Some platforms using this controller have separated interrupt lines for
aer or pme events instead of having a single interrupt line for
miscellaneous events. Define interrupts in the binding for these
interrupt lines.

On some platforms, root port doesn't support MSI/MSI-X/INTx in RC mode.
When chip support the aer/pme interrupts with none MSI/MSI-X/INTx mode,
maybe there is interrupt line for aer pme etc. Search the interrupt

Another round of removing redundant minItems/maxItems from new schema in
the recent merge window.
If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

There are two independent PCIe controllers in MT2712 and MT7622
platform. Each of them should contain an independent MSI domain.
In old dts architecture, MSI domain will be inherited from the root
bridge, and all of the devices will share the same MSI domain.
Hence that, the PCIe devices will not work properly if the irq number
which required is more than 32.
Split the PCIe node for MT2712 and MT7622 platform to comply with
the hardware design and fix MSI issue.

The 'contains' keyword applies to elements within an array, so
using 'items' only makes sense if the elements of the array are another
array which is not the case for 'compatible' properties.
Looking at the driver, it seems the intent was the condition should be
true when 'faraday,ftpci100' is present, so we can drop
'cortina,gemini-pci'.

"A few SoC (code) changes have queued up this cycle, mostly for minor

- Adding an additional maintainer for the TEE subsystem (Sumit Garg)
- Quite a significant modernization of the IXP4xx platforms by Linus
Walleij, revisiting with a new PCI host driver/binding, removing
legacy mach/* include dependencies and moving platform
detection/config to drivers/soc. Also some updates/cleanup of
platform data.
- Core power domain support for Tegra platforms, and some
improvements in build test coverage by adding stubs for compile
test targets.
- A handful of updates to i.MX platforms, adding legacy (non-PSCI)
SMP support on i.MX7D, SoC ID setup for i.MX50, removal of platform
data and board fixups for iMX6/7.

The i.MX8MQ PCIe PHY can use either a 1.8V or a 3.3V power supply. Add a
"vph-supply" property to indicate which regulator supplies power for the
PHY.

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.
This condition is partially checked with the meta-schema already, but
only if both 'minItems' and 'maxItems' are equal to the 'items' length.
An improved meta-schema is pending.
