Stephen Rothwell 84dd4676f5 [POWERPC] Move of_platform_driver initialisations: arch/powerpc
We no longer initialise the name and owner fields of the
of_platform_driver, but use the fields of the embedded device_driver's
name field instead.

Christian Krafft 813f90728e [CELL] pmi: remove support for mutiple devices.
The pmi driver got simplified by removing support for multiple devices.
As there is no more than one pmi device per maschine, there is no need to
specify the device for listening and sending messages.

This way the caller (cbe_cpufreq) doesn't need to scan the device tree.
When registering the handler on a board without a pmi
interface, pmi.c will just return -ENODEV.

The patch that fixed the breakage of cell_defconfig has been
broken out of the earlier version of this patch. So this is
the version that applies cleanly on top of it.

Christian Krafft 6bf05fd776 [POWERPC] add of_iomap function
The of_iomap function maps memory for a given
device_node and returns a pointer to that memory.
This is used at some places, so it makes sense to
a seperate function.

Christian Krafft 4a065f9418 [POWERPC] pmi probe device by device-type
At the moment the pmi device driver is probing for devices with
a given type and a given name. As there may be devices of
the same type but with a different name, probing should be
done also for device type only.

Christian Krafft 79baf4a60e [POWERPC] add check for initialized driver data to pmi driver
This patch adds a check for the private driver data to be initialized.
The bug showed up, as the caller found a pmi device by it's type.
Whereas the pmi driver probes for the type and the name.
Since the name was not as the driver expected, it did not initialize.
A more relaxed probing will be supplied with an extra patch, too.

Christian Krafft 0e8266437c [POWERPC] Add PMI driver for cell blade
This adds driver code for the PMI device found in future IBM products.
PMI stands for "Platform Management Interrupt" and is a way to
communicate with the BMC (Baseboard Management Controller).
It provides bidirectional communication with a low latency.
