    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
