Hi Jean, Guenter,
  I'm part way through converting w83627ehf to use the devm_hwmon_device_register_with_info
interface and had some questions I'd appreciate the answer to.  My WIP
code is attached below.

  a) In the existing driver, all the pseudo files are showing up as:
     /sys/devices/platform/w83627ehf.656/blah_input
     with the rework:
     /sys/devices/platform/w83627ehf.656/hwmon/hwmon1/

     my reading is that the reworked one is correct?
     Although I guess the change is a pain for people with paths
     in tools.

  b) The device has an intrusion0_alarm & intrusion1_alarm
     that seems pretty common looking in drivers/hwmon - some other
     devices have a intrustion%d_beep.  Does it make sense to add
     a new hwmon_intrusion type to hwmon_sensor_types  ?

  c) The device has a bunch more pwm variants:
     pwm2_max_output, pwm2_start_output, pwm2_step_output, pwm2_stop_output,
     pwm2_stop_time, pwm2_target, pwm2_tolerance

     for each/some of it's outputs.   What's the right thing to
     do there? Add them all to hwmon_pwm_attr_templates ?
     (Unfortunately it looks like everyone has fun with their own
      pwm settings).

For reference, I seem to have a w83667hg on an ASRock P55M Pro.

The current status is that 'reading' seems to work (from what I can tell
but not looked at the PWM), and I've not converted the writers yet.

Thanks in advance,

Dave

No one should have absolute path names like the above in their tools.
So far none of the driver conversions caused trouble, so hopefully
we should be fine.

Yes, we should add hwmon_intrusion to hwmon_sensor_types, with _alarm
and _beep as supported attributes.

We'll have to keep sysfs files for those for the time being,
unless there are some which are officially listed in
Documentation/hwmon/sysfs-interface.rst.

Good start. I would suggest to run your patch through checkpatch.
It will tell you, for example, that S_IRUGO et al ran out of favor,
and that you are supposed to use octals instead.

Thanks,

OK, great.

OK, will do.

OK, that's a bit messy; so just keep the existing sysfs code - do
I need to tweak that to match the new directory path?
Would another way be to use @extra_groups on the with_info call?

Yeh I've already done that and used it to get rid of most of my space/tab
screwups;  I'll fix the remains up before I post the final version.

I should nail the rest of this either this weekend or next.

Thanks again for your comments,

Dave

Yes, that is what you are supposed to do.
