Hi Linus,

Please pull from the tag

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
acpi-7.3-rc1-2

with top-most commit ea10c0b334e0dca944de2b5ecf57cf7e366674f4

Merge branches 'acpi-battery', 'acpi-button', 'acpi-soc' and 'acpi-pfrut'

on top of commit 0d508f1745b57272d4d4a3d50dc35aa2a3682238

Merge tag 'acpi-7.3-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

to receive more ACPI support updates for 7.3-rc1.

These update documentation to reflect recent changes in the upstream
ACPICA project, fix issues in the core ACPI device enumeration code
(one of which has been introduced recently), improve the primary
"physical" device lookup for ACPI device objects in that code, and
update ACPI device drivers:

- Update MAINTAINERS, CREDITS and ACPI subsystem documentation to
reflect recent changes in the upstream ACPICA project (Rafael
Wysocki)

- Prevent the core ACPI enumeration code from combining device
resources that overlap completely in order to avoid resource
conflicts during platform device registration because there are
drivers that expect such resources to be present (Rafael Wysocki)

- Defer device power initialization during ACPI-based device
enumeration to the point when the given device is known to be present
and functional and all of its dependencies have been met (Peixin Xie)

- Fix bus ID cleanup on device_add() failures during ACPI device object
registration (Hongyan Xu)

- Introduce a new helper function for looking up the primary "physical"
device for a given ACPI device object and update the core ACPI device
enumeration code to use that function (Rafael Wysocki)

- Protect all battery properties with a separated mutex in the ACPI
battery driver to prevent race conditions from occurring and avoid
evaluating the _BST ACPI control method multiple times in parallel
for the same battery device (Rong Zhang)

- Add DMI quirk for the Razer Blade Pro 17 early 2020 lid switch to the
ACPI button driver (Robin Everaars)

- Convert fixed clock rates in the ACPI driver for AMD SoCs (APD) to
use HZ_PER_MHZ and add a clock frequency for the HJMC01 I2C
controller to it (Hongnan Li and Xiangyang Yu)

- Fix a stack buffer overflow in query_capability() in the ACPI
platform firmware runtime update driver (Anirudh Prasad)

This material had a merge conflict against the driver core tree in
linux-next as per

Thanks!
