I noticed the lack of pm_* from the core.

This will be noticed very quickly since the means the problem seen
in e.g. commit 04f59143b571 and the wakeup IRQ business will make it
impossible to do power-efficient drivers until that is resolved.

It'd be nice to have it to PM right from the start, and the I2C core has
all the right infrastructure in place, so when this stabilize I'd say
atleast it'd be *nice* if the PM business was added in the same
kernel release that introduce this core infrastructure, even if it will
be a separate patch.

I.e. I consider that more of necessary bread and butter and less of
nice to have topping on the cake.

What I have seen that leaf vendors doing (i3c) device drivers do
otherwise is complain "it is broken" and then they start to hack
around it instead of helping out with the core. (I think you're
well aware of that phenomenon.)

Yours,
Linus Walleij
