* hwmon: (lineage-pem): Fix in1 voltage alarm sysfs attributesGuenter Roeck2011-03-16
| | | | | | | | | | | | The alarm bit assumed to be a low voltage alarm bit is not set for low voltage alarms, and the alarm bit assumed to be a high voltage alarm turns out to be a general alarm bit which is set for both low and high voltage alarms. Remove the in1_min_alarm sysfs attribute and rename in1_max_alarm to in1_alarm to reflect the situation.

* hwmon/f71882fg: Add support for f71889edHans de Goede2011-03-15
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | The code for determining a sensort type for temp1 was based on me misreading the datasheet, the tested registers do not determine what kind of sensor is actually reported as temp1.

* hwmon: (w83627ehf) Store rpm instead of raw fan speed dataGuenter Roeck2011-03-15
| | | | | | | | | | | | | Since the fan speed value can be above 0xff, we can no longer use that value to determine if the fan speed reading is valid. This makes it difficult to manipulate the stored fan speed register value. If we store rpm instead of the fan speed register value, we do not need to correct it if the fan divisor value is changed, and the above mentioned problem no longer exists.

* hwmon: (w83627ehf) Use 16 bit fan count registers if supportedGuenter Roeck2011-03-15
| | | | | | | | | | | | | | | Some of the chips supported by this driver have 13 bit or 16 bit fan count registers. This patch improves support for those registers, specifically for NCT6775F. With the changes in this patch, fan speed is reported correctly even if the fan divider is set to a low value, which results in a fan speed reading above 0xff. With this patch, the width of fan count registers is no longer used to determine if the chip has fan divider register(s) or not. A dedicated flag is used instead to determine if this is the case.

* hwmon: (pmbus) Continuously update temperature limit registersGuenter Roeck2011-03-15
| | | | | | | | | | | | PMBus only has one set of limit registers for up to three temperature sensors. Thus, changing a limit for one of the temperature sensors affects limits for other temperature sensors in the same page (and potentially multiple pages depending on the chip implementation). To handle this situation, re-read all temperature limit registers when updating sensor data. This way, all affected temperature limits are updated whenever the limit for a single sensor is changed.

* hwmon: (pmbus) Improve support for paged temperature sensorsGuenter Roeck2011-03-15
| | | | | | | | | | | | | Assumption so far was that PMBus devices would support TEMP2 and TEMP3 registers only on page 0, and that only the TEMP1 register would be used/supported on other pages. Turns out that is not correct. UCD92xx devices support TEMP1 and TEMP2 on page 0, and TEMP2 on other pages. So it is necessary to change the core code such that it does not make a page based assumptions about temperature register support. Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com>
