2011-03-26hwmon: (pmbus) Fix temperature limit register accessGuenter Roeck1-34/+36
Commit 8677011 added auto-update to temperature limit registers. Unfortunately, the update flag is also used to determine if an attribute is writable, which results in read-only temperature limit registers.

2011-03-21hwmon: (lm75) Speed up detectionJean Delvare1-21/+19
Make the LM75/LM75A device detection faster: * Don't read the current temperature value when we don't use it. * Check for unused bits in the configuration register as soon as we have read its value. * Don't use word reads, not all devices support this, and some which don't misbehave when you try. * Check for cycling register values every 40 register addresses instead of every 8, it's 5 times faster and just as efficient. Some of these improvements come straight from the user-space sensors-detect script, so both detection routines are in line now.

2011-03-14hwmon/f71882fg: Add support for f71889edHans de Goede1-11/+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.
