Hmmm,
Yeah, right. This is depends on physical design. And not the regulator
current limit.

Earlier, I had submitted DT based approach, but was MFD DT property.
Which is not correct, do you think regulator DT property is the right
approach?

Below is going to be my approach -

pmic1: 88pm860@30 {
	compatible = "marvell,88pm800";
	...
	regulators {
		compatible = "marvell,88pm80x-regulator";

		marvell,88pm860-buck1-dualphase-en;

		buck1: buck1 {
			...
		};
		...
	};
};


Thanks,
Vaibhav
