Guenter Roeck 0038389add hwmon: (f71882fg) Fix build warning
Fix:

warning: 'address' may be used uninitialized in this function [-Wuninitialized]

While this is a false warning, the patch reduces module size on x86_64 by
approximately 175 bytes, so it is still worth the effort.

Hans de Goede 6543439f19 hwmon/f71882fg: Make the decision wether to register fan attr. per fan
Before this patch the f71882fg driver completely fails to initialize
on systems which have reserved settings in the pwm enable register, and
it disables all auto pwm sysfs attributes if any fan is controlled by
a digital sensor reading.

This patch changes the fail to initialize into don't register any attributes
for the fan for which there are reserved settings in the pwm enable register
and also makes the not registering of auto pwm sysfs attributes a per fan
thing.

Hans de Goede 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.

Allow device probing to recognise the Fintek F71808E.

Sysfs interface:
 * Fan/pwm control is the same as for F71889FG
 * Temperature and voltage sensor handling is largely the same as for
   the F71889FG
  - Has one temperature sensor less (doesn't have temp3)
  - Misses one voltage sensor (doesn't have V6, thus in6_input refers to
    what in7_input refers for F71889FG)

For the purpose of the sysfs interface fxxxx_in_temp_attr[] is split up
such that it can largely be reused.

+		val = SENSORS_LIMIT(val, -128, 127);

Changes behaviour for already supported models, the new behaviour is correct
as the already supported models have bit 7 of the involved registers fixed at
0, so the previous behaviour which allowed setting temp zone limits > 127
was not correct.

Hans de Goede fc16c56e69 hwmon: (f71882fg) Fix sysfs file removal
There is a bug in the old sysfs file removal, as it uses fxxxx_in_temp_attr
to remove the in and temp sysfs attributes, but fxxxx_in_temp_attr has
temp#_alarm, where as f71858fg_in_temp_attr has temp#_max_alarm, so
the temp#_max_alarm attributes for the f71858fg never get removed.

the creation instead of being (too) clever, this will also avoid similar
bugs in the future.

* Rename a number of sysfs attr arrays to make their function clearer
* Move the pwm#_auto_channels_temp attribute from the common to all
  models fan attr array to the per model auto mode pwm attr arrays, so
  that all the auto mode pwm attr are grouped together, and thus can be
  left out on models where we don't support auto pwm mode
* Put fan_beep attr in their own array, so that only auto mode pwm attr
  remain in the per model pwm sysfs attr arrays.
* Put the 4th special fan input for the f8000 in its own array, so that only
  auto mode pwm attr remain in the per model pwm sysfs attr arrays.

Jean Delvare cd659fd0d7 hwmon: Fix more __devexit_p glitches
Make sure __devexit and devexit_p() match in all hwmon drivers.
Suggested by a similar fix from Mike Frysinger.

Hans de Goede 18632f84fa hwmon: Fix ACPI resource check error handling
This patch fixes a number of cases where things were not properly
cleaned up when acpi_check_resource_conflict() returned an error,
causing oopses such as the one reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=483208

Jean Delvare 603eaa1bdd hwmon: (f71882fg) Hide misleading error message
If the F71882FG chip is at address 0x4e, then the probe at 0x2e will
fail with the following message in the logs:
f71882fg: Not a Fintek device

This is misleading because there is a Fintek device, just at a
different address. So I propose to degrade this message to a debug
message.

Jean Delvare b9acb64a38 hwmon: Check for ACPI resource conflicts
Check for ACPI resource conflicts in hwmon drivers. I've included
all Super-I/O and PCI drivers.

I've voluntarily left out:
* Vendor-specific drivers: if they conflicted on any system, this would
  pretty much mean that they conflict on all systems, and we would know
  by now.
* Legacy ISA drivers (lm78 and w83781d): they only support chips found
  on old designs were ACPI either wasn't supported or didn't deal with
  thermal management.
* Drivers accessing the I/O resources indirectly (e.g. through SMBus):
  the checks are already done where they belong, i.e. in the bus drivers.

Hans de Goede 2f650631b3 hwmon: (f71882fg) Fix fan_to/from_reg prototypes
The RPM after conversion from / before conversion to a register value can be
much more than 65535 (up to 1500000), so putting this into an u16 can cause
overflows. This changes the functions to use an int to store / get RPM instead.
