67006e30e2 dt-bindings: Drop more redundant 'maxItems/minItems'
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.

aa6eca5b81 dt-bindings: PCI: mediatek: Update the Device tree bindings
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.

a083fadf54 dt-bindings: PCI: faraday,ftpci100: Fix 'contains' schema usage
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'.

6e207b8821 ARM: SoC changes for 5.14
A few SoC (code) changes have queued up this cycle, mostly for minor
 changes and some refactoring and cleanup of legacy platforms. This
 branch also contains a few of the fixes that weren't sent in by the end
 of the release (all fairly 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.
 
  ... and a few smaller changes and fixes for Samsung, OMAP, Allwinner,
  Rockchip.

972d6a7dce dt-bindings: Drop redundant minItems/maxItems
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.

scripts/checkpatch.pl -f drivers/pci/controller/pcie-rcar-host.c:

    WARNING: DT compatible string "renesas,pcie-r8a7779" appears un-documented -- check ./Documentation/devicetree/bindings/
    #853: FILE: drivers/pci/controller/pcie-rcar-host.c:853:

Re-add the compatible value for R-Car H1, which was lost during the
json-schema conversion.  Make the "resets" property optional on R-Car
H1, as it is not present yet on R-Car Gen1 SoCs.
