Remove platform data & add devicetree support.


Unless I am missing something, this doesn't just add devicetree support,
it actually _mandates_ devicetree support. There are no defaults.
That is not acceptable.
I agree with you. It is best to have some defaults & then overwrite
based on DT properties.
But in that case we would have to assume that all fans are enabled
irrespective of their hardware connections in the schematics(example
fan_enable).

I'm not sure if that is fine. But if you feel that is alright then
I'll rewrite the driver to assume
everything is enabled with default values.

That would still be a functional change, or am I missing something ?
It would overwrite any configuration written by a BIOS/ROMMON.
With that, driver would take the current chip configuration as default &
just configure specific config specified in DT(if any) & continue with
initialization?

Yes.

Thanks,
Guenter
