Subject: [PATCH v2 3/3] dt-bindings: serial: Add label property in serial.yaml
Date: Thu, 22 Apr 2021 16:58:37 +0800	[thread overview]
Message-ID: <20210422085837.513-4-thunder.leizhen@huawei.com> (raw)
In-Reply-To: <20210422085837.513-1-thunder.leizhen@huawei.com>

When there is more than one serial port present, the property 'label'
allows a custom name to be used for briefly describe the usage or position
of each serial port.

Without this "label" property, many dtbs_check warnings similar to the
following are reported:
arch/arm64/boot/dts/hisilicon/hi3660-hikey960.dt.yaml: \
serial@ffd74000: Additional properties are not allowed ('label' was unexpected)
        From schema: Documentation/devicetree/bindings/serial/pl011.yaml
