Merge tag 'powerpc-5.15-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull powerpc updates from Michael Ellerman:

- Convert pseries & powernv to use MSI IRQ domains.

- Rework the pseries CPU numbering so that CPUs that are removed, and
later re-added, are given a CPU number on the same node as
previously, when possible.

- Add support for a new more flexible device-tree format for specifying
NUMA distances.

- Convert powerpc to GENERIC_PTDUMP.

- Retire sbc8548 and sbc8641d board support.

- Various other small features and fixes.

cpufreq: powernv: Fix init_chip_info initialization in numa=off

In the numa=off kernel command-line configuration init_chip_info() loops
around the number of chips and attempts to copy the cpumask of that node
which is NULL for all iterations after the first chip.

Hence, store the cpu mask for each chip instead of derving cpumask from
node while populating the "chips" struct array and copy that to the
chips[i].mask

Pull more power management updates from Rafael Wysocki:
"These include cpufreq core simplifications and fixes, cpufreq driver
updates, cpuidle driver update, a generic power domains (genpd)
locking fix and a debug-related simplification of the PM core.

Specifics:

- Drop the ->stop_cpu() (not really useful) and ->resolve_freq()
(unused) cpufreq driver callbacks and modify the users of the
former accordingly (Viresh Kumar, Rafael Wysocki).

- Add frequency invariance support to the ACPI CPPC cpufreq driver
again along with the related fixes and cleanups (Viresh Kumar).

- Update the Meditak, qcom and SCMI ARM cpufreq drivers (Fabien
Parent, Seiya Wang, Sibi Sankar, Christophe JAILLET).

- Rename black/white-lists in the DT cpufreq driver (Viresh Kumar).

- Add generic performance domains support to the dvfs DT bindings
(Sudeep Holla).

- Refine locking in the generic power domains (genpd) support code to
avoid lock dependency issues (Stephen Boyd).

- Update the MSM and qcom ARM cpuidle drivers (Bartosz Dudziak).

- Simplify the PM core debug code by using ktime_us_delta() to
compute time interval lengths (Mark-PK Tsai)"

cpufreq: powernv: Migrate to ->exit() callback instead of ->stop_cpu()

Commit 367dc4aa932b ("cpufreq: Add stop CPU callback to cpufreq_driver
interface") added the ->stop_cpu() callback to allow the drivers to do
clean up before the CPU is completely down and its state can't be
modified.

At that time the CPU hotplug framework used to call the cpufreq core's
registered notifier for different events like CPU_DOWN_PREPARE and
CPU_POST_DEAD. The ->stop_cpu() callback was called during the
CPU_DOWN_PREPARE event.

This is no longer the case, cpuhp_cpufreq_offline() is called only
once by the CPU hotplug core now and we don't really need two
separate callbacks for cpufreq drivers, i.e. ->stop_cpu() and
->exit(), as everything can be done from the ->exit() callback
itself.

Migrate to using the ->exit() callback instead of ->stop_cpu().
