powerpc/fsl_msi: add support for "msi-address-64" property

2011-10-14T07:54:29+00:00

Add support for the msi-address-64 property of a PCI node.  This property
specifies the PCI address of MSIIR (message signaled interrupt index
register).

In commit 3da34aae ("powerpc/fsl: Support unique MSI addresses per PCIe Root
Complex"), the msi_addr_hi/msi_addr_lo fields of struct fsl_msi were redefined
from an actual address to just an offset, but the fields were not renamed
accordingly.  These fields are replace with a single field, msiir_offset,
to reflect the new meaning.

powerpc/fsl_msi: fix support for multiple MSI ranges

2011-10-11T21:18:55+00:00

Commit 6820fead ("powerpc/fsl_msi: Handle msi-available-ranges better") added
support for multiple ranges in the msi-available-ranges property, but it
miscalculated the MSIR index when multiple ranges are used.

treewide: Convert uses of struct resource to resource_size(ptr)

2011-06-10T12:55:36+00:00

Several fixes as well where the +1 was missing.

Done via coccinelle scripts like:

@@
struct resource *ptr;
@@

- ptr->end - ptr->start + 1
+ resource_size(ptr)

and some grep and typing.

Mostly uncompiled, no cross-compilers.

powerpc/fsl_msi: Use chip_data not handler_data

2011-05-19T05:31:45+00:00

handler_data should be reserved for flow handlers on the dependent
irq, not consumed by the parent irq code that is part of the irq_chip
code.  The msi_data pointer was already set in msidesc->irqhost->hostdata
and being copied to irq_data->chipdata in the msidesc->irqhost->map()
method called via create_irq_mapping, so we can obtain the pointer
from there and free the instance it in teardown_msi_irqs.

Also remove the unnecessary cast of irq_get_handler_data in the
cascade handler, which is the demux flow handler of the parent
msi interrupt.  (This is the expected usage for handler_data).

powerpc/fsl_msi: Don't abuse platform_data for driver_data

2011-05-19T05:31:43+00:00

The msi platform device driver was abusing dev.platform_data for its
platform_driver_data.  Use the correct pointer for storage.

Platform_data is supposed to be for platforms to communicate to drivers
parameters that are not otherwise discoverable.  Its lifetime matches
the platform_device not the platform device driver.  It is generally
not needed for drivers that only support systems with device trees.

drivercore: revert addition of of_match to struct device

2011-05-18T18:32:23+00:00

Commit b826291c, "drivercore/dt: add a match table pointer to struct
device" added an of_match pointer to struct device to cache the
of_match_table entry discovered at driver match time.  This was unsafe
because matching is not an atomic operation with probing a driver.  If
two or more drivers are attempted to be matched to a driver at the
same time, then the cached matching entry pointer could get
overwritten.

This patch reverts the of_match cache pointer and reworks all users to
call of_match_device() directly instead.
