[PATCH v5 2/2] arm64: dts: imx943-evk: Add Root Port node and according properties

From: hongxing . zhu

Date: Mon Jun 29 2026 - 22:30:12 EST


From: Richard Zhu <hongxing.zhu@xxxxxxx>

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.
