This is repost based on bmaly's original hwmon patchset. I've fixed various
issues brought up by reviewers.
bmaly originally wrote:
"BZ 467994, 250561, 446061
This is an update for drivers/hwmon. Our tree is badly out of date. This
update provides support for many new chips (so as to support the latest
production hardware) as well as many bugfixes. Some dependent functions
were also backported as well. lmsensors does not work on quite a bit of
new hardware without this update.
Ive tested various drivers with success on as many types of hardware I
could find. No problems found."
I have successfully tested across various HW in Beaker and in RHTS, using
sensors-detect, sensors, and the lm_sensors initscript.
Resolves BZ 476994, 250561, and 446061.
- dmi_walk fixes
- f75375_probe kfree fixed
- adt7473.c warning WAR
- kabi fixes, still building i2c-isa kernel module for external use
Resolves BZ 467994 250561 446061

* The F71805F/FG is a LPC Super-I/O chip made by Fintek. It integrates
* complete hardware monitoring features: voltage, fan and temperature
* sensors, and manual and automatic fan speed control.
*
+ * The F71872F/FG is almost the same, with two more voltages monitored,
+ * and 6 VID inputs.
+ *
+ * The F71806F/FG is essentially the same as the F71872F/FG. It even has

+ TEMP_FAN_MAP
+ Temp channel control which pwm fan, bitfield, bit 0 indicate pwm1...
+ It's possible two or more temp channels control the same fan, w83793

+ the related Fan.
+ It's possible one fan is not in any mapping of 6 temp channels, this
+ means the fan is manual mode
+
+ TEMP_PWM_ENABLE
+ Each temp channel has its own SmartFan mode, and temp channel
+ control fans that are set by TEMP_FAN_MAP
+ 0: SmartFanII mode
+ 1: Thermal Cruise Mode
+
+ TEMP_CRUISE
+ Target temperature in thermal cruise mode, w83793 will try to turn

+ temperature.
+
+ TEMP_TOLERANCE
+ If Temp higher or lower than target with this tolerance, w83793
+ will take actions to speed up or slow down the fan to keep the
+ temperature within the tolerance range.
