Subject: [PATCH 1/5] arm64: dts: exynos7870: Move I2C address/size-cells to DTSI
Date: Thu, 05 Mar 2026 10:09:24 +0100	[thread overview]
Message-ID: <20260305-dts-exynos-i2c-v1-1-2c8d3df3b9ca@oss.qualcomm.com> (raw)
In-Reply-To: <20260305-dts-exynos-i2c-v1-0-2c8d3df3b9ca@oss.qualcomm.com>

Convention followed in all other DTSI files is to define I2C controller
address/size-cells in the DTSI thus reducing code needed in each DTS.
It's also logical, since I2C is a bus and needs definition of addressing
children, even if the bus is enabled without the nodes.
