Currently, it controls the voltage rails of the PCI slotsdefined in the devicetree node of the root port.The voltage rails for PCI slots are documented in the DT-schema: https://github.com/devicetree-org/dt-schema/blob/v2024.11/dtschema/schemas/pci/pci-bus-common.yaml#L153Since this driver has to work with different kind of slots (PCIex1/x4/x8/x16, Mini PCIe, PCI, etc.), the driver is thus using theof_regulator_bulk_get_all() API to obtain the voltage regulators definedin the DT node, instead of hardcoding them.As such, the DT node of the root port should define the relevant supplyproperties corresponding to the voltage rails of the PCI slot.Tested-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>Signed-off-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org>Link: https://lore.kernel.org/r/20250116-pci-pwrctrl-slot-v3-5-827473c8fbf4@linaro.org[kwilczynski: commit log]Signed-off-by: Krzysztof Wilczyński <kwilczynski@kernel.org> List of files: /linux-6.15/drivers/pci/pwrctrl/Makefile Thu, 16 Jan 2025 14:09:15 +0000 Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> http://172.16.0.5:8080/history/linux-6.15/drivers/pci/pwrctrl/Makefile#b88cbaaa PCI/pwrctrl: Rename pwrctl files to pwrctrlTo slightly reduce confusion between "pwrctl" (the power controller andpower sequencing framework) and "bwctrl" (the bandwidth controller),rename "pwrctl" to "pwrctrl" so they use the same "ctrl" suffix.Rename drivers/pci/pwrctl/ to drivers/pci/pwrctrl/, including the relatedMAINTAINERS, include file (include/linux/pci-pwrctl.h), Makefile, andKconfig changes.This is the minimal rename of files only. A subsequent commit will renamefunctions and data structures.Link: https://lore.kernel.org/r/20241115214428.2061153-2-helgaas@kernel.orgSigned-off-by: Bjorn Helgaas <bhelgaas@google.com>Signed-off-by: Krzysztof Wilczyński <kwilczynski@kernel.org>Acked-by: Krzysztof Wilczyński <kw@linux.com> List of files: /linux-6.15/drivers/pci/pwrctrl/Makefile Fri, 15 Nov 2024 21:44:27 +0000 Bjorn Helgaas <bhelgaas@google.com>
