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.
Best Regards
