[POWERPC] Fix drivers/macintosh/mediabay.c when !CONFIG_ADB_PMU

2008-03-12T23:09:27+00:00

When building drivers/macintosh/mediabay.c if CONFIG_ADB_PMU isn't
defined we get:

drivers/built-in.o: In function `media_bay_step':
mediabay.c:(.text+0x92b84): undefined reference to `pmu_suspend'
mediabay.c:(.text+0x92c08): undefined reference to `pmu_resume'

Create empty place holders in that scenario.

[POWERPC] Fix undefined pmu_sys_suspended compilation error

2008-03-12T23:09:27+00:00

pmu_sys_suspended is declared extern when:
	defined(CONFIG_PM_SLEEP) && defined(CONFIG_PPC32)
but only defined when:
	defined(CONFIG_SUSPEND) && defined(CONFIG_PPC32)
which is wrong.  Let's fix that.

[POWERPC] Fix for via-pmu based backlight control

2007-12-21T11:14:07+00:00

This fixes a few issues with via-pmu based backlight control.

First, it fixes a sign problem with the setup of the backlight
curve since the `range' value there -can- (and will) go negative.

Then, it reworks the interaction between this and the via-pmu sleep
code to properly restore backlight on wakeup from sleep.

[POWERPC] via-pmu: Kill sleep notifiers completely

2007-12-19T04:00:59+00:00

This kills off the remnants of the old sleep notifiers now that they
are no longer used.

[POWERPC] Fix undefined reference to device_power_up/resume

2007-08-25T06:58:27+00:00

Current Linus tree fails to link on pmac32:

drivers/built-in.o: In function `pmac_wakeup_devices':
via-pmu.c:(.text+0x5bab4): undefined reference to `device_power_up'
via-pmu.c:(.text+0x5bb08): undefined reference to `device_resume'
drivers/built-in.o: In function `pmac_suspend_devices':
via-pmu.c:(.text+0x5c260): undefined reference to `device_power_down'
via-pmu.c:(.text+0x5c27c): undefined reference to `device_resume'
make[1]: *** [.tmp_vmlinux1] Error 1

changing CONFIG_PM > CONFIG_PM_SLEEP leads to:

drivers/built-in.o: In function `pmu_led_set':
via-pmu-led.c:(.text+0x5cdca): undefined reference to `pmu_sys_suspended'
via-pmu-led.c:(.text+0x5cdce): undefined reference to `pmu_sys_suspended'
drivers/built-in.o: In function `pmu_req_done':
via-pmu-led.c:(.text+0x5ce3e): undefined reference to `pmu_sys_suspended'
via-pmu-led.c:(.text+0x5ce42): undefined reference to `pmu_sys_suspended'
drivers/built-in.o: In function `adb_init':
(.init.text+0x4c5c): undefined reference to `pmu_register_sleep_notifier'
make[1]: *** [.tmp_vmlinux1] Error 1

So change even more places from PM to PM_SLEEP to allow linking.

[POWERPC] pmu_sys_suspended is only defined for PPC32

2007-05-10T11:28:13+00:00

thus we get a link error on ppc64 with CONFIG_PM=y.  This fixes it.

[POWERPC] via-pmu: remove LED sleep notifier

2007-05-08T01:54:19+00:00

The generic LED code now makes sure that suspended devices don't blink,
so we no longer need to do it ourselves. For the suspend to disk case,
however, we need to make sure that we don't blink if the PMU sysdev
was suspended before the LED device.

[POWERPC] powermac: disallow pmu sleep notifiers from aborting sleep

2007-03-26T02:35:17+00:00

Tracing through the code, no current PMU sleep notifier can abort sleep.
Since no new PMU sleep notifiers should be added, this patch simplifies the
code and removes the ability to abort sleep.

[PATCH] powermac: More powermac backlight fixes

2006-07-31T20:28:45+00:00

This patch fixes several problems:
- The legacy backlight value might be set at interrupt time. Introduced
  a worker to prevent it from directly calling the backlight code.
- via-pmu allows the backlight to be grabbed, in which case we need to
  prevent other kernel code from changing the brightness.
- Don't send PMU requests in via-pmu-backlight when the machine is about
  to sleep or waking up.
- More Kconfig fixes.

[PATCH] Rewritten backlight infrastructure for portable Apple computers

2006-06-25T17:00:59+00:00

This patch contains a total rewrite of the backlight infrastructure for
portable Apple computers.  Backward compatibility is retained.  A sysfs
interface allows userland to control the brightness with more steps than
before.  Userland is allowed to upload a brightness curve for different
monitors, similar to Mac OS X.
