Wouldn't it work if you have added those properties to exynos4.dtsi, instead of having same entries in exynos4210.dtsi and exynos4x12.dtsi ?

However, base address of register is different for 4210 and 4x12. That was the reason 2 separate nodes were created. Do you want me to create a common node in exynos4.dtsi with all the common properties and separate nodes in exynos4210.dtsi and exynos4x12.dtsi with just the 'reg' property?

I'm fine either way. The compatible strings are also different so it's probably better to leave exynos4.dtsi out and have full nodes listed in both exynos4210/4x12.dtsi.

I will leave it the way it is.
