Please place it just like other bindings are placing it. Not in some
random order. See example-schema.

You should use common fan properties. If it was not merged yet, you must
rebase on patchset on LKML and mention the dependency in the change log
(---).

Use pwms, not own property for this.

Nope, reference watchdog.yaml and use its properties. See other watchdog
bindings for examples.

Node names should be generic. See also an explanation and list of
examples (not exhaustive) in DT specification:

NCT736X has 16 funtion pins, they can be
GPIO/PWM/FANIN/Reserved_or_ALERT#, and default is GPIO.
We would like to add such a property that can configure the function
pin for pin0~7 and pin10~17.

My original design is only for PWM/FANIN, however,
I noticed that we can change the design to "nuvoton,pin[0-7]$" and
"nuvoton,pin[10-17]$", like example in adt7475.yaml.
I'm not sure if this can be accepted or not, please kindly review this.

NCT7363 has a built-in watchdog timer which is used for conditionally
generating a system reset
output (INT#) if the microcontroller or microprocessor stops to
periodically send a pulse signal or
interface communication access signal like SCL signal from SMBus interface.

We only consider "Watchdog Timer Configuration Register" enable bit
and timeout setting.
Should we still need to add struct watchdog_device to struct nct736x_data?

ok, I'll change nct7363@22 to hwmon@22.

It looks you are writing custom pinctrl instead of using standard
bindings and frameworks.

It looks like the same problem as with other fan/Nuvoton bindings we
discussed some time ago on the lists.

Please do not duplicate threads, work and reviews:
https://lore.kernel.org/all/20230607101827.8544-5-zev@bewilderbeest.net/

I already gave same comments there.

I do not see correlation between watchdog.yaml and some struct. I did
not write anything about driver, so I don't understand your comments.

Anyway, I don't like that we are duplicating entire effort and our
review. Please join existing discussions, threads and build on top of it.

Thanks for your kindly sharing. I noticed that [1] defines some useful
properties, pwms and tach-ch, like you mentioned.

Therefore, I'll modify our design to follow the common fan properties in v2.

Thanks, I'll remove unused function in hwmon subsystem,
and consider a watchdog subsystem design if necessary.

+  FAN input monitors, and up to 16 independent PWM output with SMBus interface.
+  Besides, NCT7363Y has a built-in watchdog timer which is used for
+  conditionally generating a system reset output (INT#).
