Ezequiel,
As the author of the armada_thermal driver, it would be great if you
can be the goalkeeper for all armada_thermal changes, and I'd prefer to
get your ACK/NAK before applying/dropping any armada thermal patches.
Can you please take a look at this patch?

BTW, Grzegorz, for the PM callbacks, you'd better to either use
__maybe_unused so that gcc can drop it if it's not used, or use #ifdef
to compile them out when CONFIG_PM_SLEEP is not set.
You can also refer to this patch https://patchwork.kernel.org/patch/931
1025/
