vme: vme_get_size potentially returning incorrect value on failure

2016-10-28T12:25:18Z

The function vme_get_size returns the size of the window to the caller, however it doesn't check the return value of the call to vme_master_get. Return 0 on failure rather than anything else. Suggested-by: Dan Carpenter Signed-off-by: Martyn Welch Signed-off-by: Greg Kroah-Hartman

vme: fake: remove unexpected unlock in fake_master_set()

vme: fake: mark symbols static where possible

2016-09-27T10:43:34Z

We get 4 warnings when building kernel with W=1: drivers/vme/bridges/vme_fake.c:384:6: warning: no previous prototype for 'fake_lm_check' [-Wmissing-prototypes] drivers/vme/bridges/vme_fake.c:619:6: warning: no previous prototype for 'fake_vmewrite8' [-Wmissing-prototypes] drivers/vme/bridges/vme_fake.c:649:6: warning: no previous prototype for 'fake_vmewrite16' [-Wmissing-prototypes] drivers/vme/bridges/vme_fake.c:679:6: warning: no previous prototype for 'fake_vmewrite32' [-Wmissing-prototypes] In fact, these functions are only used in the file in which they are declared and don't need a declaration, but can be made static. so this patch marks these functions with 'static'.

vme: fake: fix build for 64-bit dma_addr_t

2016-09-13T15:30:17Z

casting between dma_addr_t and a pointer is generally tricky, as they might not be the same size and almost never point into the same address space. With 32-bit ARM systems and LPAE, we get this warning for the vme_fake driver that stores a pointer in a dma_addr_t variable: drivers/vme/bridges/vme_fake.c: In function 'fake_slave_set': drivers/vme/bridges/vme_fake.c:204:29: error: assignment makes pointer from integer without a cast [-Werror=int-conversion] To make this clearer while fixing the warning, I'm adding a set of helper functions for the type conversion.

vme: Adding Fake VME driver

2016-08-31T11:21:12Z

This patch introduces a fake VME bridge driver. This driver currently emulates a subset of the VME bridge functionality. This allows some VME subsystem development and even some VME device driver development to be carried out in the absence of a proper VME bus.

vme: make core vme support explicitly non-modular

2016-08-31T11:20:16Z

The Kconfig currently controlling compilation of this code is: drivers/vme/Kconfig:menuconfig VME_BUS drivers/vme/Kconfig: bool "VME bridge support" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We replace module.h and moduleparam.h (unused) with init.h and also export.h ; the latter since this file does export some syms. Since this is a struct bus_type and not a platform_driver, we don't have any ".suppress_bind_attrs" to be concerned about when we drop the ".remove" code from this file. Since module_init was not in use by this code, the init ordering remains unchanged with this commit.

vme: Fix module autoload

2016-08-31T11:20:16Z

These drivers have a PCI device ID table but the PCI module alias information is not created so module autoloading won't work. Signed-off-by: Alessio Igor Bogani Acked-by: Martyn Welch Signed-off-by: Greg Kroah-Hartman

vme: change LM callback argument to void pointer

2016-08-31T11:20:15Z

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. Signed-off-by: Aaron Sierra Acked-by: Martyn Welch Signed-off-by: Greg Kroah-Hartman

vme: add vme_init_bridge for common bridge init

2016-05-01T21:00:00Z

Consolidate vme_bridge structure setup that every bridge was required to do itself. This came about because .irq_mtx is only used within the VME core, but was required to be setup externally. This returns the structure passed in to support shorthand like this: bridge = vme_init_bridge(&priv->bridge); Signed-off-by: Aaron Sierra Acked-by: Martyn Welch Signed-off-by: Greg Kroah-Hartman
