Subject: [PATCH 3/3] dt-bindings: gpio: rockchip, gpio add optional 'gpio-ranges'
Date: Fri,  4 Mar 2022 17:05:23 +0800	[thread overview]
Message-ID: <20220304090523.1748297-4-jay.xu@rock-chips.com> (raw)
In-Reply-To: <20220304090523.1748297-1-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.
