2008-08-04powerpc: Move include files to arch/powerpc/include/asmStephen Rothwell
from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where <asm-powepc/...> was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-07-22powerpc/cell: Add support for power button of future IBM cell bladesChristian Krafft
This patch adds support for the power button on future IBM cell blades. It actually doesn't shut down the machine. Instead it exposes an input device /dev/input/event0 to userspace which sends KEY_POWER if power button has been pressed. haldaemon actually recognizes the button, so a plattform independent acpid replacement should handle it correctly.

2008-04-15[POWERPC] remove include of asm/of_device.h from pmi.hStephen Rothwell
pmi.h does not diectly reference anything in of_device.h and of the two files that include asm/pmi.h, one includes of_device.h and the other includes of_platform.h (which includes of_device.h). Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> 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.

2007-02-16[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.
