* hwmon: Replace SENSORS_LIMIT with clamp_valGuenter Roeck2013-01-261-13/+12
| | | | | | | | | | | | SENSORS_LIMIT and the generic clamp_val have the same functionality, and clamp_val is more efficient. This patch reduces text size by 9052 bytes and bss size by 11624 bytes for x86_64 builds.

* hwmon/f71882fg: Make the decision wether to register fan attr. per fanHans de Goede2011-10-241-65/+54
| | | | | | | | | | | | | | | Before this patch the f71882fg driver completely fails to initialize on systems which have reserved settings in the pwm enable register, and it disables all auto pwm sysfs attributes if any fan is controlled by a digital sensor reading. This patch changes the fail to initialize into don't register any attributes for the fan for which there are reserved settings in the pwm enable register and also makes the not registering of auto pwm sysfs attributes a per fan thing.

* hwmon/f71882fg: Add support for f71889edHans de Goede2011-03-151-11/+27
| | | | | | | | | | | | | | | | | | | | | | Note that this patch also makes 2 changes to the code paths for the f71889fg to keep the code unified between the 2 (for simplicities sake). Both of these are harmless for then f71889fg: 1) The first change is to always set the FAN_PROG_SEL bit to 0. This influences accesses to some banked fan / pwm registers. On the f71889fg no registers which we use are banked. On the f71889ed however some more fan registers have been banked including one which we use, by making the FAN_PROG_SEL bit 0, address 0x96 will point to the right register. 2) The second change is to see a FANx_TEMP_SEL value of 0 as pointing to a PECI / AMDSI value, and thus disable our pwm related sysfs attr. This is correct for the f71889ed and on the f71889fg 0 is a reserved value, so we should never see it and if we do, disabling the pwm related sysfs attr is a sane thing to do.

* hwmon: (f71882fg) Fix sysfs file removalHans de Goede2009-12-091-25/+66
| | | | | | | | | | | | | | There is a bug in the old sysfs file removal, as it uses fxxxx_in_temp_attr to remove the in and temp sysfs attributes, but fxxxx_in_temp_attr has temp#_alarm, where as f71858fg_in_temp_attr has temp#_max_alarm, so the temp#_max_alarm attributes for the f71858fg never get removed.

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.

| | | | | | | | | | This patch fixes a number of cases where things were not properly cleaned up when acpi_check_resource_conflict() returned an error, causing oopses such as the one reported here: https://bugzilla.redhat.com/show_bug.cgi?id=483208 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (f71882fg) Hide misleading error messageJean Delvare2009-02-171-1/+1
| | | | | | | | | | | | | If the F71882FG chip is at address 0x4e, then the probe at 0x2e will fail with the following message in the logs: f71882fg: Not a Fintek device This is misleading because there is a Fintek device, just at a different address. So I propose to degrade this message to a debug message. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Hans de Goede <hdegoede@redhat.com>
