Hi All,
I would like to get the s2mps11 regulator binding for u-boot to work on Odroid XU3/XU4 as in case of Odroid U3 we have max77686_bind function which dose the job.
what will be the correct way to reset s2mps11 control register to the default values in-order to support reset of some regulators.
Below is the command I tried to gather some information but it failed.

Actually, I am looking into setting some of the s2mps11 control register + reset clk values during board initialization.

Some of the feature dont work out on warm boot because of this missing feature.
