As far as I can see from the code in this driver, it looks like this
driver should also be compatible with the nct7362; shall we add the ID
table entry for it now? (Though I only have a datasheet for the
nct7362, not the nct7363, so I don't know exactly how they differ.)
As far as I know, the difference between these two ICs is 0x2A~0x2C
Fading LED for 7362, and 0x2A Watchdog Timer for 7363.
In my v1 patch, I indeed add the nct7362 to the ID table, however,
this makes it more complicated and our datasheet isn't public yet.
I think maybe supporting more chips will be done in the future, but not now.
If the only differences are in features the driver doesn't utilize, I'm
not clear on how it adds any complexity. As far as I'm aware, neither
datasheet is public (NCT7363 nor NCT7362), so if we're going to have a
public driver for one, why not also do so for the other? It's a single
additional line -- and furthermore, having made that change and tested
it out, I can report that the driver seems to work just fine on NCT7362
hardware as well.
