2011-02-23hwmon: adt7461: support Thermal ThrottlingPrashant Gaikwad
The driver now supports thermal throttling. When the temperature reaches a certain threshold, thermal throttling is enabled and when the chip cools off to a certain threshold, throttling is disabled.

2010-09-28hwmon (coretemp): Fix build breakage if SMP is undefinedGuenter Roeck
Commit e40cc4bdfd4b89813f072f72bd9c7055814d3f0f introduced a build breakage if CONFIG_SMP is undefined. This commit fixes the problem. This fix is only a workaround. For a real fix, cpu_sibling_mask() should be defined in UP include code, eg in linux/smp.h, and asm/smp.h should not be included directly. This fix is currently not possible because asm/smp.h defines cpu_sibling_mask() unconditionally and is included directly from many source files.

2010-09-24x86/hwmon: register alternate sibling upon CPU removalJan Beulich
Just like pkgtemp registers another core of the same package when one gets removed, coretemp should register another hyperthread (if available) in that situation. As pointed out in the patch fixing the respective code in pkgtemp, the list protectng mutex must be dropped before calling coretemp_device_add(), and due to the restructured loop (including an explicit return) the "safe" variant of the list iterator isn't needed anymore.

2010-09-24x86/hwmon: avoid deadlock on CPU removal in pkgtempJan Beulich
pkgtemp_device_remove(), holding the list protecting mutex, calls pkgtemp_device_add(), which itself wants to acquire the same mutex. Holding the mutex over the entire loop body in pkgtemp_device_remove() isn't really necessary, as long as the loop gets exited after processing the matched CPU. Once exiting the loop after removing an eventual match, there's no need for using the "safe" list iterator anymore.

In commit 0dca94baeab4a1a514841b0a4c8e3a51dfb4d5ae the call to platform_driver_unregister() was made conditional upon !HOTPLUG_CPU, but the return value from coretemp_init() was left to indicate an error. This isn't correct, as the negative return value indicates to the module loader that initialization failed, which isn't intended here and results in dangling pointers.

2010-08-25hwmon: (k8temp) Differentiate between AM2 and ASB1Andreas Herrmann
Commit 8bf0223ed515be24de0c671eedaff49e78bebc9c (hwmon, k8temp: Fix temperature reporting for ASB1 processor revisions) fixed temperature reporting for ASB1 CPUs. But those CPU models (model 0x6b, 0x6f, 0x7f) were packaged both as AM2 (desktop) and ASB1 (mobile). Thus the commit leads to wrong temperature reporting for AM2 CPU parts. The solution is to determine the package type for models 0x6b, 0x6f, 0x7f. This is done using BrandId from CPUID Fn8000_0001_EBX[15:0].

Add support for exposing all GPIO pins as analog voltages. Though this is not an ideal use of the chip, some hardware engineers may decide that the LTC4245 meets their design requirements when studying the datasheet. The GPIO pins are sampled in round-robin fashion, meaning that a slow reader will see stale data. A userspace application can detect this, because it will get -EAGAIN when reading from a sysfs file which contains stale data. Users can choose to use this feature on a per-chip basis by using either platform data or the OF device tree (where applicable). Signed-off-by: Ira W.
