be9b614d12 Clear the backlight level when it's turned off. Also, reduce the delay times to
less conservative values, also found in the radeonkms driver.

7b92a9bfc4 Fix the ATI backlight driver off/on handling. Now this driver works correctly
with the ATI Radeon 9700 in the PowerBook G4 1.67GHz.

Code shamelessly taken in spirit from the radeonkms driver, which I hope will
make this driver redundant in the future.

65d08437ef Move Open Firmware device root on PowerPC, ARM, and MIPS systems to
a sub-node of nexus (ofwbus) rather than direct attach under nexus. This
fixes FDT on x86 and will make coexistence with ACPI on ARM systems easier.
SPARC is unchanged.

d25b22e12b Fix the resource information for the i2s-a node on certain G5 PowerMacs.
This is the first step needed to get the snapper codec working on those
machines.
The second step is to enable the corresponding I2S device and its clock.

Tested on machines where the snapper codec was already working, a G4 PowerBook
and a PowerMac9,1 with a Shasta based macio.
The PowerMac7,2/7,3 with a K2 based macio can now also play sound.

c63e7b9304 Add suspend/resume handlers for ATI backlight ppc driver.
With this, also shut shut off the display (DPMS-style) and disable the clocking
when the backlight level is set to 0.  This is taken from the radeonkms driver
(radeon_legacy_encoders.c) which doesn't yet support PowerPC, and won't for a
while, as it's missing full AGP support.

c1cb22d755 Rearchitect platform memory map parsing to make it less
Open Firmware-centric:
- Keep the static list of regions in platform.c instead of ofw_machdep.c
- Move various merging and sorting operations to platform.c as well
- Move apple_hacks code out of ofw_machdep.c and into platform_powermac.c,
  where it belongs
- Move CHRP-specific dynamic-reconfiguration memory parsing into
  platform_chrp.c instead of pretending it is shared code

7a22215c53 Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit.  Instead use (1U << 31) which gets the
expected result.

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

4ee635532e Use #address-cells and #size-cells here too instead of guessing. There is
some comment I wrote about these values "lying" in the negative diff, which
referes to an earlier misunderstanding about which node to read them from.
This gets at least the PPC64 kernel booting in the mac99 system model in
QEMU after bypassing the MacIO ATA driver, which apparently still has

17593f8612 Standards-conformance and code deduplication:
- Use bus reference phandles in place of FDT offsets as IRQ domain keys
- Unify the identical macio/fdt/mambo OpenPIC drivers into one
- Be more forgiving (following ePAPR) about what we need from the device
  tree to identify an OpenPIC
- Correctly map all IRQs into an interrupt domain
- Set IRQ_*_CONFORM for interrupts on an unknown PIC type instead of
  failing attachment for that device.

965205eb66 Move the resource allocation from the ata_*_probe section to the ata_*_attach
section. This prevents a boot crash on nearly all iMacs and PowerMacs/Books.

The allocation in the probe section was working before because ata_probe was
returning 0 which did not invoke a second DEVICE_PROBE. Now it returns
a BUS_PROBE_DEFAULT which can invoke a second DEVICE_PROBE which results in
a "failed to reserve resource" exit.

9f70672718 Rework handling of ofw_quiesce(), making it the responsibility of the
platform modules. Whether to call this function or not is highly machine
dependent: on some systems, it is required, while on others it breaks
everything. Platform modules are in a better position to figure this
out. This is required for POWER hypervisor SCSI to work correctly. There
are no functional changes on Powermac systems.

0cb9915474 Add support for PWM controlled fans. I found these fans on my PowerMac9,1.
These fans are not located under the same node as the the RPM controlled ones,
So I had to adapt the current source to parse and fill the properties correctly.
To control the fans we can set the PWM ratio via sysctl between 20 and 100%.

07042bef45 Fix OF_finddevice error return value in case of FDT.
According to the open firmware standard, finddevice call has to return
a phandle with value of -1 in case of error.

This commit is to:
- Fix the FDT implementation of this interface (ofw_fdt_finddevice) to
  return (phandle_t)-1 in case of error, instead of 0 as it does now.
- Fix up the callers of OF_finddevice() to compare the return value with
  -1 instead of 0 to check for errors.
- Since phandle_t is unsigned, the return value of OF_finddevice should
  be checked with '== -1' rather than '<= 0' or '> 0', fix up these cases
  as well.
