2011-04-29hwmon: (adm1021) Clarify documentation regarding Xeon processorsJean Delvare
Recent Xeon processor thermal sensors are supported by the coretemp driver and not the adm1021 driver. Only one old generation of Xeon processors (the first Netburst ones) are supported by the adm1021 driver.

2011-03-14hwmon/f71882fg: Add support for f71889edHans de Goede
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.

2011-02-16hwmon: (jc42) do not allow writing to locked registersClemens Ladisch
On systems where the temperature sensor is actually used, the BIOS is likely to have locked the alarm registers. In that case, all writes through the corresponding sysfs files would be silently ignored. To prevent this, detect the locks and make the affected sysfs files read-only.
