2007-12-06[POWERPC] Clean out asm/of_{platform, device}.h from sysdev/Jon Loeliger
Convert #include of asm/of_{platform, device}.h into linux/of_{platform,device}.h for remaining arch/powerpc files. Signed-off-by: Jon Loeliger <jdl@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-10-11[POWERPC] Move of_platform_driver initialisations: arch/powerpcStephen Rothwell
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. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Acked-by: Olof Johansson <olof@lixom.net> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-07-20[CELL] pmi: remove support for mutiple devices.Christian Krafft
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.

2007-04-23[POWERPC] add of_iomap functionChristian Krafft
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. Signed-off-by: Christian Krafft <krafft@de.ibm.com> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
2007-04-23[POWERPC] pmi probe device by device-typeChristian Krafft
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.

2007-04-23[POWERPC] add check for initialized driver data to pmi driverChristian Krafft
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.

2007-02-16[POWERPC] Add PMI driver for cell bladeChristian Krafft
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.
