dt-bindings: connector: add pd-disable dependency

2026-03-30T15:19:10+00:00

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 PCIe M.2 Mechanical Key M connector

2026-01-23T08:58:05+00:00

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. The connector also supplies optional signals in the form of GPIOs for fine grained power management.

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

2025-03-13T22:43:16+00:00

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.

dt-bindings: connector: Add time property for Sink BC12 detection completion

2024-11-16T08:05:44+00:00

This commit adds a new time property for Battery charger (BC1.2) type detection completion process (based on BCv1.2 detection spec) when typec port connects in a potential sink role. BC1.2 detection is used by some Type C port controllers implementations (such as "maxim,max33359") to detect the type of charger port.

dt-bindings: connector: Add child nodes for multiple PD capabilities

2024-01-04T14:59:11+00:00

Commit 662a60102c12 ("usb: typec: Separate USB Power Delivery from USB Type-C") allows userspace to configure the PD of a port by selecting different set of predefined PD capabilities. Define the PD capability sets in DT for better configurability in device modules. Define an optional child node "capabilities" to contain multiple USB Power Delivery capabilities. Define child nodes with pattern (e.g. caps-0, caps-1) under "capabilities". Each node contains PDO data of a selectable Power Delivery capability. Also define common properties for source-pdos, sink-pdos, and op-sink-microwatt that can be referenced.
