Subject: [PATCH v2 1/3] dt-bindings: arm: Convert UniPhier board/SoC bindings to json-schema
Date: Sat, 22 Feb 2020 15:04:33 +0900	[thread overview]
Message-ID: <20200222060435.971-1-yamada.masahiro@socionext.com> (raw)

Convert the Socionext UniPhier board/SoC binding to DT schema format.

Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Changes in v2:
  - Remove 'examples' because examples are fold into /example-0 node
    and there is no way to meet
