Subject: [PATCH 1/1] dt-bindings: serial: Add label property for pl011
Date: Thu, 15 Apr 2021 15:31:05 +0800	[thread overview]
Message-ID: <20210415073105.3687-1-thunder.leizhen@huawei.com> (raw)

When there is more than one pl011 serial port present, the label property
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
