2016-12-09hwmon: (core) Clarify use of chip attributesGuenter Roeck
Describing chip attributes as "attributes which apply to the entire chip" is confusing. Rephrase to "attributes which are not bound to a specific input or output". Also rename hwmon_chip_attr_templates[] to hwmon_chip_attrs[] to indicate that the respective strings strings are not templates but actual attribute names.

2016-12-09hwmon: (core) Add support for string attributes to new APIGuenter Roeck
The new API is so far only suited for data attributes and does not work well for string attributes, specifically for the 'label' attributes. Provide a separate callback function for those. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2016-12-09hwmon: (coretemp) Simplify package managementThomas Gleixner
Keeping track of the per package platform devices requires an extra object, which is held in a linked list. The maximum number of packages is known at init() time. So the extra object and linked list management can be replaced by an array of platform device pointers in which the per package devices pointers can be stored. Lookup becomes a simple array lookup instead of a list walk. The mutex protecting the list can be removed as well because the array is only accessed from cpu hotplug callbacks which are already serialized.

2016-12-09hwmon: (coretemp) Use proper error codes in cpu online callbackThomas Gleixner
The cpu online callback returns success unconditionally even when the device has no support, micro code mismatches or device allocation fails. Only if CPU_HOTPLUG is disabled, the init function checks whether the device list is empty and removes the driver. This does not make sense. If CPU HOTPLUG is enabled then there is no point to keep the driver around when it failed to initialize on the already online cpus. The chance that not yet online CPUs will provide a functional interface later is very close to zero. Add proper error return codes, so the setup of the cpu hotplug states fails when the device cannot be initialized and remove all the magic cruft.

2016-12-09hwmon: (coretemp) Simplify sibling managementThomas Gleixner
The coretemp driver provides a sysfs interface per physical core. If hyperthreading is enabled and one of the siblings goes offline the sysfs interface is removed and then immeditately created again for the sibling. The only difference of them is the target cpu for the rdmsr_on_cpu() in the sysfs show functions. It's way simpler to keep a cpumask of cpus which are active in a package and only remove the interface when the last sibling goes offline. Otherwise just move the target cpu for the sysfs show functions to the still online sibling. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2016-12-09hwmon: (coretemp) Fixup target cpu for package when cpu is offlinedThomas Gleixner
When a CPU is offlined nothing checks whether it is the target CPU for the package temperature sysfs interface. As a consequence all future readouts of the package temperature return crap: 90000 which is Tjmax of that package. Check whether the outgoing CPU is the target for the package and assign it to some other still online CPU in the package. Protect the change against the rdmsr_on_cpu() in show_crit_alarm().

2016-09-18hwmon: (nct6775) Add support for multiple virtual temperature sourcesGuenter Roeck
For virtual temperatures, the actual temperature values are written by software, presumably by the BIOS. This functionality is (as of right now) supported on NCT6791D, NCT6792D, and NCT6793D. On those chips, the temperatures are written into registers 0xea..0xef on page 0. This is known to be used on some Asus motherboards, where the actual temperature source can be configured in the BIOS. Report the 'virtual' temperatures for all monotoring sources to address this situation. Example for the resulting output (as seen with the 'sensors' command): nct6791-isa-0290 Adapter: ISA adapter ... Virtual_TEMP: +31.0°C PECI Agent 0: +38.5°C Virtual_TEMP: +32.0°C ...

2016-09-09hwmon: (xgene) access mailbox as RAMArnd Bergmann
The newly added hwmon driver fails to build in an allmodconfig kernel: ERROR: "memblock_is_memory" [drivers/hwmon/xgene-hwmon.ko] undefined! According to comments in the code, the mailbox is a shared memory region, not a set of MMIO registers, so we should use memremap() for mapping it instead of ioremap or acpi_os_ioremap, and pointer dereferences instead of readl/writel. The driver already uses plain kernel pointers, so it's a bit unusual to work with functions that operate on __iomem pointers, and this fixes that part too. I'm using READ_ONCE/WRITE_ONCE here to keep the existing behavior regarding the ordering of the accesses from the CPU, but note that there are no barriers (also unchanged from before). I'm also keeping the endianness behavior, though I'm unsure whether the message data was supposed to be in LE32 format in the first place, it's possible this was meant to be interpreted as a byte stream instead.
