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.Signed-off-by: Guenter Roeck

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.Signed-off-by: Hans de Goede

The code for determining a sensort type for temp1 was based on me misreading
the datasheet, the tested registers do not determine what kind of sensor
is actually reported as temp1. Instead the enable / disable certain additional
digital sensor readouts throug PECI / AMDSI, etc. Independent of these settings
temp1 is still reading an external BJT or thermistor as configured by the
Temperature Sensor Type Register (0x6b).Signed-off-by: Hans de Goede

NCT6776F and NCT6775F support debouncing the fan RPM signal. This can
help improve the stability of th RPM signal for some fans (Arctic cooling
fans for example).
This patch adds a module parameter fan_debounce, which when set to 1 enables
debounce for all fans that the chip supports.Signed-off-by: Ian Dobson

Since the fan speed value can be above 0xff, we can no longer use
that value to determine if the fan speed reading is valid. This
makes it difficult to manipulate the stored fan speed register value.If we store rpm instead of the fan speed register value, we do not
need to correct it if the fan divisor value is changed, and the above
mentioned problem no longer exists.Signed-off-by: Guenter Roeck

Some of the chips supported by this driver have 13 bit or 16 bit fan count
registers. This patch improves support for those registers, specifically for
NCT6775F. With the changes in this patch, fan speed is reported correctly even
if the fan divider is set to a low value, which results in a fan speed reading
above 0xff.With this patch, the width of fan count registers is no longer used to determine
if the chip has fan divider register(s) or not. A dedicated flag is used instead
to determine if this is the case.Signed-off-by: Guenter Roeck

For newer chips, several registers are banked and thus need to be 16 bit.
Also, register addresses change.To prepare for those chips, convert affected register arrays to 16 bit,

PMBus only has one set of limit registers for up to three temperature sensors.
Thus, changing a limit for one of the temperature sensors affects limits for
other temperature sensors in the same page (and potentially multiple pages
depending on the chip implementation). To handle this situation, re-read all
temperature limit registers when updating sensor data. This way, all affected
temperature limits are updated whenever the limit for a single sensor is
changed.Signed-off-by: Guenter Roeck

Assumption so far was that PMBus devices would support TEMP2 and TEMP3 registers
only on page 0, and that only the TEMP1 register would be used/supported
on other pages.Turns out that is not correct. UCD92xx devices support TEMP1 and TEMP2 on
page 0, and TEMP2 on other pages. So it is necessary to change the core code
such that it does not make a page based assumptions about temperature register
support.Signed-off-by: Guenter Roeck

So far, it seemed like fans would either all be in page 0, or that
there would be one page per fan.Turns out this was a wrong assumption. There is at least one PMBus
fan controller which supports three pages with four fans each.

Some PMBus chips do not support the VOUT_MODE register. To make matters worse,
such chips may not return an error when reading the register either, but instead
return 0xff.Check if the register exists using pmbus_check_byte_register() before reading
its value. In addition, validate the returned value and ignore it if it is 0xff
(which is invalid).Reported-by: Greg Schnorr

So far, the driver updates temp_auto_hyst and temp_auto_off if temp_auto_min changes.
This may cause problems if temp_auto_off was not configured before configuring
temp_auto_min, because one of the variables used (off_desired) is not initialized
in this case.To simplify the code, and for consistency with other drivers, no longer update the delta
between "min" and "off" until the user sets the "off" value again.Signed-off-by: Guenter Roeck
