2011-03-21hwmon: New driver for SMSC SCH5627Hans de Goede1-0/+22
SMSC SCH5627 Super I/O chips include complete hardware monitoring capabilities. They can monitor up to 5 voltages, 4 fans and 8 temperatures. The hardware monitoring part of the SMSC SCH5627 is accessed by talking through an embedded microcontroller. An application note describing the protocol for communicating with the microcontroller is available upon request. Please mail me if you want a copy.

2011-03-15hwmon/f71882fg: Add support for f71889edHans de Goede1-4/+8
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 Ladisch1-4/+8
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.

Add support for the IT8721F/IT8758E. These new chips differ from the older IT87xxF chips in the following ways: * ADC LSB is 12 mV instead of 16 mV. * PWM values are 8-bit instead of 7-bit. There are other minor changes we don't have to care about in the driver. Another change is that we will handle internal voltage scaling in the driver instead of delegating the work to user-space.
