vme: tsi148: Master windows support USERx and CR/CSR accesses, not slaves

2015-03-07T01:03:22+00:00

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.

staging: vme: mmap() support for vme_user

2015-03-07T01:03:22+00:00

We also make sure that user won't be able to reconfigure the window while it is
mmap'ed.

vme: fix misspelling of current function in string

2015-01-12T13:04:12+00:00

Replace a misspelled function name by %s and then __func__.

This is the get function, not the set function, as was indicated by the
string.

This was done using Coccinelle, including the use of Levenshtein distance,
as proposed by Rasmus Villemoes.

VME: remove duplicate CA91CX42_DCTL_VDW_M define

The CA91CX42_DCTL_VDW_M define is cut and pasted twice so we can delete
the second instance.

vme_tsi148: Fix PCI address mapping assumption

2014-04-16T21:08:37+00:00

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.

vme_tsi148: Fix typo in tsi148_slave_get()

2014-04-16T21:08:37+00:00

This patch corrects a typo where "vme_base" was used instead of
"*vme_base". The typo resulted in an incorrect value being returned
to userspace (via vme_user).

It also removes the following compile warning on some platforms:

warning: cast from pointer to integer of different size

VME: Stop using memcpy_[to|from]io() due to unwanted behaviour

2014-02-15T19:53:39+00:00

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.
