[PATCH 2/5] arm64: dts: exynos8895: Move I2C address/size-cells to DTSI
From: Krzysztof Kozlowski
Date: Thu Mar 05 2026 - 04:15:30 EST
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.
