powerpc/therm_adt746x: Record pwm invert bit at module load time]

2009-12-18T21:44:24+00:00

commit 1496e89ae2a0962748e55165a590fa3209c6f158 upstream. In commit 0512a9a8e277a9de2820211eef964473b714ae65, we unilaterally zero the "pwm invert" bit in the fan behavior configuration register. On my PowerBook G4, this results in the fans going to full speed at low temperature and shutting off at high temperature because the pwm invert bit is supposed to be set. Therefore, record the pwm invert bit at driver load time, and write the bit into the fan behavior control register. This restores correct behavior on my PBG4 and should work around the bit being set to the wrong value after suspend/resume (which is what the original patch was trying to fix). It also fixes a minor omission where the pwm invert bit correction is NOT performed when switching into automatic mode. Signed-off-by: Darrick J.

powerpc/pmac: Fix issues with sleep on some powerbooks

2009-11-10T00:23:12+00:00

commit 11a50873ef2b3c1c3fe99a661c22c08f35d93553 upstream. Since the change of how interrupts are disabled during suspend, certain PowerBook models started exhibiting various issues during suspend or resume from sleep. I finally tracked it down to the code that runs various "platform" functions (kind of little scripts extracted from the device-tree), which uses our i2c and PMU drivers expecting interrutps to work, and at a time where with the new scheme, they have been disabled. This causes timeouts internally which for some reason results in the PMU being unable to see the trackpad, among other issues, really it depends on the machine. Most of the time, we fail to properly adjust some clocks for suspend/resume so the results are not always predictable. This patch fixes it by using IRQF_TIMER for both the PMU and the I2C interrupts. I prefer doing it this way than moving the call sites since I really want those platform functions to still be called after all drivers (and before sysdevs). We also do a slight cleanup to via-pmu.c driver to make sure the ADB autopoll mask is handled correctly when doing bus resets Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Greg Kroah-Hartman

macintosh: Don't assume i2c device probing always succeeds

2009-10-22T22:11:58+00:00

commit 6f6b35e133fe4313277b30fc1a7ea313875ea6c9 upstream. If i2c device probing fails, then there is no driver to dereference after calling i2c_new_device(). Stop assuming that probing will always succeed, to avoid NULL pointer dereferences. We have an easier access to the driver anyway.

powerpc/pmac: Fix DMA ops for MacIO devices

2009-06-26T04:37:25+00:00

The macio_dev's created to map devices inside the MacIO ASICs don't have proper dma_ops. This causes crashes on some machines since the SCSI code calls dma_map_* on our behalf using the device we hang from. This fixes it by copying the parent PCI device dma_ops into the macio_dev when creating it. Signed-off-by: Benjamin Herrenschmidt

The legacy i2c binding model is going away soon, so convert the macintosh therm_pm72 driver to the new model or it will break. This is really a quick and dirty conversion, that should do the trick for now, but no doubt that something cleaner can be done if anyone is interested.
