From 66738404bd0ab5b515d32bf4bd64f2cbe91a4b4d Mon Sep 17 00:00:00 2001 From: Sherry Sun Date: Wed, 1 Jul 2026 18:52:30 +0800 Subject: arm64: dts: imx8mm-evk: Add power supply property to Root Port node Add the power supply property to the Root Port child node to support the new PCI pwrctrl framework. Legacy power supply property is retained for backward compatibility with existing kernels. New device trees should specify power supply at the Root Port level to utilize the pwrctrl framework.
