From e27671f66321f97b62424aebacd6d9b678b0c5be Mon Sep 17 00:00:00 2001 From: Zhen Lei Date: Thu, 6 May 2021 21:20:49 +0800 Subject: [PATCH] dt-bindings: serial: Add label property in serial.yaml 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 Reviewed-by: Rob Herring Signed-off-by: Zhen Lei Link: https://lore.kernel.org/r/20210506132049.1513-3-thunder.leizhen@huawei.com Signed-off-by: Greg Kroah-Hartman --- Documentation/devicetree/bindings/serial/serial.yaml | 2 ++ 1 file changed, 2 insertions(+) diff --git a/Documentation/devicetree/bindings/serial/serial.yaml b/Documentation/devicetree/bindings/serial/serial.yaml index 2fdf4ed..c75ba3f 100644 --- a/Documentation/devicetree/bindings/serial/serial.yaml +++ b/Documentation/devicetree/bindings/serial/serial.yaml @@ -23,6 +23,8 @@ properties: $nodename: pattern: "^serial(@.*)?$" + label: true + cts-gpios: maxItems: 1 description: -- 2.7.4
