[PATCH v5 0/2] PCI: rcar: support regulators for PCIe

[Wolfram Sang]

Here are the patches to make PCIe cards work in slot CN15 on a Renesas
KingFisher board. Please apply.

Changes since v4:
* rebased to 6.6-rc2
* added ack from Mani (Thanks!)

[PATCH v5 1/2] dt-bindings: PCI: rcar-pci-host: add optional regulators

[Wolfram Sang]

Support regulators found on the KingFisher board for miniPCIe (1.5 and
3.3v). For completeness, describe a 12v regulator while we are here.
