[lm-sensors] Needed support for SMSC LPC47M292

[lm-sensors] Needed support for SMSC LPC47M292

[Antonio RAGO]

Hi all
I'm writing you about an LPC47M292 chip.
I have and ibm thinkcenter with kernel 2.6.22-3-686 (debian)
and I'm trying to recognize the sensors.
sensors-detect claim that there is the chip 
    `SMSC LPC47M292 Super IO Fan Sensors'
and I've loaded the corresponding module
but even if the module is loaded and according to the messages log it's 
the right one
when I try to run sensors, the program claims that no chipset has been 
found.
(In the following i'm reporting also i2c stuff even if it seems to me 
that they are useless)

raven:~# sensors
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

utilities to read temperature/voltage/fan sensors

Maybe I'm missing something, but it seems to me that it's not working.
I can easily do any test on this computer if it's needed.
Thank you in advance
Antonio

This is indeed strange. Please provide the output of:
strace sensors
ls -l /sys/class/hwmon
ls -R /sys/class/hwmon/*

Hi Jean,

OK, this is your hardware monitoring chip. The "problem" is that the
driver only created fan speed _control_ files (pwm*) and no speed
_monitoring_ files (fan*). This is why libsensors doesn't recognize it.

The SMSC LPC47M292 features can be individually disabled (the pins can
be used for alternate functions). It seems that this is the case for
you. If you can rebuild the smsc47m1 driver with
CONFIG_HWMON_DEBUG_CHIP=y it should tell you about disabled features.

It is possible that there is a bug in the driver. After all I only
added LPC47M292 support recently, it did not get much testing yet. If
you send me a dump of your chip (use isadump -f 2048 128) I can
double-check. But it could also be that your system is not wired for
fan speed monitoring. Do you have any reason to believe that it is? Is
it documented by the manufacturer? Does your BIOS display fan speed
values?

As long as you don't get fan speed monitoring to work, I suggest that
you don't play with the fan speed control features (if they are wired
at all...) Changing the fan speeds with no way to validate these
changes sounds a bit dangerous.
