Subject: [PATCH 3/3] dt-bindings: gpio: rockchip,gpio add optional 'gpio-ranges'
Date: Thu, 1 Sep 2022 09:29:44 +0800 [thread overview]
Message-ID: <20220901012944.2634398-6-jay.xu@rock-chips.com> (raw)
In-Reply-To: <20220901012944.2634398-1-jay.xu@rock-chips.com>
Add a optional property 'gpio-ranges', such as
gpio-ranges = <&pinctrl 0 0 32>;
When the gpio nodes are under pinctrl, the property 'gpio-ranges' is
a optional property, but when they are under root node, the property
'gpio-ranges' is a required property.
