* PCI: Remove includes of asm/pci-bridge.hBjorn Helgaas2016-02-051-1/+0
| | | | | | | | | | | Drivers should include asm/pci-bridge.h only when they need the arch- specific things provided there. Outside of the arch/ directories, the only drivers that actually need things provided by asm/pci-bridge.h are the powerpc RPA hotplug drivers in drivers/pci/hotplug/rpa*. Remove the includes of asm/pci-bridge.h from the other drivers, adding an include of linux/pci.h if necessary. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

| * macintosh/therm_windtunnel: Export OF module alias informationJavier Martinez Canillas2015-08-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So technically there's no need for a driver to export the OF table since currently it's not used. In fact, the I2C device ID table is mandatory for I2C drivers since a i2c_device_id is passed to the driver's probe function even if the I2C core used the OF table to match the driver. And since the I2C core uses different tables, OF-only drivers needs to have duplicated data that has to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. To avoid the above, the I2C core behavior may be changed in the future to not require an I2C device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table to prevent breaking module autoloading if that happens.

| * powerpc: Move Power Macintosh drivers to generic byteswappersDavid Gibson2015-03-231-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ppc has special instruction forms to efficiently load and store values in non-native endianness. These can be accessed via the arch-specific {ld,st}_le{16,32}() inlines in arch/powerpc/include/asm/swab.h. However, gcc is perfectly capable of generating the byte-reversing load/store instructions when using the normal, generic cpu_to_le*() and le*_to_cpu() functions eaning the arch-specific functions don't have much point. Worse the "le" in the names of the arch specific functions is now misleading, because they always generate byte-reversing forms, but some ppc machines can now run a little-endian kernel. To start getting rid of the arch-specific forms, this patch removes them from all the old Power Macintosh drivers, replacing them with the generic byteswappers.

* powerpc/windfarm: Fix noisy slots-fan on Xserve (rm31)Aaro Koskinen2013-08-011-9/+9
| | | | | | | | | | | | | | slots-fan on G5 Xserve is always running at full speed with windfarm_rm31 driver, resulting in a very high acoustic noise level. It seems the fan parameters are incorrect, and have been copied from the Drive Bay fan (RPM, not present on rm31) of the legacy therm_pm72 driver. This patch changes the parameters to match the Slots fan (PWM) of therm_pm72. With the patch, slots-fan speed drops from 99% to 19% during normal use, and slots-temp settle to ~42'C.

* powerpc/windfarm: Fix overtemperature clearingAaro Koskinen2013-07-013-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With pm81/pm91/pm121, when the overtemperature state is entered, and when it remains on after skipped ticks, the driver will try to leave it too soon (immediately on the next tick). This is because the active FAILURE_OVERTEMP state is not visible in "new_failure" variable of the current tick. Furthermore, the driver will keep trying to clear condition in subsequent ticks as FAILURE_OVERTEMP remains set in the "last_failure" variable. These will start to trigger WARNINGS from windfarm core: [ 100.082735] windfarm: Clamping CPU frequency to minimum ! [ 100.108132] windfarm: Overtemp condition detected ! [ 101.952908] windfarm: Overtemp condition cleared !
