Well, the bindings should describe what is common for all SoC and they are quite different in what they need in addition.

If these properties are needed for Exynos-specific implementation, they should be in the bindings. If they are not needed, they should not be here. Take a look at midgard bindings for example. This is a nice starting point for these here. Best regards, Krzysztof

It's not necessary for proper operation as it's on by default. Looking at simple-pm-bus, I don't really understand its purpose. Is it a way of separating out a power domain from a main device's node? Or is it designed for when you have multiple devices under the same power domain?

I don't believe there is a regulator on s5pv210, if there is, then it is a fixed regulator with no control on both s5pv210 devices that I have. The vendor driver did use the regulator framework for its power domain implementation, but that definitely shouldn't be upstreamed. > BR and thanks, > Nikolaus > Thanks, Jonathan

Starting with Exynos4210 usually they have separate regulator from PMIC but maybe S5Pv210 indeed is different. Leave it then without it. Best regards, Krzysztof

Ok, this means there is no need for regulators in the bindings. BR, Nikolaus
