This converts the therm_pm72.c driver to use the kthread API. I
thought about making it use kthread_stop() instead of the `state'
variable and the `ctrl_complete' completion, but that isn't simple and
will require changing the way that `state' is used.Signed-off-by: Paul Mackerras

This patch first splits of_device.c and of_platform.c, the later containing
the bits relative to of_platform_device's. On the "breaks" side of things,
drivers uisng of_platform_device(s) need to include asm/of_platform.h now
and of_(un)register_driver is now of_(un)register_platform_driver.In addition to a few utility functions to locate of_platform_device(s),
the main new addition is of_platform_bus_probe() which allows the platform
code to trigger an automatic creation of of_platform_devices for a whole
tree of devices.The function acts based on the type of the various "parent" devices encountered
from a provided root, using either a default known list of bus types that can be
"probed" or a passed-in list. It will only register devices on busses matching
that list, which mean that typically, it will not register PCI devices, as
expected (since they will be picked up by the PCI layer).This will be used by Cell platforms using 4xx-type IOs in the Axon bridge
and can be used by any embedded-type device as well.Signed-off-by: Benjamin Herrenschmidt

The thermal control for the Xserve G5s had a few issues. For one, the
way to program the RPM fans speeds into the FCU is different between it
and the desktop models, which I didn't figure out until recently, and it
was missing a control loop for the slots fan, running it too fast. Both
of those problems were causing the machine to be much more noisy than
necessary. This patch also changes the fixed value of the slots fan for
desktop G5s to 40% instead of 50%. It seems to still have a pretty good
airflow that way and is much less noisy.Signed-off-by: Benjamin Herrenschmidt

Now that i2c_add_driver() doesn't need the module owner to be set by
hand, we can delete it from the drivers. This patch catches all of the
drivers that I found in the current tree (if a driver sets the .owner by
hand, it's not a problem, just not needed.)Signed-off-by: Greg Kroah-Hartman

Just about every i2c chip driver sets the I2C_DF_NOTIFY flag, so we
can simply make it the default and drop the flag. If any driver really
doesn't want to be notified when i2c adapters are added, that driver
can simply omit to set .attach_adapter. This approach is also more
robust as it prevents accidental NULL pointer dereferences.Signed-off-by: Jean Delvare

Some G5s still occasionally experience shutdowns due to overtemp
conditions despite the recent fix. After analyzing logs from such
machines, it appears that the overtemp code is a bit too quick at
shutting the machine down when reaching the critical temperature (tmax +
8) and doesn't leave the fan enough time to actually cool it down. This
happens if the temperature of a CPU suddenly rises too high in a very
short period of time, or occasionally on boot (that is the CPUs are
already overtemp by the time the driver loads).This patches makes the code a bit more relaxed, leaving a few seconds to
the fans to do their job before kicking the machine shutown.Signed-off-by: Benjamin Herrenschmidt

The g5 thermal control for liquid cooled machines has a small bug, when
the temperatures gets too high, it boosts all fans to the max, but
incorrectly sets the liquids pump to the min instead of the max speed,
thus causing the overtemp condition not to clear and the machine to shut
down after a while. This fixes it to set the pumps to max speed instead.
This problem might explain some of the reports of random shutdowns that
some g5 users have been reporting in the past.Many thanks to Marcus Rothe for spending a lot of time trying various
patches & sending log logs before I found out that typo. Note that
overtemp handling is still not perfect and the machine might still
shutdown, that patch should reduce if not eliminate such occcurences in
"normal" conditions with high load. I'll implement a better handling
with proper slowing down of the CPUs later.Signed-off-by: Benjamin Herrenschmidt

The SMU is the "system controller" chip used by Apple recent G5 machines
including the iMac G5. It drives things like fans, i2c busses, real time
clock, etc...The current kernel contains a very crude driver that doesn't do much more
than reading the real time clock synchronously. This is a completely
rewritten driver that provides interrupt based command queuing, a userland
interface, and an i2c/smbus driver for accessing the devices hanging off
the SMU i2c busses like temperature sensors. This driver is a basic block
for upcoming work on thermal control for those machines, among others.Signed-off-by: Benjamin Herrenschmidt

This converts the usage of struct of_match to struct of_device_id,
similar to pci_device_id. This allows a device table to be generated,
which can be parsed by depmod(8) to generate a map file for module
loading.In order for hotplug to work with macio devices, patches to
module-init-tools and hotplug must be applied. Those patches are
available at:ftp://ftp.suse.com/pub/people/jeffm/linux/macio-hotplug/

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
