Pavel,
can you look into the omap4 thermal driver to see if it can be used ?
After some fixes... yes, it seems to be same hardware.
So this should be the way to go, but then we have others claim that
it should not be done because the OMAP3 sensors are too unreliable
to use for thermal decisions. Not really sure where that leaves us.
I am kind of opposed to have similar drivers for similar chips
in two different subsystems.
Is it possible to add the patch below to the omap thermal driver
and not use it for thermal decisions ?
Well... noone forces you to enable the driver, and I don't think it
will do any thermal decisions on N900 as it is ... so we should be ok.
Plus, it seems to work reasonably well (say +- 5 C), so situation does
not seem to be as bad as TI claims.
Nokia was actually using it in production.
Ok, I'll assume that omap3 support will be added to the omap thermal driver.
Thanks,
Guenter
