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.
You can try to set those values by writing some u-boot script or bring the below (needed) code upstream, so those could be reused by others.

I dont have s2mps11 datasheet with me. but I tried to write simple .probe function with debug message but print message did not invoke during the booting of the device.
neither did the debug print appeared during the pmci dump command.

How can we invoke and verify the s2mps11 init function during board initialization ?
When i have checked the above values, those are the reset value at each registers. but some registers are different with reset values.
do you want to change the pmic register value at init time?
[snip]
What I have debug at my end pmci is not getting invoke or initialize via u-boot. Yes default value for all the control registers would be fine.
I was looking into some missing feature like. s2mps11 regulator initialization via dts in u-boot. s2mps11_pmic .probe = s2mps11_probe .bind = s2mps11_bind
Can we enable CONFIG_SPL_BUILD for Odroid platform. much of the core initialization is blocked under this flag. Is their any plan to make this feature working.
