Subject: [PATCH v4 0/5] convert designware-pcie.txt and kirin-pcie.txt to yaml

Hi Rob,

This series (in particular, the last patch) depends on this series:
	https://lore.kernel.org/lkml/cover.1626157454.git.mchehab+huawei@kernel.org/

It convert designware-pcie.txt and kirin-pcie.txt to DT schema.

This series uses a different strategy than v4: after doing lots of tests and
trying to tweak the syntax, I opted to create two files instead of one.

The first one (snps,dw-pcie.yaml) uses the pci-bus.yaml schema.
The second one (add snps,dw-pcie-ep.yaml) uses the pci-ep.yaml schema.

Without splitting it into two, I was unable to find a way that would work,
due to the need of using:

	AllOf:
	   - $ref: /schemas/pci/pci-bus.yaml#

For the non-endpoint part.

In order to make easier to review, I also opted to split the patch into
4 ones:

patch 1:
   adds the Designware PCI DT schema;
patch 2:
   adds the Designware PCI endpoint DT schema;
patch 3:
   changes the existing references to point to the new schemas.
   On yaml files, it uses the proper $ref to point to the right DT schema;
patch 4
   drops the old txt file.

Patch5 is independent: it converts the pcie-kirin.txt to DT schema and
adds a reference to the newly-converted DWC schema.

It should be noticed that I had to make a few amends at the "reg" field
on patches 1 and 2, in order to avoid warnings about some properties
found on some DWC-dependent DT schemas, as some have "addr_space",
"link", "app" and "elbi".

With this change, it now passes "make dt_binding_check".

Mauro Carvalho Chehab (5):
  dt-bindings: PCI: add snps,dw-pcie.yaml
  dt-bindings: PCI: add snps,dw-pcie-ep.yaml
  dt-bindings: PCI: update references to Designware schema
  dt-bindings: PCI: remove designware-pcie.txt
  dt-bindings: PCI: kirin-pcie.txt: Convert it to yaml
