[PATCH v3 0/2] dt-bindings: PCI: uniphier: Fix endpoint descriptions

[Kunihiko Hayashi]

This series fixes dt-schema descriptions for PCI endpoint controller
implemented in UniPhier SoCs.

Changes since v2:
- Move some items to minimize if/then schemas in Patch 2
- Remove Patch 3 because the warning comment is for an unmerged source

Changes since v1:
- Fix "config" in the Patch 1 commit message to "addr_space"

Kunihiko Hayashi (2):
  dt-bindings: PCI: designware-ep: Increase maxItems of reg and
    reg-names
  dt-bindings: PCI: uniphier-ep: Clean up reg, clocks, resets, and their
    names using compatible string

[PATCH v3 1/2] dt-bindings: PCI: designware-ep: Increase maxItems of reg and reg-names

[Kunihiko Hayashi]

UniPhier PCIe EP controller has up to 5 register mappings (dbi, dbi2, link,
addr_space and atu), so maxItems of "reg" and "reg-names" should allow 5.

[PATCH v3 2/2] dt-bindings: PCI: uniphier-ep: Clean up reg, clocks, resets, and their names using compatible string

[Kunihiko Hayashi]

Instead of "oneOf:" choices, use "allOf:" and "if:" to define reg, clocks,
resets, and their names that can be taken by the compatible string.

The order of their names doesn't change here.
