Drivers should check this flag I would call this IORESOURCE_IRQ_WAKE which is (a) simpler and easier to read and (b) it sort of matches the "wakeirq" naming convention. This is not a big deal if you insist on this name and for a good reason, but just something I would do differently.

I think that patches [5-8/13] from this series are significant framework changes, so it would make sense to route them via the ACPI tree. If this is fine with everybody, I will queue them up for merging into 6.1 (probably in the second half of the upcoming merge window).

I believe it's fine from GPIO ACPI perspective (there shouldn't be conflict, but if you wish you always may take this PR [1] to your tree (it's already in GPIO tree pending v6.1), it may be considered as immutable tag.

This material is in the mainline now, but the branch is still there in case you need it: git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ acpi-wakeup It won't be necessary any more after 6.1-rc1 is out, though, I suppose.

Dmitry, What are the next steps to getting the I2C patches landed? Should I push out a new series that's rebased on 6.1-rc1?
