Subject: [PATCH v4 2/7] dt-bindings: gpio: rockchip,gpio-bank: add unique hardware GPIO ID
Date: Thu, 23 Feb 2023 20:46:24 +0100 [thread overview]
Message-ID: <774d712d-bcdf-677a-2d9c-a49ed829e965@gmail.com> (raw)
In-Reply-To: <3eeaa940-9d40-5e33-bc36-c9b0449ded9f@gmail.com>
Add a unique hardware GPIO ID to the Rockchip GPIO nodes with
the "rockchip,gpio-controller" property to be independent from aliases
and probe order. "gpio-ranges" can't be used for that, because there is
no semantic restrictions on how they are set up.
