[PATCH v9 0/4] arm64: dts: qcom: add WiFi modules for several platforms

[Bartosz Golaszewski]

Hi!

Here are the DTS changes for several Qualcomm boards from the
power-sequencing series. To keep the cover-letter short, I won't repeat
all the details, they can be found in the cover-letter for v8. Please
consider picking them up into the Qualcomm tree. They have all been
thorougly tested with the pwrseq series.

Changelog:

Since v8:
- split the DTS patches out into their own series
- Link to v8: https://lore.kernel.org/r/20240528-pwrseq-v8-0-d354d52b763c@xxxxxxxxxx

Since v7:
- added DTS changes for sm8650-hdk
- added circular dependency detection for pwrseq units
- fixed a KASAN reported use-after-free error in remove path
- improve Kconfig descriptions
- fix typos in bindings and Kconfig
- fixed issues reported by smatch
- fix the unbind path in PCI pwrctl
- lots of minor improvements to the pwrseq core

Since v6:
- kernel doc fixes
- drop myself from the DT bindings maintainers list for ath12k
- wait until the PCI bridge device is fully added before creating the
  PCI pwrctl platform devices for its sub-nodes, otherwise we may see
  sysfs and procfs attribute failures (due to duplication, we're
  basically trying to probe the same device twice at the same time)
- I kept the regulators for QCA6390's ath11k as required as they only
  apply to this specific Qualcomm package

Since v5:
- unify the approach to modelling the WCN WLAN/BT chips by always exposing
  the PMU node on the device tree and making the WLAN and BT nodes become
  consumers of its power outputs; this includes a major rework of the DT
  sources, bindings and driver code; there's no more a separate PCI
  pwrctl driver for WCN7850, instead its power-up sequence was moved
  into the pwrseq driver common for all WCN chips
- don't set load_uA from new regulator consumers
- fix reported kerneldoc issues
- drop voltage ranges for PMU outputs from DT
- many minor tweaks and reworks

v1: Original RFC:

https://lore.kernel.org/lkml/20240104130123.37115-1-brgl@xxxxxxxx/T/

v2: First real patch series (should have been PATCH v2) adding what I
    referred to back then as PCI power sequencing:

https://lore.kernel.org/linux-arm-kernel/2024021413-grumbling-unlivable-c145@gregkh/T/

v3: RFC for the DT representation of the PMU supplying the WLAN and BT
    modules inside the QCA6391 package (was largely separate from the
    series but probably should have been called PATCH or RFC v3):

https://lore.kernel.org/all/CAMRc=Mc+GNoi57eTQg71DXkQKjdaoAmCpB=h2ndEpGnmdhVV-Q@xxxxxxxxxxxxxx/T/

v4: Second attempt at the full series with changed scope (introduction of
    the pwrseq subsystem, should have been RFC v4)

https://lore.kernel.org/lkml/20240201155532.49707-1-brgl@xxxxxxxx/T/

v5: Two different ways of handling QCA6390 and WCN7850:
