ad3c0fe8b8 firewire: debug interrupt events
This adds debug printks for asynchronous transmission and reception and
for self ID reception.  They can be enabled at module load time, and at
runtime via /sys/module/firewire_ohci/parameters/debug.

Signed-off-by: Jarod Wilson <jwilson@redhat.com>

Also added:  Logging of interrupt event codes and of cancelled AT
packets.

The code now depends on a Kconfig variable.  This makes it easier to
build firewire-ohci without the feature or to make it an option in the
future.  The variable is currently hidden and always on.

This feature inflates firewire-ohci.ko by 7 kB = 27% on x86-64 and by
4 kB = 23% on i686.

016bf3dfcf firewire: fw-ohci: catch self_id_count == 0
fw_core_handle_bus_reset() incorrectly relied on the assumption that
self_id_count > 0.

We check early in fw-ohci and discard the self ID complete event if
self_id_count == 0 because a valid event always has at least one self ID
packet in it (the one of the local node).  Hence treat self_id_count ==
0 like any other kind of invalid self ID buffer.

eb5ca72eff firewire: fw-ohci: switch on bus power after resume on PPC PMac
The platform feature calls in the suspend method switched off cable
power, but the calls in the resume method did not switch it back on.

Add the necessary feature call to .resume.  Also add the corresponding
call to .suspend to make .suspend's behavior explicitly the same on all
PMacs.

17cff9ff87 firewire: fw-sbp2: set dual-phase cycle_limit
Try to write dual-phase retry protocol limits to BUSY_TIMEOUT register.
- The dual-phase retry protocol is optional to implement, and if not 
  supported, writes to the dual-phase portion of the register will be
  ignored. We try to write the original 1394-1995 default here.
- In the case of devices that are also SBP-3-compliant, all writes are 
  ignored, as the register is read-only, but contains single-phase retry of
  15, which is what we're trying to set for all SBP-2 device anyway, so this
  write attempt is safe and yields more consistent behavior for all devices.

See section 8.3.2.3.5 of the 1394-1995 spec, section 6.2 of the SBP-2 spec,
and section 6.4 of the SBP-3 spec for further details.

It should actually suffice to do this only for the local node's

The local node's speed is not correctly propagated to the speeds
which are to be used to access remote nodes.

d2ace29fa4 ieee1394: prevent device binding of raw1394, video1394, dv1394
These drivers don't need to match any unit_directory type device.
They just need the id_table for module autoloading per module alias.

Not binding any of these drivers allows special-purpose drivers with
similar or same IDs to bind to devices.  This currently only benefits
out-of-tree drivers; on the other hand it is in no way detrimental to
in-tree drivers.

      Author: Muli Ben-Yehuda <muli@il.ibm.com>
      Date:   Sun Jul 22 00:23:39 2007 +0300

         x86-64: introduce struct pci_sysdata to facilitate sharing of ->sysdata

         This patch introduces struct pci_sysdata to x86 and x86-64, and
         converts the existing two users (NUMA, Calgary) to use it.

         This lays the groundwork for having other users of sysdata, such as
         the PCI domains work.

         The Calgary bits are tested, the NUMA bits just look ok.

replaces pcibios_scan_root by pci_scan_bus_parented...

but in pcibios_scan_root we have a check about scanned busses.

4bb5eba06b spi: spi_s3c24xx driver must init completion
The s3c24xx_spi_txrx() function should initialise the completion each time
before using it, otherwise we end up with the possibility of returning success
before the interrupt handler has processed all the data.
