[PATCH 0/8] PCI: imx6: Integrate pwrctrl API and update device trees

[Sherry Sun]

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.
