From eeaf1a44be8354c197107535727db9e1fa53472f Mon Sep 17 00:00:00 2001 From: Richard Zhu Date: Tue, 30 Jun 2026 10:30:06 +0800 Subject: [PATCH] arm64: dts: imx943-evk: add PCIe root port node and according properties Since describing the PCIe PERST# property under Host Bridge node is now deprecated, it is recommended to add it to the Root Port node, so creating the root port node and add the reset-gpios property in root port. Move the regulator to root port nodes as well, because that the PCI pwrctrl framework had been integrated into pci-imx6 driver. The backward compatibility is not a concern since i.MX94 is a newly introduced platform that is still under active development.
