[GIT PULL] power sequencing updates for v7.4-rc1

[Bartosz Golaszewski]

Linus,

Please pull the following set of power sequencing updates for this merge
window. The bulk of added lines are kunit tests that comprehensively verify
the core functionality of the power sequencing framework. Other than that, we
have another pwrseq driver: Renesas RZ/G3L Power Ready and support for more
models in pwrseq-pcie-m2. We also added a new consumer-facing API in the form
of pwrseq_is_controllable() function which allows consumers to check if
a given target resource is actually host-controllable.

The merge commits you see are:
- immutable branch provided to cross-tree users of the new API:
  pwrseq_is_controllable()
- pulling in of mainline tags whenever upstream fixes would conflict with
  changes planned for v7.4

All the code has spent a considerable amount of time in linux-next.

Thanks,
Bartosz

  power: sequencing: pcie-m2: Add Foxconn WCN7850 subsystem PCI ID (2026-10-16 15:41:21 +0200)

----------------------------------------------------------------
power sequencing updates for v7.4-rc1

Power sequencing core:
- add a suite of kunit test cases for the power sequencing core
  functionalities
- provide a new consumer API: pwrseq_is_controllable()

New Drivers:
- add the Renesas RZ/G3L Power Ready driver which provides information
  on power readiness for various IPs on RZ/G3L

Driver changes:
- use pwrseq_is_controllable() to report controllability to consumers in
  pwrseq-qcom-wcn and pwrseq-pcie-m2
- add support for PCIe switch topologies to pwrseq-pcie-m2
- add the PCI ID for Foxconn WCN7850 to pwrseq-pcie-m2
