Hi All,
Below is the summary of ACPI and power management material I'm going to include
into my first pull request during the upcoming merge window. This is not the
whole material I'd like to be merged during that merge window, but that's
what I'm regarding as ready at the moment.
The ACPI enumeration changes for GPIO and SPI are still pending Grant's review,
but the rest appears to be in a reasonably good shape. The commits are
available from the tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git linux-next
Please let me know ASAP if you have any problems with any of them.
Thanks,
Rafael
