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 From 1cc4523c938824caa589769497abf71449511326 Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Sun, 17 Nov 2019 00:34:36 +0000 Subject: [PATCH] hwmon: (w83627ehf) convert to with_info interface Convert the old hwmon_device_register code to devm_hwmon_device_register_with_info.
