From 93fd1c2bda0dad0c95a68062cb2232a31b49d028 Mon Sep 17 00:00:00 2001 From: Abdurrahman Hussain Date: Thu, 14 May 2026 20:03:25 -0700 Subject: [PATCH] dt-bindings: trivial-devices: Add Murata D1U74T PSU The Murata D1U74T-W series are hot-pluggable 1U AC/DC front-end power supplies in the Intel CRPS-185 / OCP M-CRPS form factor. Each variant delivers a 12 V main output plus a 12 V standby output from a wide AC input (90-264 Vac) or HVDC supply, and includes an internal variable-speed cooling fan and on-board voltage, current, power, fan-speed, and temperature telemetry. The host-side digital interface is a PMBus 1.2 port on I2C. The PSU's other electrical signals (status, alert, current-share) live on the CRPS edge connector and are consumed by the chassis controller rather than the host SoC, so there are no host-described supplies, GPIOs, clocks, or interrupts. Add the compatible to trivial-devices.yaml rather than carrying a standalone binding file.
