Subject: [PATCH 3/4] arm64: dts: rockchip: add rk3588 gpio aliases to soc dtsi
Date: Fri, 1 Dec 2023 17:58:09 +0100 [thread overview]
Message-ID: <20231201165810.334212-4-heiko@sntech.de> (raw)
In-Reply-To: <20231201165810.334212-1-heiko@sntech.de>
From: Heiko Stuebner <heiko.stuebner@cherry.de>
The gpio controllers on rk3588 are named gpio0 - gpio4. Board schematics
also use these exact numbers and we want those names to also reflect
in the OS devices because everything else would just cause confusion.
Userspace gpio access is a thing afterall.
So instead of having each board repeating their list of gpio aliases move
them to the soc dtsi, as previous Rockchip soc like the rk356x do already.
