[PATCH net-next 3/3] net: phy: marvell-88q2xxx: enable temperature sensor in mv88q2xxx_config_init

[Dimitri Fedrau]

Temperature sensor gets enabled for 88Q222X devices in
mv88q222x_config_init. Move enabling to mv88q2xxx_config_init because
all 88Q2XXX devices support the temperature sensor.

Hi Dimitir,

Thanks for your work.

Is this true for mv88q2110 devices too? The current implementation only 
enables it for mv88q222x devices. The private structure is not even 
initialized for mv88q2110, and currently crashes. I have fixed that [1], 
but I'm not sure if that should be extended to also enable temperature 
sensor for mv88q2110?

In either case with [1] for an unrelated fix this is tested on 
mv88q2110.

The change itself looks fine:

Reviewed-by: Andrew Lunn <andrew@lunn.ch>

but is the sensor actually usable if the PHY has not yet been
configured?

Architecturally, it seems odd to register the HWMON in probe, and then
enable it in config_init.

Yes, according to the datasheet. I don't have a mv88q2110 device, so I
can't test it. I would like to see it enabled. So if you can test it and
it works why not enabling it. Thanks for finding this.

I think it makes sense to enable it in probe as well. I just moved it to
config_init because of the PHYs hard reset. Before
https://lore.kernel.org/netdev/20250118-marvell-88q2xxx-fix-hwmon-v2-1-402e62ba2dcb@gmail.com/
it was already done in mv88q2xxx_hwmon_probe. I will come up with a patch.

Why the hell are register addresses in this driver in decimal?

Maybe because 802.3 uses decimal? Take a look at Table 45–3—PMA/PMD
registers for example.

Shocker - some documentation gives driver addresses for PHYs in
decimal.

It then becomes a pain to have to manually translate back and
forth between hex and decimal if one is reading the driver code and
referring back to the documentation.

Agreed. Is it worth to change addresses to hexadecimal numbers and use
BIT and GENMASK for the bits ?

Thanks for confirming. I will attempt to test and enable this once as 
soon as I can.
