hwmon: (f71882fg) Add support for the F71869A

2011-07-03T11:32:53+00:00

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.

hwmon: (f71882fg) Add support for the F81865F

2011-03-26T09:45:02+00:00

Add support for the Fintek F81865F. It's essentially compatible with
the F71882FG, but has fewer inputs: 7 voltage, 2 temperature and 2 fan
inputs only.

hwmon: (f71882fg) Document all supported devices

2011-03-26T09:45:02+00:00

The list of supported devices was not always well documented in all
places. Clarify and list all devices in documentation, Kconfig and
the driver itself.

hwmon/f71882fg: Add support for f71869f and f71869e

2011-03-15T05:39:26+00:00

Note that these 2 are register compatible and report the same superio id,
but they are 2 distinct chips / models!

hwmon/f71882fg: Add support for f71889ed

2011-03-15T05:39:25+00:00

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.

hwmon: f71882fg: add support for the Fintek F71808E

2010-08-10T03:45:10+00:00

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.

hwmon: (f71882fg) Add support for the f71889fg (version 2)

2009-12-09T19:36:01+00:00

This adds support for the Fintek f71889fg to the f71882fg driver,
many thanks to Gerd v. Egidy for providing (remote) access to a
machine which such an ic.

Note that this bit of the patch:
-	val = SENSORS_LIMIT(val, 0, 255);
+
+	if (data->type == f71889fg)
+		val = SENSORS_LIMIT(val, -128, 127);
+	else
+		val = SENSORS_LIMIT(val, 0, 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.
