Re: [PATCH 3/4] hwmon: (adt7475) Add thermal zone sensor support

[sashiko-bot@kernel.org]

> Register the temperature channels as thermal zone sensors. Sensor id N
> is temperature channel N, i.e. temp(N+1). Document this in adt7475.rst.
> 
> The hwmon core reads a sensor's temperature while registering the
> thermal zone, from within hwmon_device_register_with_info(). Read the
> chip limits before registering, so that the temperature encoding
> (CONFIG5 two's complement bit) is known for that first read.
> 
> With CONFIG_THERMAL_OF, devices that have a devicetree node, or sit
> below one (the hwmon core uses the nearest ancestor's node), see two
> changes:
> - Each temperature channel that no thermal zone uses logs
>   "tempN_input not attached to any thermal zone" once at probe.
> - When a thermal zone uses a channel, the hwmon core sets that
>   channel's min and max limit registers to the zone's current trip
>   window, as it does for other drivers registering thermal sensors.
