Subject: [PATCH v4 1/1] dt-bindings: PCI: uniphier-ep: Clean up reg, clocks, resets, and their names using compatible string
Date:   Fri, 23 Dec 2022 16:07:13 +0900
Message-Id: <20221223070713.20549-2-hayashi.kunihiko@socionext.com>

Content-Transfer-Encoding: 8bit
Precedence: bulk

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.
