[U-Boot] [U-boot] Odroidxu3/4 -s2mps11 bind pmic failed

[Anand Moon]

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.

Best Regards
-Anand Moon
