From 6320522f617d020b0e65cabb4cc4b35518fc8222 Mon Sep 17 00:00:00 2001 From: Sherry Sun Date: Wed, 1 Jul 2026 18:52:31 +0800 Subject: arm64: dts: imx8mp-evk: Add power supply properties to Root Port node Add the power supply properties to the Root Port child nodes to support the new PCI pwrctrl framework. Legacy power supply properties are retained for backward compatibility with existing kernels. New device trees should specify power supplies at the Root Port level to utilize the pwrctrl framework.
