[PATCH v2 1/2] dt-bindings: PCI: mediatek-gen3: Add support for Airoha AN7583

[Christian Marangi]

Introduce Airoha AN7583 SoC compatible in mediatek-gen3 PCIe controller
binding.

This differ from the Airoha EN7581 SoC by the fact that only one Gen3
PCIe controller is present on the SoC.

[PATCH v2 2/2] PCI: mediatek-gen3: add support for Airoha AN7583 SoC

[Christian Marangi]

Add support for Airoha AN7583 SoC that implement the same logic of
Airoha EN7581 with the only difference that only 1 PCIe line is
supported (for GEN3).

A dedicated compatible is defined with the pdata struct with the 1 reset
line.

In the previous review, I also asked you to change the compatible string to be
consistent with the others.

airoha,an7583-pcie

I have just seen the other series where you add AN7583 to the GEN2 PCIe controller
driver; this means that this SoC has two controllers, one GEN2 and one GEN3.

The compatible string inconsistency is therefore acceptable.

Please, though - add this information in the commit message, saying that the new
string is inconsistent with the others and explain the reason.

After which,
