Subject: [GIT PULL] More ACPI updates for v4.20-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-4.20-rc1-2

with top-most commit 6a9b593d4b6f5994209456de7a3c2db0974b5dda

 ACPI / PMIC: xpower: Add depends on IOSF_MBI to Kconfig entry

on top of commit bd6bf7c10484f026505814b690104cdef27ed460

 Merge tag 'pci-v4.20-changes' of
git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

to receive additional ACPI updates for 4.20-rc1.

These rework the handling of the P-unit semaphore on Intel
Baytrail and Cherrytrail systems to avoid race conditions and
excessive overhead related to it (Hans de Goede).

There was a merge conflict between this material and the i2c
tree (merged now) in linux-next that should be straightforward
to resolve [1].

Thanks!
