| | * hwmon: (sch56xx) Add support for the integrated watchdog (v2)Hans de Goede2012-03-202-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the watchdog integrated into the SMSC SCH5627 and SCH5636 superio-s. Since the watchdog is part of the hwmon logical device and thus shares ioports with it, the watchdog driver is integrated into the existing hwmon drivers for these. Note that this version of the watchdog support for sch56xx superio-s implements the watchdog chardev interface itself, rather then relying on the recently added watchdog core / watchdog_dev. This is done because currently some needed functionality is missing from watchdog_dev, as soon as this functionality is added (which is being discussed on the linux-watchdog mailinglist), I'll convert this driver over to using watchdog_dev.

| | | | | | | | ADM1276 is mostly compatible to ADM1275, with added support for input power measurement. Add support for it to the ADM1275 driver. Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com> Acked-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (pmbus/adm1275) Add support for second current limitGuenter Roeck2011-10-241-0/+8
| | | | | | | | | | | | ADM1275 supports a second current limit, which can be configured as either lower or upper limit. Add support for it and report it as either lower or upper critical current limit. Also replace error return code EINVAL for unsupported pages with ENXIO as this is more appropriate for the observed condition.

* hwmon: (coretemp) Don't use threshold registers for tempX_maxGuenter Roeck2011-09-211-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | With commit c814a4c7c4aad795835583344353963a0a673eb0, the meaning of tempX_max was changed. It no longer returns the value of bits 8:15 of MSR_IA32_TEMPERATURE_TARGET, but instead returns the value of CPU threshold register T1. tempX_max_hyst was added to reflect the value of temperature threshold register T0. As it turns out, T0 and T1 are used on some systems, presumably by the BIOS. Also, T0 and T1 don't have a well defined meaning. The thresholds may be used as upper or lower limits, and it is not guaranteed that T0 <= T1. Thus, the new attribute mapping does not reflect the actual usage of the threshold registers. Also, register contents are changed during runtime by an entity other than the hwmon driver, meaning the values cached by the driver do not reflect actual register contents. Revert most of c814a4c7c4aad795835583344353963a0a673eb0 to address the problem. Support for T0 and T1 will be added back in with a separate commit, using new attribute names.

* hwmon: (coretemp) Let the user force TjMaxJean Delvare2011-09-211-3/+4
| | | | | | | | | | | | | | | On old CPUs (and even some recent Atom CPUs) TjMax can't be read from the CPU registers, so it is guessed by the driver using a complex heuristic which isn't reliable. So let users who know their CPU's TjMax pass it as a module parameter.
