2009-06-15hwmon: (f71882fg) Add temp#_fault sysfs attr for f8000Hans de Goede
While working on f71852fg support I noticed that the f8000 sysfs attr table was missing entries for temp#_fault, which the f8000 does have and which we were already reading. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2009-06-15hwmon: (f71882fg) Sanity check f8000 pwm settingsHans de Goede
We depend up on the pwm_enable register (0x96) not containing any reserved settings in various places. We were already checking to make sure there were no reserved settings in the register for the f71862fg, this patch adds the same checking for the f8000, while at it it also moves the code to a more apropriate place so we don't need to check if the fan/pwm part of the IC is enabled twice.

2009-06-15hwmon: (f71882fg) Cleanup f8000 pwm handlingHans de Goede
Currently we are using separate per model sysfs attr for the 3th pwm, because the 3th pwm of the f8000 only has automatic mode and not manual mode. Doing things this way was getting in the way for adding f71858fg support, so this patch makes the pwm attr identical for all models, and instead adds a check to store_pwm_enable() disallowing setting the 3th pwm to manual mode on a f8000 IC.

2009-06-15hwmon: PCI quirk for hwmon access on MSI MS-7031 boardJean Delvare
The MSI MS-7031 is based on an ATI IXP300 south bridge. On this south bridge, accessible I/O ports must be enabled explicitly. Unfortunately the BIOS forgets to enable access to the hardware monitoring chip I/O ports, so hardware monitoring fails. Add a quirk enabling access to the required ports (0x295-0x296). This is exactly what MSI's own hardware monitoring application is doing, so it has to be the right way. Signed-off-by: Jean Delvare <khali@linux-fr.org>
