This fixes DTC warning: > > Warning (simple_bus_reg): /regulators/regulator-0: missing or empty reg/ranges property > > Signed-off-by: Krzysztof Kozlowski Tested-by: Marek Szyprowski What about removing the regulators node from other boards: exynos4412-origen.dts, exynos5420-smdk5420.dts and exynos5250-arndale.dts? On the other hand, maybe it would be really easier to add missing address/size-cells properties to exynos4210-trats.dts/regulators node?
