Subject: [PATCH v2 2/4] arm64: dts: rockchip: add rk3588 i2c aliases to soc dtsi
Date: Tue,  5 Dec 2023 17:48:40 +0100	[thread overview]
Message-ID: <20231205164842.556684-3-heiko@sntech.de> (raw)
In-Reply-To: <20231205164842.556684-1-heiko@sntech.de>

From: Heiko Stuebner <heiko.stuebner@cherry.de>

The i2c controllers on rk3588 are named i2c0 - i2c8. 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 i2c access is a thing afterall.

To prevent each board repeating their list of i2c aliases, define them
in the soc dtsi, as all previous Rockchip soc do already.
