Tegra SoC support the configutaion of IO pads to multi-level voltage
and low power state. The conifguration is done via pictrl framework
and the io pad driver in pinctrl frameowrk uses the APIs from pmc to
access PMC registers.
his series add the API to get the IO pad power status and register
the pmc child devices like IO pad drvier.
The patches were send earlier part of different series but applied
partially in the Thierry's t186 branch
https://github.com/thierryreding/linux/tree/tegra186.
Resending the patches as the new start to avoid any confusion.
This need to be applied in
https://github.com/thierryreding/linux/tree/tegra186
