5da556e33f hwmon: (f71882fg) Add support for the F71869A
The F71869A is almost the same as the F71869F/E, except that it has
the normal number of temp and pwm zones for a F71882FG derived chip,
rather then the limited number of the F71869F/E.

Commit a321cedb12 excludes CPU models 0xe, 0xf,
0x16, and 0x1a from TjMax temperature adjustment, even though several of those
CPUs are known to have TiMax other than 100 degrees C, and even though the code
in adjust_tjmax() explicitly handles those CPUs and points to a Web document
listing several of the affected CPU IDs.

Reinstate original TjMax adjustment if TjMax can not be determined using the
IA32_TEMPERATURE_TARGET register.

ec693fe528 hwmon: (abituguru) Depend on DMI
The abituguru drivers are only built on X86, where DMI support is now
enabled by default. So let these drivers depend on DMI, for the
following gains:
* Robustness and safety. Detection of these devices is weak and uses
  non-standard methods, it should really be limited to Abit boards
  unless the user explicitly asks otherwise.
* Code simplicity. The code is easier to read without ifdefs.
* Better build testing coverage. Now there's only one way to build the
  drivers, so no risk of build failure on exotic systems.

f4e0bcf06b hwmon: (coretemp) Add comments describing the handling of HT CPUs

Commit e40cc4bdfd ("x86/hwmon: register alternate sibling upon CPU
removal") extends this functionality to register the HT sibling of a CPU
which is taken offline, to ensure that sensor attributes are provided if
at least one HT sibling of a core is online.

Add comments into the code describing the functionality in some more
detail.

bb74e8ca35 hwmon: (coretemp) Fix compile error if CONFIG_SMP is not defined
cpu_sibling_mask() is not defined unless CONFIG_SMP is defined, so it
must not be used directly in the code without ifdef protection.

To solve the problem and avoid ifdefs in the code, define
for_each_sibling() and use it instead.

Make the LM75/LM75A device detection faster:

* Don't read the current temperature value when we don't use it.
* Check for unused bits in the configuration register as soon as we
  have read its value.
* Don't use word reads, not all devices support this, and some which
  don't misbehave when you try.
* Check for cycling register values every 40 register addresses
  instead of every 8, it's 5 times faster and just as efficient.

Some of these improvements come straight from the user-space
sensors-detect script, so both detection routines are in line now.

d668a8b022 hwmon: (lineage-pem): Fix in1 voltage alarm sysfs attributes
The alarm bit assumed to be a low voltage alarm bit is not set for low voltage
alarms, and the alarm bit assumed to be a high voltage alarm turns out to be a
general alarm bit which is set for both low and high voltage alarms.

Remove the in1_min_alarm sysfs attribute and rename in1_max_alarm to in1_alarm
to reflect the situation.

3cad402281 hwmon/f71882fg: Add support for f71889ed
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.

e48a7f1a71 hwmon/f71882fg: Break out test for auto pwm's controlled by digital readings
Putting this check in its own switch case rather then in the switch case
for adding pwm auto point sysfs attr is cleaner. This is a preparation patch
for adding support for more different models.
