This is not how Linux kernel development works. Read process documents before interfering with people's work. Best regards, Krzysztof

This was discussed already, but in case you didn't follow if we need to incorporate changes earlier we can't really wait the merge window for the changes to be merged first into the Linus tree. Anyway Bartosz is the maintainer of Power Sequence subsystem, and several others drivers, so I think it is safe to trust his judgment here.
From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org> Hi! These are the power sequencing patches sent separately after some improvements suggested by Bjorn Helgaas. I intend to pick them up into a new branch and maintain the subsystem from now on. I then plan to provide an immutable tag to the Bluetooth and PCI subsystems so that the rest of the C changes can be applied. This new branch will then be directly sent to Linus Torvalds for the next merge window. Changelog: Since v8: - split the pwrseq patches out into their own series - rename incref/decref functions to get/put for consistency - fix typos - make it very explicit in docs that arrays of targets and units must be NULL-terminated - Link to v8: https://lore.kernel.org/r/20240528-pwrseq-v8-0-d354d52b763c@linaro.org 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@bgdev.pl/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@mail.gmail.com/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@bgdev.pl/T/ v5: Two different ways of handling QCA6390 and WCN7850: https://lore.kernel.org/lkml/20240216203215.40870-1-brgl@bgdev.pl/ Bartosz Golaszewski (2): power: sequencing: implement the pwrseq core power: pwrseq: add a driver for the PMU module on the QCom WCN chipsets MAINTAINERS | 8 + drivers/power/Kconfig | 1 + drivers/power/Makefile | 1 + drivers/power/sequencing/Kconfig | 29 + drivers/power/sequencing/Makefile | 6 + drivers/power/sequencing/core.c | 1105 ++++++++++++++++++++ drivers/power/sequencing/pwrseq-qcom-wcn.c | 336 ++++++ include/linux/pwrseq/consumer.h | 56 + include/linux/pwrseq/provider.h | 75 ++ 9 files changed, 1617 insertions(+) create mode 100644 drivers/power/sequencing/Kconfig create mode 100644 drivers/power/sequencing/Makefile create mode 100644 drivers/power/sequencing/core.c create mode 100644 drivers/power/sequencing/pwrseq-qcom-wcn.c create mode 100644 include/linux/pwrseq/consumer.h create mode 100644 include/linux/pwrseq/provider.h
