Pull power sequencing updates from Bartosz Golaszewski: "For this release we have an extension of the pwrseq-pcie-m2 driver with support for PCIe M.2 Key E connectors. The rest of the commits fulfill a supporting role: document the hardware in DT bindings, provide required serdev helpers (this has been provided in an immutable branch to Rob Herring so you may see it in his PR as well) and is followed up by some Kconfig fixes from Arnd. Summary: - add support for the PCIe M.2 Key E connectors in pwrseq-pcie-m2 - describe PCIe M.2 Mechanical Key E connectors in DT bindings - add serdev helpers for looking up devices by OF nodes - minor serdev core rework to enable support for PCIe M.2 Key E connectors" * tag 'pwrseq-updates-for-v7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: power: sequencing: pcie-m2: add SERIAL_DEV_BUS dependency power: sequencing: pcie-m2: enforce PCI and OF dependencies power: sequencing: pcie-m2: Create serdev device for WCN7850 bluetooth power: sequencing: pcie-m2: Add support for PCIe M.2 Key E connectors dt-bindings: connector: Add PCIe M.2 Mechanical Key E connector dt-bindings: serial: Document the graph port serdev: Do not return -ENODEV from of_serdev_register_devices() if external connector is used serdev: Add an API to find the serdev controller associated with the devicetree node serdev: Convert to_serdev_*() helpers to macros and use container_of_const()

dt-bindings: connector: Add PCIe M.2 Mechanical Key E connector

2026-03-31T07:48:43Z

Add the devicetree binding for PCIe M.2 Mechanical Key E connector defined in the PCI Express M.2 Specification, r4.0, sec 5.1.2. This connector provides interfaces like PCIe or SDIO to attach the WiFi devices to the host machine, USB or UART+PCM interfaces to attach the Bluetooth (BT) devices. Spec also provides an optional interface to connect the UIM card, but that is not covered in this binding. The connector provides a primary power supply of 3.3v, along with an optional 1.8v VIO supply for the Adapter I/O buffer circuitry operating at 1.8v sideband signaling. The connector also supplies optional signals in the form of GPIOs for fine grained power management.

2026-03-30T15:19:10Z

When Power Delivery is not supported, the source is unable to obtain the current capability from the Source PDO. As a result, typec-power-opmode needs to be added to advertise such capability.

dt-bindings: connector: Add sink properties to comply with PD 3.1 spec

2026-03-11T14:48:52Z

Add additional properties for ports supporting sink mode. The properties define certain hardware and electrical properties such as sink load step, sink load characteristics, sink compliance and charging adapter Power Delivery Profile (PDP) for the connector. These properties need to be defined for a Type-C port in compliance with the PD 3.1 spec.

dt-bindings: connector: Add PCIe M.2 Mechanical Key M connector

2026-01-23T08:58:05Z

Add the devicetree binding for PCIe M.2 Mechanical Key M connector defined in the PCI Express M.2 Specification, r4.0, sec 5.3. This connector provides interfaces like PCIe and SATA to attach the Solid State Drives (SSDs) to the host machine along with additional interfaces like USB, and SMBus for debugging and supplementary features. The connector provides a primary power supply of 3.3v, along with an optional 1.8v VIO supply for the Adapter I/O buffer circuitry operating at 1.8v sideband signaling.

dt-bindings: connector: Add the GOcontroll Moduline module slot bindings

2025-03-13T22:43:16Z

Add the bindings that describe a GOcontroll Moduline module slot. This slot provides all the interfaces to interface with a Moduline compatible IO module. The actual module is not reasonable to describe as it can be swapped at will, with this connector the driver will be able to probe for a module on boot. The connector consists of 2 parts, one part for interfacing with the SoC and main board, the other part has 13 IO channels for the module to interact with the outside world. The functions of these IO channels are determined by the type of module in the slot. The IO on the SoC side is as follows: - a 3v3 supply, this tends to be the logic level of the module and its microcontroller - a 5v0 supply, this can be used to power low power peripherals on the module - a 6v-8v supply, this can be used for high power peripherals on the module - a 6v-30v supply, this tends to be a dirty supply that comes from the controller supply after some circuit protection, or is the same as the 6v-8v supply. - an SPI bus which carries the communication between the SoC and the microcontroller on the module. - an I2C bus shared between the SoC and all module slots which can carry direct module-to-module communication. - a reset line - an interrupt line that indicates a clear to transmit signal - a sync line shared between the SoC and all module slots which could be used to synchronize modules for time sensitive IO spread across modules. - a SMBus alert line that is shared between the modules but is not connected to the SoC so that is ignored. A slot-number property is used to identify the physical location of a module slot. Without it, it would be impossible to identify which module to control if there are multiple of one type, to address the desired IO.
