix the tsi148.

2012-04-26Staging: VME: move VME drivers out of stagingGreg Kroah-Hartman15-0/+8947
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.
