[PATCH RESEND v10 1/3] dt-bindings: PCI: Add support for Airoha EN7532

[PATCH RESEND v10 1/3] dt-bindings: PCI: Add support for Airoha EN7532

[Felix Fietkau]

From: John Crispin <john@phrozen.org>

EN7532 is an ARM based platform SoC integrating the same PCIe IP as
MT7622, add a binding for it.

[PATCH RESEND v10 3/3] ARM: dts: Add PCIe support for Airoha EN7523

[Felix Fietkau]

This uses the MediaTek MT7622 PCIe driver, since the PCIe IP block is nearly
identical to the one in MT7622

Applied patches 1 & 2 to pci/ctrl/mediatek for v5.20, thanks!

I assume patch 3 for:

  arch/arm/boot/dts/en7523-evb.dts
  arch/arm/boot/dts/en7523.dtsi

needs to go through an ARM tree, right?
