Note: This patch set depends on my previous patch set [1] which adds Root Port device tree nodes and support parsing the reset property in new Root Port binding in pci-imx6 driver. This series integrates the PCI pwrctrl framework into the pci-imx6 driver and updates i.MX EVK board device trees to support it. Patches 2-8 update device trees for i.MX EVK boards which maintained by NXP to move power supply properties from the PCIe controller node to the Root Port child node, which is required for pwrctrl framework. Affected boards: - i.MX6Q/DL SABRESD - i.MX6SX SDB - i.MX8MM EVK - i.MX8MP EVK - i.MX8MQ EVK - i.MX8DXL/QM/QXP EVK - i.MX95 15x15/19x19 EVK The driver maintains legacy regulator handling for device trees that haven't been updated yet. Both old and new device tree structures are supported.
